Color Palettes
Color palettes allow you to define the colors that are used in graphs and to allocate those colors to specific series. There is a general, default palette and you can also define a color palette for a specific session. You can add new colors to a palette and delete existing colors from a palette, but a palette must contain at least thirty two colors.
When a new session is created, or when you open an existing session that does not have a Graph Colors file, the general color palette is used. When you open an existing session that has a Graph Colors file, that file is used.
The colors are allocated to the graph in the order they appear in the palette. Colors allocated to a series are used to represent graph elements for the series in the order by which the colors were allocated. To change the colors in the graph, update the palette, close and re-open the graph.
