Hi all,
I have a family of graphs to draw in Metapost and I would like to attribute a
different color to each of them according to the value of a certain variable.
Assuming that the path mygraph(j) depends on the variable j, which is computed
within a lua code and passed to Metapost, I wonder if it is possible to define
an array of colors named mycolor, so that I could say
draw mygraph(j) withcolor mycolor(j) ;
Here the variable j takes integer values (say between 1 and 10), and one would
have defined mycolor(1) through mycolor(10).
\startMPpage
string MyColors[] ;
path MyPaths [] ;
MyPaths[1] := fullcircle scaled 3cm; MyColors[1] := "red";
MyPaths[8] := fullsquare scaled 3cm; MyColors[8] := "green";
draw MyPaths[1] withcolor MyColors[1] ;
draw MyPaths[8] withcolor MyColors[8] ;
