    Stereonet Helpthe users manual for Stereonet 8 by Rick Allmendinger, 2013

    Introduction

    Stereonet 8 is a complete rewrite of my venerable, but aging, stereonet plotting program for Windows,originally called “StereoWin”. The program has a revamped, and vastly improved, user interface,

    includes most of the scientific functionality of the older versions, and will work just fine on modernoperating systems such as Windows 7. The functionality and interface of the program has been modeled after OSXStereonet by Néstor Cardozo and Richard W. Allmendinger. The only difference is thatOSXStereonet uses an interface with a main window and two drawer windows that can be opened and closed at will, whereas Stereonet 8 version uses a single window with several different panes for different interface elements.

    Stereonet 8 was written by Richard W. Allmendinger; the interface for the program is modeled after OSXStereonet by Néstor Cardozo and Richard Allmendinger. The rotation algorithm has beencompletely rewritten from one originally written by Randy Marrett. The contouring algorithm used is“conrec” by Paul Bourke (1987). The eigenvalue and eigenvector routines have been modified from thebook Numerical Recipes. The PDF classes included in this program are from pdfFile by Toby W. RushCopyright © 2004. I am particularly grateful to comments and advice from Néstor Cardozo during thedevelopment of this program and for sharing many other programming adventures.

    Stereonet Helpthe users manual for Stereonet 8 by Rick Allmendinger, 2013

    Differences with Previous Versions

    There are several significant changes in how Stereonet 8 works relative to how older versions worked.

    When Stereonet/StereoWin was first written more than 20 years ago, personal computers wereso slow that you could literally watch them drawing individual great circles! So older versionsof Stereonet/StereoWin drew the layers of graphical elements in the order that the user specified and went to great pains to avoid redrawing previous elements. With modern systems,the graphics can be delivered all at once. So, Stereonet 8 always layers different elements inthe same order, regardless of what order the user specified. It is now possible to turn on or off different graphical elements without redrawing everything else. So, you won’t see the dreadednew plot or old plot dialog box any more. Want to turn off the great circles that you plotted sixsteps ago? Just uncheck them in the Plot menu and they will disappear while everything elsethat you drew afterwards remain intact.Plots can be saved from Stereonet 8 in now as PDF or .emf format. The former is a higher quality format so you should use that if possible. Some programs that claim to be able to read

    pdfs might claim that the file is damaged or otherwise be unable to read the file. If thathappens, just open the file in Acrobat Reader and then save it.Interaction with your data has been much improved in this version of Stereonet 8. You canclick on a point and have the corresponding row in the data table highlighted or vice versa.Data can be edited simply by clicking on the line of data that you wish to change and typing ina new value.Sorting of your data is now accomplished by clicking on the heading of the column in the datatable that corresponds to the parameter you want to sort by. The data table supports multipleselections, and you can then toggle on or off the data (i.e., check or uncheck them) based onwhether or not they are selected in the data table.A single Stereonet 8 file can contain an unlimited number of lines, planes, and small circlesdata sets. These individual data sets can be toggled on or off at will simply bychecking/unchecking them in the Data set pane.You now set all plot elements in the Inspector Window. In general, you have much greater control over the appearance of your plot than previously (see Fig. 2)Stereonet 8 can import (and export) old Stereonet/StereoWin text files that contain theappropriate two letter header, but the save and open commands now work on the new Stereonet8 binary data files. If you need to exchange data with OSXStereonet, you must export text filesfrom Stereonet 8 and then import them into OSXStereonet. At present, the binary files

    produced by Stereonet 8 and those produced by OSXStereonet are incompatible.Stereonet 8 binary files include not only the structure data but also the exact state of the

    program (including the Analysis Pane), all colors, parameters, etc.In Stereonet 8, numerical analyses are written to the Analyses pane. This is an editable textfield. Not only can you copy and paste to that field, but you can write your own notes andannotations there. Just click where you want to start writing. This field is not saved with the

    plot so, to capture its contents when you close the program, be sure to copy them to the systemclipboard and then paste them wherever you want.

    The amount of data that Stereonet 8 can hold is limited only by available memory. Earlier versions of Stereonet/StereoWin were limited to 2500 lines and 2500 planes.Stereonet 8 includes a new Data Details window where every datum can be tagged withlocation, date and time, and a free form notes field. If you have an internet connection, anydata point with location information can be visualized in Google Satellite, terrain, or roadmapviews.This beta version of Stereonet 8 is “document” based. Thus, you can open as many windowswith different data sets as you wish

    Stereonet Helpthe users manual for Stereonet 8 by Rick Allmendinger, 2013

    The basic interface

    The basic interface for Stereonet is depicted,below. You will do all of your plotting and data analysis inthe main window of the program. Individual data sets can be toggled on and off with the checkbox tothe left of the name of the data set. Likewise, you can turn on or off an individual datum (or group of data) within a single data set with the checkbox in the Data list. The results of calculations appear inthe Analysis area; this is an editable text field. You can add your own annotations or delete analysesthat you don’d need. You can also copy from or paste to that field.

    An individual datum has several attributes:

    the orientationlocation information (Latitude, longitude, elevation)time information (time, day, month, year)a freeform notes field that can hold up to 512 characters

    Only the orientation information, which can be entered in the main window, is required. The additionalattributes can only be accessed via the Data Details Window, a floating window that stays visible untilyou close it by clicking on its close icon. The Data Details Window can also display the location of your datum on a Google satellite, hybrid, terrain, or road map. the Mac version of the program displaysthe orientation symbol; the Windows version cannot.

    Stereonet Helpthe users manual for Stereonet 8 by Rick Allmendinger, 2013

    Entering new data

    To enter a new data set into the program,choose a new data set type from the popupmenu located beneath the Data Sets List or choose Data>New Data Set> . Either methodwill add a new data set and will add a line tothe data listing pane, so that you canimmediately begin entering data. For example,to enter lines data, one would first type thetrend measurement, then press the tab key tomove to the plunge column to enter the plunge measurement. After entering the plunge, if you press theReturn Key, a second line will be added automatically to enter another line of data. Alternatively, youcan click the “+” button beneath the data listing pane to add a new line of data.

    From the preferences command under the Windows

    Menu you can select the default formats for new datasets. To set default colors, styles, line weights, pointsizes, etc., set all of those features in the Inspector,then check the box, “Set to current settings inInspector” before clicking Okay in the Preferencesdialog. You can also set the default window size onstartup.

    If you need to enter more details about your data — latitude, longitude, elevation, date, time, and free formnotes — you can open Window>Data Details andenter lines and planes in that dialog box. This dialogbox can only accommodate planes data in right-hand -rule format, but has the obvious advantage that you can see exactly where the datum is located byclicking “Map Location” to show the datum in Google Satellite, terrain, or roadmap view.

    If you are entering rakes of lines on planes, Stereonet 8 will create both a lines data set and a planesdata set. These two data sets must be given the same name. If you delete the planes data set (or changeits name), you will still be able to show the lines data, but you will not be able to display it using therake (RK) format.

    The name of the data set can be edited at any time by clicking on the name (e.g., “Untitled Lines”) andthen typing in whatever you want. It is useful to give the data sets sensible names because those are

    used in various operations (e.g., poles to planes, rotations) and are saved as part of the binary file. Notethat you can set the default format for newly entered data by selecting Preferences.

    You can also add data by clicking the mouse inside the primitive of the stereonet. To enable thisoption, select “Enter with mouse” from the Data Menu. A message will appear explaining how to plotlines and planes. Anytime “Enter with mouse” is checked, you can enter a new line by holding downthe Shift Key while clicking, or enter a new plane by holding down the Alt Key. In both cases, thedatum is entered when you release the mouse, not when you click the mouse. When choosing a newplane this way, the place that you click the mouse becomes the pole to the plane; as you drag to movethe pole around, the corresponding great circle is displayed. The first time you enter data with themouse, it will be placed in a special data set named “ad hoc lines” or “ad hoc planes”. Any subsequent

    lines or planes added with the mouse will be added to the same ad hoc data set, rather than creating anew data set. As long as Stereonet 8 finds either of those two data sets listed, data entered with themouse will be added to the existing data set. You can, of course, change the name of the data set towhatever you want; however, when you do so the program will then create a new “ad hoc lines” or “adhoc planes” data set for any subsequent lines or planes entered with the mouse. In practice, these adhoc data sets will most likely be used for temporary constructions. You can turn them off with theappropriate checkboxes or delete them entirely once you are done. They are saved with the binary file.

    Deleting Data

    You can delete an individual datum by selecting the line of data in the data list pane and then pressingthe “–” button located beneath the data list pane. The datum will be deleted and the remaining linesbeneath the datum will be shifted upwards. If yo have a multiple selection in the data list pane, only thefirst line of data will be deleted.

    To delete an entire data set, selected in the Data Set pane and then press the “–” button located beneaththe data set pane (i.e., to the right of the add data set buttons). The data set and all of its associated datawill be deleted.

    No warning is given when you press the “–” for either data sets or individual lines of data!! Theyare simply deleted.

    Stereonet Helpthe users manual for Stereonet 8 by Rick Allmendinger, 2013

    Saving data files

    Likewise, Stereonet 8 can save data files in two formats:

    Save Stereonet 8 Native Binary File

    The “Save As…” command under the file menu saves a Stereonet 8 native (binary) file with the filesuffix “.stnt”, which can only be read by Stereonet 8. As described above, these files contain an exactcopy of the state of the program and data at the time that you save the file. The Stereonet 8 native filecannot be read by any previous version of Stereonet.

    The binary file is very convenient for its completeness however no other program, not evenOSXStereonet, can read this file. F or l ongevity of your precious data, I highl y r ecommend also saving i t as a text fi le as described below:

    Exporting Text Files

    You can export text files in two flavors: if you want to save a text file with a two line header, just likeolder version of Stereonet/StereoWin, choose Stereonet 6 Format. Lines are only saved with the TP(trend, plunge) format and planes are saved only with the AD (Azimuth Dip, i.e., right hand rule)format. Use export text file if you want to exchange data with OSXStereonet or with older versions of Stereonet/StereoWin.

    You can also save text files in Table format. In this flavor, you get a one line header with column labelsand you save all of the location information (longitude, latitude, elevation, notes) as well as theorientation data. These file can be read back in to Stereonet 8 using the Parse Text File option, above.

    In either case, only the selected data set is saved.

    Export to .KML Files

    Lines or planes data can be saved as a .KMLfile using Tom Blenkinsop’s (2012) great3D symbols by selecting File>Export TextFile>Kml File. This will produce the dialogbox to the right where you can specify thesymbol shape and color. Advanced choicesare shown below the disclosure triangle andare not initially visible. Do not change anyof the values there unless you know whatyou are doing.

    If you have designed your own symbols anduploaded them to a publicly accessibleserver, you can replace the symbol URLwith your own. If you click 2D symbols,they will look more “normal” when lookingstraight down in Google Earth, but willdisappear completely when you rotate theview away from vertical!

    Stereonet Helpthe users manual for Stereonet 8 by Rick Allmendinger, 2013

    Opening data files

    Opening Stereonet 8 Native FilesStereonet 8 introduces a new binary file format that, in a single file, contains not only all of the data setsentered, but also all of the settings at the time the file was saved. This includes all of the formatting youhave applied to the stereonet (e.g., colors, grid spacing, projection, etc.), the data (e.g., colors, symbols, line weights, etc.), the plot itself, and the contents of the Analysis pane. Opening a Stereonet8 native file is just like picking up exactly where you left off when you last saved the file. Stereonet 8can read Stereonet 7 binary files, but Stereonet 7 cannot read Stereonet 8 binaries!

    Opening column formatted text files (e.g., from spreadsheet programs)

    Stereonet 8 can also parse any text file that has be formatted into columns using a separator character.The program parses the columns automatically: if tab characters are present they will be used as aseparator; if tabs are absent, commas will be used and if commas are absent, spaces will be used. In the

    latter case, the program assumes that contiguous spaces are a single separator, so this is clearly the leastdesirable option for such files. The Parse Text File dialog box is shown, below

    The labels and numbers of popup menus for columns changes depending on what is selected in thepopup menu “The data in this file are:”. Simply chose the column in which each data type appears andStereonet 8 will read in the column. You can skip specific rows of data by deselecting the checkbox onthe left side. For many people, this will be the most convenient way to enter details such as locationinformation, etc.

    Importing text files with Stereonet 6 formatting code

    Using the “Import Text File” command under the File Menu, you can read in a text file that has a twoletter header on the first line of the text file. These were the only sorts of files that could be used withStereoWin and versions of Stereonet for Mac versions 6 and earlier. The following table has adescription of the two letter codes that Stereonet 8 recognizes:

    Following the one line header, there were any number of lines, each with only one datum (e.g., trendand plunge, or strike and dip) followed by a return character. The values on the line can be separated bya comma, space, tab or any combination.

    Choosing which data to plot or analyze

    Stereonet 8 will only plot or analyze data that are checked in the Data List pane to the right of the plot,and it will only plot data sets that are checked in the Data Sets Pane. The program makes it easy to link data in the plot to the table in the data list box by highlighting selected points and planes in yellow, aneffect I call the “selection halo”. If you click on a point in the plot, the row will be selected in the table,and clicking on a row provides a selection halo in the Plot Window. You can multiple, non-contiguousselections in the table of the Data List pane by command clicking the rows of interest. From the DataMenu, or equivalent popup menu in the Data Drawer accessed by right-clicking, you can toggle on or off selected data.

    The Toggle On and Off commands in the Data Menu can be very powerful when combined the abilityto sort rows by clicking on a column in the table of the data list pane. The first time you click a columnheading all the rows will sort ascending, the next click will sort descending. To return to the originalsorting, click the “No.” heading of the column farthest to the left. Once sorted by whatever criteria youwant, you can then select the range of rows that fits your criteria and Toggle Off the rest of the data set.

    Stereonet 8 also allows you to search a single data set or all data sets for matching parameters byselecting Data>Search which will give you the dialog to the right. Here you can specify anycombination of matching tag criteria by checking the checkbox to the left of the name. In the exampleshown to the right, pressing “select” will toggle on only those measurements in the currently selecteddata set that have trends between 350 and 010°, elevations between 800 and 1200, and have the phrase“Salar Grande” in the notes field. If you elect to search across all data sets, then the trend or the strikewill be between 350 and 010°, etc. Click select opposite to toggle on those measurements which doNOT meet the entered criteria. Finally, the “Restore All” button will turn on all measurements in alldata files.

Select a plot type once to turn it on and asecond time to turn it off; the plot will automaticallychange to reflect your selections. If a plot option is checkedat the time of data entry, the points (or great or smallcircles) will appear interactively as you enter each datum.The same plotting options are applied to all checked datesets in the Data Set pane. For example, turning on scatter will make a scatter plot for all lines data sets. If you do notwant a data set to appear in a plot, then turn it off byunchecking it in the Data Set pane. As described above,only data that are checked in the Data List Pane will beplotted.

    Plotting is specific to data set type. For example, youcannot contour a Planes data set. To produce a contour diagram of poles to planes, you must first make a Linesdata set containing the poles, which you do by choosing“Poles” from the Calculation Menu.

    Some of the options in the Plot menu write the results of the underlying analysis to the Analysis Pane.For example, if you choose Mean Vector from the Plot menu, the mean vector statistics will also bewritten to the Analysis pane. At any time, you can erase extraneous information that you don’t needfrom the Analysis pane by selecting it and pressing the delete key on the keyboard.

    Using the Inspector

    The appearance or formatting of your plot, including the type of projection (equal area or equal angle) iscontrolled by the Inspector, which is accessed from the View Menu. There are a large number of choices in the Inspector, thus giving you many options for formatting the plot to your liking. Anychange that you make in the Inspector is immediately reflected in the plot.

    Click on one of the images below to go to the description of that Inspector tab.

    The second tab controls the appearance of individualdata sets. The changes you make in this tab apply onlyto the data set that is selected in the Data Set Pane. If you have three lines data sets entered, only the one thatis selected will acquire the properties that you enter. If a lines data set is selected and you try to change theappearance of planes, nothing will happen because theplanes data set was not selected. Lines can be assignedone of four different symbol types, either hollow or solid, and can have any color. “Plot as connected linesegments” only applies if you have entered a latitude-longitude data set (line format type 3). Lines can have

    either positive (lower hemisphere) or negative (upper hemisphere) plunges. Stereonet 8 always plots negativeplunges with the same symbol and color, but oppositehollow-type than positive plunges. For example, if asingle lines data set is set to use hollow triangles, anynegative plunges will be plotted as solid triangles (or vice versa). You can choose to plot negative plunges ineither the upper or the lower hemisphere, but they willstill have the opposite hollow setting from the positiveplunges in the data set. Small circles always break across the primitive, but you can select to plot the small circle entirely in the upper or the lower hemisphere.

    The third tab controls the appearance of various typesof analyses that you can apply to your data such asBingham Axes (Cylindrical Best Fit), the mean vector,and rose diagrams. If the “use individual data set colorsand symbols is used” the colors that you set here willbe overridden by the existing colors which have beenset for the individual lines and planes files. This is aglobal setting for all analyses on this tab.

    If your data set has both positive and negative plunges,as is common with paleomagnetic data sets, you canchoose to plot a separate mean vector for positive and

    negative populations, and chose to plot the negativemean vector in the lower hemisphere. Doing so wouldbe equivalent to performing a paleomagnetic reversaltest.

    The fourth tab is where you control the appearance of your contour plots. Like the items on the Analyses Tab,changes in the Contours Tab apply to all lines data sets.If you want to plot the contour lines with the samecolor as used for the different lines data sets, make surethat “Use individual data set colors and symbols” at thetop of the Analyses Tab is checked. The contour interval is appropriate to both Kamb and 1% areacontouring, but the significance is only pertinent to theformer. You can turn on or off contour lines with thecheckbox of that name. Color sets the color for thecontour lines (for all data sets) assuming that it is not

    overridden by the “Use individual data sets colors…”checkbox. Eventually, you will be able to fill the regions between contour lines with solid colors, butthat has not yet been implemented. The Contour fillcheckbox will control that choice.

    The Terzaghi Correction is intended for data that yousample along a 1-D linear transect (borehole, etc.),which can be biased by the fact that you are veryunlikely to sample a representative number of structures that trend sub-parallel or parallel to your sampling line. As Randy Marrett explained it to me,to apply the Terzaghi correction for this bias, you just multiply the value at each counting node times1/cos(angle between the sample line and the counting node). The trend and plunge that you enter in theInspector’s Contours Tab gives the orientation of the sampling line or transect. Counting nodes that areparallel to the sample line should have a value of infinity, but that would result in an awful lot of contours, so you must specify some upper maximum value, the default value being 10.

    Stereonet Helpthe users manual for Stereonet 8 by Rick Allmendinger, 2013

    Changing the View Direction of Your Plot

    Structural geologists are accustomed to viewing the stereonet as a lower hemisphere projection, as if one were looking vertically downward. However, there are many times when a different frame of reference is better. For example, you may want to plot data in the plane of a cross section (a viewdirection which is horizontal and perpendicular to the azimuth of the cross section), or in the profileplane (down plunge view) of a cylindrical fold (a view direction parallel to the fold axis). Of course,you can do this by rotating all your data, but it can be a bit tedious, and you don’t have andvisualization aids. Stereonet now allows you to set any view direction without having to rotate all of your data.

    When you choose “Set View Direction…” under the plot menu, the above dialog box will appear. Thetrend and plunge that you enter in this dialog will become the new center of the projection and theprimitive plane perpendicular to that direction. You can easily return to the default view of North-East-Down by clicking the “Default View” button in the set view dialog box. You do not need to enter anyvalues first. The following diagram shows the relationship between the Cartesian coordinates of a

    normal geographic stereographic projection (in black) and those of the new view (in red).

    The new view coordinate system axes are plotted at the same position as the old axes. For example, thenew X´3 is plotted in the center of the net at the same place as the old X3. Stereonet does not modifyyour data in any way; you will see no change in the orientations in the Data List box.

    To maintain a sense of orientation, I highly recommend that you have “Show Grid” turned on inPreferences; Stereonet will then plot the rotated grid, with the great circles intersecting at the north or south pole. This essentially lets you see both coordinate systems at once. For the values shown in theabove dialog, the rotated grid with the new and old coordinate systems, is shown below. Note that for the entered values, X1, X2, and X3 are all positive, but other view directions can result in negativeaxes being plotted.

    When you click and hold down the mouse on the stereonet, the orientation that you see is in geographiccoordinates. That is, if you click on the pole in the above diagram, the trend and plunge will show“T&P = 0, 0”, or perhaps “T&P = 360, 0”. This is the fastest way to determine whether or not the poleshowing is north or south (the latter, of course, will have a trend of 180°). Clicking on points above thehorizon will show negative plunges, because these points are plunging upwards into the upper hemisphere, negative by standard structural convention. If you hold down the shift key while you click on the stereonet, you will see the trend and plunge of the clicked point in the new view coordinatesystem. It is unlikely that you will need this very often!

    One potentially confusing aspect of this new capability is the concept of “upper” and “lower”hemispheres. Once you set the view direction, the upper hemisphere is the one in the direction oppositeto the direction in which you are looking. Lines that plunge downward geographically (and thus havepositive plunges) may well end up in the “upper” hemisphere of the new view. When you chooseScatter or Mean Vector, Stereonet will ask you how you want to handle these “upper” hemisphere lines.

    Rotate Data

    Your data can be rotated about an axis of anyorientation. Rotation magnitudes are positive if theyare clockwise looking in the direction of the givenazimuth and plunge of the rotation axis, and negativeif they are counter-clockwise. The data are alwaysrotated as vectors: If the rotation produces a line witha negative plunge (pointing into the upper hemisphere), it will not be converted into a lower hemisphere line. However, you can manually convertit to the lower hemisphere by selectingCalculations>Convert to lower hemisphere.

    As shown in the rotation dialog box to the right, youhave the choice of rotating just the selected data set

    or all of the data sets in the Data Sets Pane.Additionally, you can specify that the rotation replacethe existing data sets or that new data sets be created.

    Stereonet can also unfold data by rotating theassociated bedding back to the horizontal. In theUnfold Bedding dialog box, you select the lines or planes file to be rotated, and the planes data set thatcontains the bedding to be unfolded.

    Note that unfolding bedding is a counterclockwise rotation about the right hand rule strike of bedding.The example shown at the right depicts the trivialcase of rotating bedding poles to vertical by rotatingthe bedding to horizontal.

    Angle between…

    If two lines are selected in a data set you can choose to calculate theangle between them, which is essentially the angle in the plane thatcontains both lines. Both the angle and the two lines selected will berecorded in the Analysis pane.

    If two planes are selected in the same data set, the program willcalculate not only the angle between the two planes but the line of intersection as well. The result willbe written to the Analysis pane

    -----Angle between Lines | 8/10/2011 at 10:18 PM-----

    Angle = 27.1° or 152.9°

    Line of intersection = 016.7, 12.4Planes selected (RHR): 347.0°, 24.0° and 259.0°, 14.0°

    Finally, you can also use the mouse to click on two points inside the stereonet and the angle betweenthose two points will be displayed in a dialog box and you will be given the option of writing theresults to the Analysis Pane.

In the second, you provide theplane and the program will calculate the apparentdip in the direction of the given trend, or the twotrends that have a given plunge in the plane of bedding. The results can be written to either anew or existing data set for plotting, and can alsobe written to the plot record. The apparent dipcalculator is a floating window that will stayopen until you close it.

    Direction Cosines

    This command will write out the direction cosines of any selected lines, or the poles to any selectedplanes, to the Analysis Window. The entries are tab separated, making it easy to copy the results fromthe Analysis pane and paste them into a spreadsheet or other document:

    Copying, saving and printing your plot

    Once you have the plot just as you like it, you can save it as a PDF file for import into other programs.The PDFs produced should be of publication quality and should appear identical to, but higher resolution than, the plot window itself. The size of the pdf is controlled by the size of the Plot tab in theMain window.

    Alternatively, Stereonet 8 can save plots as scalable vector graphics (.svg), an open, high resolutionvector format that can be read by all major web browsers and most modern vector graphics programs(e.g., Illustrator, EazyDraw, etc.). SVG has many desirable characteristics and is the best one to use if your graphics program supports this format.

    Finally, you can save your plot in an older vector format by choosing “Save Plot as PICT/EMF” whichwill save the plot as an enhanced metafile format in Windows. PDF and SVG output is superior toPICT/EMF and is thus highly recommended1.

    Stereonet 8 also supports the clipboard. If any text is selected in either the Data List or the AnalysisPane, that editable text will be copied to the clipboard. Otherwise the Graphic in the Main Window willbe copied as vector objects to the clipboard for pasting into another application. The application intowhich you paste the graphic will determine the format in which it appears. In Mac OS X, Cocoaapplications, it will usually appear as a Tiff image, whereas Carbon apps will recognize the vectors.The clipboard uses .EMF quality graphics and thus should not be used for final production work if youcan help it.

    Stereonet 8 has a very basic printing routine which will print the graphics in the Plot pane, again using.EMF quality graphics. At present, the graphic is printed at the size it appears on the screen unless it islarger than 7 inches, in which case it is shrunk to fit the screen. The default size of the graphicswindow produces a stereonet that just fits on one page. The text in the Analysis Window/Pane isautomatically added beneath the stereonet. On the Mac OS X, you can print to PDF as you can in other programs, however, the pdf that is produced by the save plot as pdf command is higher quality than

    that saved from the print window.

    Interactive Features

    Whenever the mouse moves over the stereonet, the trend and plunge at the tip of the cursor isdisplayed in the lower left corner Clicking and dragging the mouse inside the stereonet temporarily displays a great circle whose

    pole coincides with the tip of the cursor.When “Enter with mouse” is checked under the Data Menu, you can enter data by clicking anddragging the mouse inside the stereonet. Hold down the Shift Key to enter Lines; hold downthe Alt Key to enter Planes.Clicking on a data point in the stereonet selects the corresponding row in the data table andvice versa. Multiple, noncontiguous selections are possibleChanges made in the Inspector are instantly reflected in the plot
