Of course the user would have to make a conscious decision by enabling this “beta” release. If people could test this and with the right announcement I hope that some people would step up to test and contribute by submitting bug reports or writing documentation. > > One thing coming to my mind though that hopefully the wheel is not > > reimplemented.

I meant coloring part of the area below a graph. For example if you look at the graphic for Riemann sums on page 51 of the document »Learning MetaPost by Doing« [6]. > Gnuplot terminal uses metapost output.

Or also because it is a little less work to define the coordinate system and legends? Otherwise MetaPost seems to include all functionality Gnuplot offers and seems to offer more possibilities, does not it? > The ConTeXt terminal was almost included until developers > realized that they wanted me to throw away some code for handling > units and replace that code with something buggy (like "size 10cm,10" > -> (10cm,10cm); "size 10,10cm" -> (0.35cm,10cm) or (25.40cm,10.00cm) > depending on weather).
