If I save a graph with customized styles, how will this graph appear on a colleague's computer who does not have those particular styles?

The graph will appear exactly as it did on your computer. Although every aspect of your graph's customization is encapsulated within graph styles, all customization applied to your graphs are fully portable. In fact, your colleague can then save the styles within your graph into his/her system by doing the following: first, click on the background of the graph and then right-click on the Graphic Styles box on the Graph Tools toolbar. In the shortcut menu that is displayed, select the Save As command.

The Save As dialog is then displayed. Use this dialog to specify the name for the new graph style and click the OK button. In this manner, the graph style that was originally installed on your system has now been ported to your colleague's system in a few simple steps, using a graph as a "carrier."
