Seems IE9 does support canvas element. The problem with JHS gnuplot is possibly that the html is missing some headers that are required to prevent IE9 running in a compatibility mode that does not support canvas. There are some suggestion on the net on how sort this out but I won't be able to test until later next week.
Suggestions are: add Doctype header to the html file created in ~temp/gnuplot <!DOCTYPE html> and/or add <meta http-equiv="X-UA-Compatible" content="IE=Edge"/> to force IE to run latest stuff or click F12 and turn off compatibility mode or just use Firefox or Chrome ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
