If you have added vertex coloring or texture to your surface visualization, you can add a colorbar that will show on a color scale the minimum to maximum values of data in the visualization. To add a colorbar, click on the surface data and then from the iSurface window, select Insert ® Colorbar. A colorbar will be placed in the visualization window. 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. For more information on the colorbar, see Colorbar, Visualization Properties.
