"Yes please" on some documentation for how to write a driver. I am no expert in this aspect of PLplot, but I do have two "overview" points to make. 1. Device drivers for PLplot have been advertised as easy to write so let's make that so with improved documentation. 2. My gut feeling is that the overview (aside from the X specifics) for the xwin device would make a good template for an interactive device driver. The reason I say that is that was the interactive device driver that got all the TLC in the early PLplot history. For example, it handles calls to plxormod and plGetCursor properly for example 20 while the other interactive device drivers currently do not. So aside from treatment of text (which is way out of date for the xwin device), I think it would be worth your while to study the design overview of the xwin device to see if it might help you to document the general design of interactive device drivers.
