[CharFX in Updatepanel is always invisible]

I have a ChartFX7 chart in a Ajax updatepanel version 2.0 and .net 3.5 no matter what I  do the chart is invisible.  If I remove the updatepanel it works fine, with the updatepanel the chart is invisible but a grid right next to the chart diplays correctly.
