Axis Types
In Grapher, two axes are automatically created for each 2D graph, 3D graph, and XY contour map. Three axes are created for 3D XYZ graphs, XZ contour maps, and surface maps. Axes are named according to the type of axis and the order in which they are created in the graph. For example, a line/scatter plot initially contains two axes: X Axis 1 and Y Axis 1. If X axes are added to the graph, they are sequentially numbered (X Axis 2, X Axis 3, etc.). 3D XYZ graphs, XZ contour maps, and surface maps have a Z axis in addition to the X axis and Y axis.
Axis Limits
Axis limits approximate the limits of the data file used to create the graph, depending on the tick mark spacing. The tick mark spacing is automatically scaled so a reasonable number of tick marks are drawn along each axis. Tick mark spacing and label format parameters can be independently specified for each axis on the graph. Tick labels and axis titles can also be moved with the Graph Tools | Plot Tools | Move Labels command.
Types of Axes
There are four types of axes in Grapher: standard, angle, box-whisker, and stiff X axes.
Standard Axes
Standard axes are included in the following plots:

Box Plot Axes
Box plot axes are included in box plots and in notched box plots.
Stiff X Axes
Stiff X axes are included in stiff plots.
