## Adding a Colorbar

You can add a colorbar to your visualized contour which will show on a color scale the minimum to maximum values of data in the visualization. To add a colorbar, click on the contour data and then from the iContour window, select Insert Colorbar. A colorbar will be placed in the visualization window.

Note Be sure that the Use palette color setting in the Visualization Browser is `True` so that colors can be used. After that, you can choose or set your own color scheme from the Levels Color Table Edit color table function.

This colorbar can be resized and moved around the data space. You can also double-click on the colorbar to invoke the Visualization Browser which will allow you to change the values for the colorbar and edit color tables. For more information on the colorbar, see Colorbar.
