Grapher Technical Information
Grapher is an easytouse and powerful graphing package. Create and organize your graphs using the Graph Wizard and the Object Manager. Grapher will help you present your data clearly and precisely. Graph types available in Grapher include Step Plots, Bubble Plots, Floating Bar Charts, Rose Diagrams, Ternary Diagrams, and BoxWhisker Plots.
Grapher Technical Information
Grapher is an easy to understand technical graphing package for anyone who needs to create publication quality graphs quickly and easily. Grapher allows you to create: 







Create your own custom graphs using the builtin Graph Wizard. Add legends, curve fits, text or drawing objects. Create templates to use the same graph settings with multiple data files. Automate the graphing process with the included Scripter program. Grapher lets you export graphs for use in presentations and publications 
System Requirements
 Windows 95/98/2000/NT/2000/ME/XP, or higher
 Suggested 20 MB of free hard disk space
 Suggested 16 MB RAM, 32 MB preferred
 800 X 600 minimum monitor resolution.
Graph Types
Display your data as thirteen different graph types in Grapher. Different graph types can be combined on one graph and multiple graphs can be created on one page.
Line and Symbol Graphs display data as a line or symbols.
Step Plots display data as vertical and horizontal lines.
Create step plots with horizontal or vertical lines.
 Bubble Plots display data varying sized bubbles. The bubble size is dependent on a third variable.
Create bubble plots to show how two variables relate to the same X variable.
 Bar Charts display data as adjacent or stacked bars. Choose to have vertical or horizontal bars.
 Floating Bar Charts display the difference between two variables. Choose to have vertical or horizontal bars.
 Function Plots display mathematical functions. Plot Y as a function of X, or plot a parametric equation where X and Y are a function of a third variable, T. Specify a function or equation to create a graph. Position the axes anywhere on the page.
 HiLowClose Graphs display a range of Y values at each X value. These plots are commonly used to display the high, low, opening and closing of stock values, though HiLowClose graphs are also used for many other purposes.
 Rose Diagrams display degree, radian, or grad data versus a radial axis. Like histograms, Rose Diagrams display statistical data, showing the number of occurrences of an event that fall within a specific angular region.
 Pie Charts show data as proportional slices of a circle. Each data value is divided by the sum of the data to determine the size of the slice.
 Ternary diagrams show the relative proportions of three variables on three axes. Choose to show the relative proportions as percentages or as fractions.
 Histograms display data separated into groups or bins.
 Box and Whisker Plots are commonly used to show the min, max, median, and lower and upper quartiles for a particular group. The caps at the end of each box indicate the extreme values (min and max).
Curve Fits
Curve fitting routines help depict trends in your data. Select predefined fits or define a custom fit to add to the graph. Display fits for Line and Symbol Graphs, Step Plots, Polar Graphs, and Histograms. There are 10 predefined curvefitting algorithms in Grapher:
 Linear
 Logarithmic
 Exponential
 Power
 Spline Smoothing
 Polynomial Regression
 Orthogonal Polynomial Regression
 Linear through Origin
 Running Average
 Weighted Average
Associate any number of fits with a single curve. Change the line style, color and width for each fit. Applicable statistics are available for each fit. The resulting statistics are copied to the clipboard or displayed in a report window. Or, export fit curve data to a worksheet.
Display data using a curve fit. Equation coefficients can also be displayed.
Template Graphs
Create a graph with the desired colors, number formats, tick mark spacing, legend styles, etc., and save it as a template graph for use with multiple data sets.
Axes
Grapher has three axis types: linear, logarithmic, and probability. Use Grapher's default settings or specify custom settings for all axis parameters. Set the axis scale, change the axis length and starting position, add additional or duplicate axes, add axis limits, enter an axis title, add grid lines or hide the axis on your graph. On each axis, you control the major and minor tick frequency and spacing or you can use Grapher's default settings. Use automatic date and time labeling or read axis tick labels from a worksheet, allowing you to use any type of tick labeling.
Display your graph with linear, logarithmic, or probability axes.
Error Bars
Error Bars are displayed on Line and Symbol Graphs. Display error bars for the average value, sample standard deviation, population standard deviation, or standard error of the mean. Or, calculate custom error bars in the worksheet and display them on the graph.
Text Editor
Easily add text objects to graphs using Grapher's text editor. Easily select any typeface, font size, and color. Add superscripts, subscripts, and symbols to your text. Automatically enter current dates and times. Create complex mathematical equations and include them in your graph.
Use Grapher's text editor to create complex mathematical equations.
Worksheet Features
 Display, enter, edit, print, and save data.
 Double precision capabilities allow up to 15 digits without loss of precision.
 Import data files in the following formats: XLS, SLK, WKx, WRx, CSV, TXT, DAT, BNA, and BLN.
 Save your data files in XLS, SLK, CSV, TXT, DAT, BNA, and BLN formats.
 Cell formatting includes background colors.
 Control cell height and width.
 Include formatting information when copying to the worksheet.
 Sort data using multiple columns.
 Calculate numerous statistical functions on individual columns of data.
 The number of data points the worksheet can handle is only limited by the amount of memory available on your computer (up to 5,000,000 rows x 5,000,000 columns).
 View a list of all worksheets associated with a graph.
Additional Features
 Set multiple levels of undo (up to 25).
 Add legends to graphs.
 Add color fill under or above curves.
 Customize Grapher by selecting the default settings.
 Control line styles, color, and width.
 Change font type, size, color, and style.
 Draw points, lines, polygons, rectangles, and ellipses.
 Create custom colors, lines, and fill patterns.
 Reshape polylines using the reshape tool.
 Combine and break apart composite objects.
 Rotate objects.
 View and edit all objects using the Object Manager.
 Show the Object Manager while editing the graph.
 Use the Arrange command to move objects forwards or backwards.
 Add a variety of arrows to the ends of polylines.
 Digitize data from a graph and write the data to a file.
 Fix the digitizing process directly to the line or digitize anywhere in the plot window.
 Display and edit detailed areas of a graph using the Zoom commands.
 Make changes to data in the worksheet and have the graph update with the new data automatically.
Automation
If you want to create repetitive graphs without manually opening a graph file each time, you can automate the process. Use Grapher's powerful scripting language to create your graphs. Grapher can also be called from Visual Basic, Visual C++, Perl, or any other OLE automation compliant language. Virtually any operation that you can perform interactively can be controlled.
In addition, Grapher includes GS Scripter, a Visual Basic compatible programming environment that lets you write, edit, debug, and run scripts. In this way, you can automate repetitive tasks, create front ends for running Grapher, or carry out any task that Grapher can do.
Import and Export Options
 Import formats include: GSB, BNA, DLG, LGO, LGS, DXF, PLT, BLN, CLP, WMF, TIF, BMP, TGA, PCX, WPG, DCX, EPS, JPG, PCT, SHP, MIF, PNG, GIF, and DDF.
 Export formats include: EMF, WMF, CLP, DXF, CGM, TIF, BMP, TGA, PCX, WPG, JPG, PCT, DCX, PNG, SHP, BNA, BLN, MIF, and GIF.
Graph Wizard
The Graph Wizard is an easy to use stepbystep tool that automatically creates a graph for you. All the wizard needs you to do is select the type of graph to create, choose the worksheet to create the graph from, and choose the columns to use from the worksheet. Add curves to existing graphs or create new graphs with the wizard.
