Trying to find a solution to heat maps on IE7/IE8 (i.e. not using Canvas/HTML5/heatmapapi). Any ideas?

Which kind of "heatmap" are you referring to? A raster image with gently (or not) graduated colors? Or a polygon "chloropleth" map. –  jvangeld Apr 11 '12 at 21:03
Example: ArcGIS Javascript API HeatMap sathyaprasad.appspot.com/heatmapapi.html Firefox/Chrome fine - chokes on IE –  Mapperz Apr 11 '12 at 21:10
I'm looking for a "classic" colored gradient like this (patrick-wied.at/static/heatmapjs), but for it to work in IE7. I've seen posts which allude to this being possible (code.google.com/p/canvas-text/source/browse/trunk/…) but have not seen any end product... –  Phil Penn Apr 11 '12 at 22:36
There is an Esri blog posting called Heat Up Your Webmaps which may be useful for anyone who is using HTML5 to try and do this. –  PolyGeo Oct 16 '13 at 0:05
