Dear Hans,

please consider the following example in MKII:

\setupcolors[state=start]

\starttext

\startMPextensions a := \abc; color b; b := \MPcolor{currentcolor}; \stopMPextensions

\startuseMPgraphic{bla} fill fullcircle scaled a withcolor b; \stopuseMPgraphic

\def\abc{3cm}\color[blue]{\useMPgraphic{bla}}

% Nice small black circle \def\abc{1cm}\useMPgraphic{bla}

\stoptext

I still don't know how to reproduce this in MKIV.

Use \startMPinitializations instead of \startMPextensions, it's global to all MP instances, though.

Thank you very much. I hope that the module in https://github.com/mojca/context-gnuplot/ is hotfixed now, thanks to Marco's extensive support. If anyone is willing to do a couple more basic tests, I would be grateful. I plan to upload this version to CTAN to get it into TeX Live and our distribution. Apart from that, Marco is working on a heavily modified version of the module (for MKVI). Once that one is tested, we'll upload it as well, but this patch is just to make the module usable again. I'm very sorry that it took me so long. Mojca
