Solving the non-amuzing build problem was easier than I thought: I now use the newer CMake version that I built on Cygwin, not the one that comes with the platform. I used that in the comprehensive tests, but not yet to build the libraries and examples on their own. While it is good to be able to build PLplot again without any problems, it is a riddle why the stock version of CMake does not work. As I get a new computer next week, I will have the opportunity to re-install Cygwin and see whether this was simply a quirk (may I blame it on alpha particles or the phase of the moon?) or something more serious. To Sergej: The good news is that I have been able to get the histogram to be drawn. Instead of 0 I use as option to the plhist() routine a value of 1. This forces it not to redefine the window (not to call plenv()). As to why a value of 0 causes it to produce an empty plot, is something I would like to find out - it works in example x05c after all. See the attached picture (I used 6 bins instead of 11, to see if the bins are done correctly).
