Grapher Description

Grapher Graph Types

Display your data as 22 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.

Create line plots with plotted
symbols, comments, and fit curves.

  • Floating Bar Charts display the difference between two variables. Choose to have vertical or horizontal bars. Choose between 2D and 3D floating bar charts!

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. Function plots can be shown in a 2D or 3D orientation.

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.

  • Bar Charts display data as adjacent or stacked bars. Choose to have vertical or horizontal bars. Bar charts can be displayed as 2D or 3D!


Create bar charts with horizontal or
vertical bars. Add error bars directly to your bar chart!

  • Bubble Plots display data varying sized bubbles. The size of the symbol is dependent on a variable. Change the bubble to any symbol!

Create bubble plots to show how
two variables relate to the same X variable.

Create step plots with horizontal or vertical lines in 2D or 3D.

  • Step Plots display data as vertical and horizontal lines. Display your step plot as either 2D or 3D.
  • Ribbon/wall plots are similar to line plots, but are shown in 3D!
  • 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.

  • Polar Function Graphs display mathematical functions. Plot radius as a function of angle, or plot a parametric equation where both the radius and the angle are a function of a third variable, T. The angle axis can be in degrees, radians or grads data.

    • Display mathematical functions
    on a Polar Function 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. Bins are fully customizable in rose diagrams!

Display custom bin sizes, grid lines,
and custom ticks with radial statistical data
on a Rose Diagram.

  • Wind Charts graph frequency vs. wind direction. Bins are created according to the wind speed. The frequency can be viewed as counts, relative frequency, or as percentages of relative frequency. Bins are fully customizable!



    • Separate wind speed in different
    bins according to wind direction
    on a Wind Chart.

  • 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. Add lines to connect the points on the ternary diagram!

Display the Ternary Diagram with or without labels.
Add lines between the points to show trends.
 

    Histograms display data separated into groups or bins. Add labels, a Gaussian fit, and display the Y axis as relative frequency to change the display of this graph. Display histograms as either 2D or 3D!

     

Display statistical information on a
Histogram Graph. Set the bin size and the number of bins.
 

  • Box-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 median, first and third quartiles and
outliers in a Box-Whisker plot.
 

  • 3D XYZ Plots are used to display the location of points with three variables. Display the data as lines and symbols and add plot labels.

    • Display lines and symbols in three dimensions
    with the 3D XYZ Plot.

Grapher 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 curve-fitting algorithms in Grapher:

  • Linear
  • Logarithmic
  • Exponential
  • Power
  • Spline Smoothing
  • Polynomial Regression
  • Orthogonal Polynomial Regression
  • Linear through Origin
  • Running Average
  • Weighted Average
  • Gaussian (available only for histograms)

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. Export fit curve data to a worksheet to calculate additional statistics. Change the range of data used to create the fit curve and the range of values to display the fit curves individually.

Display data using a curve fit.
Equation coefficients can also be displayed.

Grapher 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.

Project Files

Create a graph with the desired worksheet and save it as a project file. Project files save the data used inside the file. After the graph is created and saved as a project file, the external worksheet can be deleted.

Grapher Axes

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. 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, break the axis, 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. If the data uses date and time as one of the data columns, axis labels are automatically generated using dates and times. In addition, manual date/time labels can be created or labels can be read from a worksheet, allowing you to use any type of tick labeling.

Break axes and display dates to interpret
your data faster!


Date and Time Compatibility

Use date and time entries in the worksheet as a data column in Grapher 4. Grapher will automatically use date and time labels on the axis. Clip the curve, limit the axis minimum and maximum using date and time values. Set axis tick marks based on a calendar frequency such as once per month, twice per year, or once per every four hours.

Graph date and time entries directly from the worksheet.
Display worksheet ticks quickly with dates.

Grapher 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.

Labels and Curve Filling

Labels can be added to most graph types. All properties of the labels can be changed easily, including numeric format, adding bold, or italics, changing the font size or style, or changing the label color. In addition, labels can be moved so that neighboring labels do not overlap. Most graph types also support curve filling. Fill can be defined between two curves or by using a single curve. With a single curve, fill above, below, to the left, or to the right of the curve. Choose to fill to the axis minimum or maximum or to a customized data value.

Fill curves to the left, right, up, or down.
Add labels and move to avoid overlap.
 

Grapher 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.
