Hi Jim I fully agree that the plplot coordinate system is rather a mess. There are talks of units of mm in various places device coordinates, which as you have implied are not really device coordinates because the drivers report larger values to give good resolution. We discussed this a month or so back I think and mostly thought that using a float or double precision internal coordinate system was probably a good idea, but as you say it is way too close to release time to start dealing with that now - of course you can create a local branch and feel free to play with that as you want providing you keep your work for this release cycle separate.
In particular I have just been trying to deal with text size, which is an utter nightmare, given that plplot claims to work with text size in mm, but includes a scale factor which changes this then wxWidgets works in pt, but actually the output is in pixels and the conversion between the two does not appear to be that well defined and depends on your settings in the OS. Windows also will scale your text for you on high resolution displays unless your manifest indicates you are high dpi aware in which case it won't. But the fact that this occurs in the manifest means it is in the hands of the executable writer, not the library so that will be fun to deal with! Anyway, you see my point - this could probably all do with simplifying in some way.
