I have always had trouble with getting IE to draw graphs from moodle using ASCIIsvg. graphs from other sites with ASCIIsvg work fine.
I finally did the following.
in meta.php i add a line to point to ASCIIMathMl.js - I believe that had already been written about. This still didn't get it to work.
I then checked that d.svg was in the same directory. But that got me thinking about the path to d.svg was by default the same as ASCIIMathMl. I then went and added the full path to d.svg in the dsvglocation variable in ASCIIMathMl and voila all graphing now works, - so it appears that IE is not understanding my relative path from within my moodle site
Have others had this problem? Is there a better way to deal with this?
