What are context menus?
Context menus are what you see when you click your right mouse button. With RGraph, you can specify custom menus for your graphs if you wish. This way you can define custom actions to be associated with menu items. Context menus are a very easy way to extend the functionality of your graphs, allowing you to associate presentation style functionality with them. Important: Opera does not allow you to customise the context menu, so with this browser you should use the left mouse button on the graph, instead of the right.
