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.
Create bar charts with horizontal or vertical bars. Specify bar width for a customized graph.
  • Floating Bar Charts display the difference between two variables. Choose to have vertical or horizontal bars.
Create floating bar charts with two variables. Change the orientation to display vertical or horizontal.
  • 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.

  • Hi-Low-Close 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 Hi-Low-Close graphs are also used for many other purposes.
Track stock performance with the High-Low- Close Graph. Overlay a best-fit curve to predict future performance.

  • Polar Graphs display 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.

  • Display degree, radian, or grad data versus radial distance on a Polar Graph.
    • 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.
    Display degree, radian, or grad data versus radial statistical data on a Rose Diagram.
    • 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.
    Display the pie together or explode a slice. On a Pie Chart, choose how to label each slice.
    • Ternary diagrams show the relative proportions of three variables on three axes. Choose to show the relative proportions as percentages or as fractions.
    Display the Ternary Diagram with or without labels. Choose the order in which to display the labels.
    • Histograms display data separated into groups or bins.
    Display statistical information on a Histogram Graph. Set the bin size and the number of 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).
    Display statistical information on a Histogram Graph. Set the bin size and the number of bins.

    Curve Fits

    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 Symbol Graphs, Step Plots, Polar Graphs, and Histograms. There are 10 pre-defined curve-fitting 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.

    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.

    Graph Wizard

    The Graph Wizard is an easy to use step-by-step 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.
