The problem is that I don't know: - how to use symbol sets inside MetaFun (verbatimtex \usesymbols[jmn] etex doesn't work here) - how to enable label(btex \convertnumber{gnuplot}{5} etex, (x,y)) to work properly in metafun (no luck with verbatimtex ... etex again)
Any hints would be appreciated.
I am very much a beginner at metafun, so the following is probably garbage, but to its defence I can say that it actually achieves the goal :) There are two files: % myenv.tex: contains the symbol definition \usesymbols[jmn] \defineconversion [gnuplot] [$\bullet$, $\circ$, $\star$, x, {\symbol[navigation 1][NextJump]}] % end % sym.tex: the main file \environment myenv \startMPinclusions def draw_symbol(expr X, Y, Number) = label(textext(char 92 & "input myenv " & char 92 & "convertnumber{gnuplot}{" & decimal Number & "}"),(X,Y)) enddef \stopMPinclusions \starttext \startuseMPgraphic draw_symbol(0,0,3); \stopuseMPgraphic \useMPgraphic \stoptext % end I could not figure out how to use a 'verbatimtex' preamble either, so this loads the myenv definition file for each label. Ugly, but the best I can manage with my current knowledge. Cheers, Taco
