Another option might be to use a marker such as
% DE_figure_here param1 param2 param3
in your ConTeXt source and then use 'awk' or another Unix text pre-processor to
scan through for these, run the appropriate DE calculation, plot the graph and
generate the appropriate \placefigure command to go in its place.
Bonus marks if it can automatically generate the caption based on the
parameters! But if not, the marker can always follow the \placefigure macro e.g.
\placefigure
{This is a DE showing something and something else}
% DE_figure_here param1 param2 param3
so the awk code only needs to insert the image file name.
Note I’ve deliberately omitted the braces from the bit to be substituted so
that you need to generate them in the awk. That way, if you forget to process,
you’ll get an error not a missing image.
