Hello,

it looks useful...

So far, I can't see any binding between GSL's 'graph.plot*()' and any
output that would be accepted by ConTeXt; e.g. no .png nor MP code can
be produced from GSL.

it should not be to hard (for luigi, given his mf project) to add output to mp

save(filename[, w, h])

Save the plot in a file in a bitmap image format. The first argument is the file name without extension while the other optional arguments are the width and the height in pixels of the image. The format used is BMP on windows and PPM on Linux.

save_svg(filename[, w, h])

Save the plot in the given filename in SVG format. Two optional parameters can be given to specify the width and height of the drawing area. If the “svg” extension is not given it will be automatically added.

On the other side, I often manage to export a kind of lua table (if possible) and use lua /mplib of context to produce a single pdf of each graph.
