Grapher

Grapher Overview

Grapher is the ultimate technical graphing package available. This easy-to-use, powerful, dynamic program will help you create superior publication-quality professional graphs in minutes! Wow your audience every time they see your graphs.

Basic Graph Types

All graph types in Grapher give you full control over all graph parameters. Combine multiple graph types to present your data in a completely new way! Alter any property of any of the graph types to create compelling new graphs. You can accept the intelligent Grapher defaults to automatically create a plot, or click any aspect of the graph to easily customize those features.

Statistical Graph Types

Statistical type graphs include 2D and 3D histograms, pie charts, doughnut plots, and 2D box-whisker plots and Q-Q plots. Histograms can be displayed either horizontally or vertically. Box-whisker plots can be displayed with or without notches. Pie charts and doughnut plots can be displayed in 2D or 3D. Q-Q plots can compare two different data sets or any data set to the normal distribution. As with all graph types in Grapher, you have full control over all graph parameters.

Polar Graphs

Polar plots display data on polar coordinates, using degree, radian, or grad data versus a radial distance. The degree, radian or grad data are displayed on a circular angle axis. The second axis is a radial axis showing the distance from the center of the circle. Polar plots can display mathematical functions, line/scatter data, vectors, class plots, bars, rose diagrams (histograms), or wind charts. In addition, a special type of polar graph, a radar graph, is also available.

Specialty Graphs

Specialty graph include high-low-close plots, vector plots, ternary diagrams, and stiff diagrams. Each graph has its own rules and displays in a completely unique way. As with all graph types in Grapher, you have complete control over all aspects of the graph.

Contour and Surface Maps

Contour maps can be displayed over any contour range or interval. You can color fill the contours in any way you would like. Add a color legend to make reading the contour map even easier! Contour maps can be created directly from a data file or from a Surfer GRD file. As with other graph types, you have full control over all options.

Surface maps display XYZ data in a smooth color filled surface. Surface maps use color and shading to emphasis changes in data.

Customize Your Graph

Graphs can be customized in many different ways. Each portion of the graph can be altered to fit your needs. Set the axes to several different scales, link multiple axes, add graph titles, legends, summation plots, graph magnifiers, or drawn objects to complete the graph in exactly the way you want.

Fit Curves

Curve fitting routines help depict trends in your data. Select pre-defined fits or define a custom fit to add to the graph. Display fits for Line and Scatter Graphs, Step Plots, Polar Graphs and Histograms.

Axis Types

Grapher has four axis scales: linear, logarithmic (base 10), natural logarithmic, and probability. Use Grapher’s default settings or specify custom settings for all axis parameters.

Axes can be linked so that changes to one axis automatically change other axes.

Error Bars

Error Bars are displayed on Line and Symbol Graphs and on Bar Charts. 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. Once you have the error bars displayed exactly as you want them, connect the error bars with a line or export the error bar values to a new data file

Graph Wizard

The updated Graph Wizard is an easy to use step by step command that creates a graph for you using default, customizable parameters. Select the type of graph, the worksheet and the columns to use and the wizard does the rest. Add curves to existing graphs or create new graphs with the wizard. After the graph is created, it can be edited by double clicking on any portion of the graph.
