Alternatively, a specific number of colors can be supported (e.g., 255). The non-RGB mode is more common on older computers with display cards with more limited memory. In this mode, there is typically a trade-off between the number of colors and the video resolution (i.e., as the resolution goes up, the number of available colors goes down).

This library does not provide an automatic method for determining which color mode is in effect. The blank screen is caused by Dataplot assuming the wrong color mode. By default, Dataplot uses the non-RGB color mode. If you get a blank screen (this is actually a black foreground on a black foregroun
