## Adding Axes

You can also add axes to your contour as visual aids for reading contour data. Although axes are added to two-and three dimensional contour data there are advantages to adding additional axes. For example in the figure which follows, additional axes have been added in order to create a box-style contour showing the tick marks and increments on all sides of the image. You can add X, Y and Z axes depending on your contour and needs. To insert axes, select Insert Axis and then select X Axis, Y Axis, or Z Axis or from the Visualization Browser, select the Axes group and then set Style to Box Axes.

Once you have placed an axis on your contour you can edit the axis settings by changing the title and increments as well as the color options on the axis. Double-clicking on the axis itself will show you the Visualization Browser.
