## Adding a Colorbar

You can add colorbars to your visualized volume which will show on a color scale the minimum to maximum values of data in the visualization. To add a colorbar, click on the volume visualization and then from the iVolume window, select Insert Colorbar. Colorbars showing RGB values as well as opacity values will be placed in the visualization window. These colorbars can be resized and moved around the data space. You can also double-click on the colorbars to invoke the Visualization Browser which will allow you to change the properties for that colorbar.
