A variant of the titles is the tab title. This is just another option you have of putting a name on the graph. The appearance of this type is a tab on top of the plot area with text inside.
You can access the tab using the 'tabtitle' property of the graph.
The following figure shows an example of how this can look.
As usual you have full freedom to specify font and colors for this type of title. Please see the class reference regarding GraphTabTitle() for more information.
