It wouldn't be even hard to write such a device, especially after I solved all the problems with the wxpng, etc. devices. But it seems that wxpdfdoc is kind of abandoned. I'm always reluctant to develop something using a library which is abondoned. Sadly, libharu is also not very active any more. > >> wxWidgets is slower, but not extremely slower.

With your experience with plplot - would that work? Sure. Keep in mind, that PLplot doesn't provide any rotating or zooming features. So in fact (this is what I do in my application) you are responsible for "remembering" all plot commands. If you zoom or rotate you need to "replot" the Plot yourself telling PLplot to plot a new Plot (with different axis, etc.). Therefore it's easy only to show the axis, since this is what you tell PLplot to draw. You could also e.g. decrease the number of plotted points while rotating so that you about see what the plot would look like but it would be fast. > >> Still the wxWidgets driver can be optimized for speed, but this was >> not my main task in the past, since it was fast enough for me. >> >> Regards, >> Werner > > > It's very nice to find such a complete open source plotting library > AND it's being still actively developed.
