| Graph Types |
|
Display your data as one of more than 30 different graph types in Grapher. 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.
- Line and Scatter plots display data as a line or symbols. Combine line and symbols or use only the line or only symbols. Display the data as a traditional 2D line/scatter graph.
|
|
 |
Create line plots with plotted symbols, comments, and fit curves.

- Ribbon/wall plots are similar to line plots, but are shown with a 3D aspect!
|
|
 |
Ribbon/wall plots can be customized with comments, fit curves, error bars, and legends.

- Bubble Plots display data with varying sized symbols. The size of the symbol is dependent on a third variable. Change the bubble to any symbol! In Grapher, you can use a 2D bubble plot that displays three variables or a 3D bubble plot that shows the change in four variables. Use solid colors, gradient fill colors, multiple fill colors, or any combination of color choices to fill your bubble plots!
|
|

|
|
 |

- Contour plots are a 2D representation of 3D data. Contour maps may either be situation on the XY plane or the XZ plane. Maps can be generated from data files or Surfer® grid files. Choose from either a default color fill or set your own color fills!

| 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 Scatter Graphs, Step Plots, Polar Graphs and Histograms. There are 11 pre-defined curve-fitting algorithms in Grapher: |
|
 |
Display data using a curve fit. Equation coefficients can also be displayed.

|
- 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.
Add confidence intervals to your fit curves to show the degree of confidence that is in the fit. Fill between confidence upper and lower bounds to highlight the certainty.

|
| 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.
|
|
| 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, change 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!

|
| 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.
|
|
| 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. Grapher 7 adds the ability to quickly move labels for most graph types with the mouse. Select only the label you want to move and effortlessly drag it to a new location. Labels can also be moved with the keyboard for finer adjustments.
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.
