Same issue here. I do have the height and width specified with a % (i.e. "100%") and it works in Firefox but not in IE. After dropping the % sign and just set both height and width to "100", the same problem in IE still persists and has appeared in Firefox as well. I tried updating the FusionChart.js to just use and not use for IE and it seemed to work, but the chart is initially displayed in full black before appearing. Any more suggestions?
