The most recent update to the DataGraph Beta includes new color scheme options and updates to the Plots command.
In the current release version of DataGraph (version 4.1), you can get suggested color schemes that depend on the number of items in your list. These suggested schemes were limited to 12 items or less.
In the most recent Beta, there are two new color schemes, a Rainbow and a Gray scale color scheme, that can be created for longer lists. You can also easily create custom color schemes that interpolate between two colors.
The Plots command is only in the Beta and the most recent Beta version has given this command a significant face lift. The Plots command allows you to quickly create multiple line graphs and vary the color of each.
