Phil, Do you have a small test program to illustrate this? It would be useful to check other drivers with. I suspect you are right in that this is on a driver-by-driver basis.
Actually, it's pretty trivial to make a quick check. I just tried putting a \n into the label of the x00 plot. A very quick look at some common drivers suggests that xcairo, epsqt, pscairo, jpgqt support line breaks. xwin, qtwidget, wxwidgets, psc don't support line breaks but produce some strange symbol instead. Note I think this is different to your experience with wxwidgets so it may even be library version dependent. Can you confirm with my simple test and the wxwidgets driver? I have wxwidgets 2.8 installed. So it looks like there is no consistency in approach at the moment. I guess the first step is to decide what we think should happen.
