Hello,
When I apply heat map in MSIE, it says "No support for this browser configuration".
It works with Chrome.
Why?
Heat maps are not supported in IE. This is a known limitation of using IE with EM4C. See heatmap documentation (http://doc.arcgis.com/en/maps-for-cognos/author-maps/apply-a-heat-map.htm ) and the KB article on the limitations of IE (http://support.esri.com/Products/Apps/plug-in-apps/esri-maps-for-ibm-cognos/6#knowledge-base/technic...)
