CalcXSizeValues() incorrect for invisible chart

[marder]

Hi.

I just regarded that THorizBarSeries.CalcXSizeValues() does always return 0 if the containing TChart is located on an not visible form (TeeChart Pro V2011).

I use this function for preparations of the series marks before exporting/printing a chart (automated export without showing gui).
The export of the chart works correctly, but calling CalcXSizeValues() on the series always returns 0 in this case.

I also tried calling Invalidate() and Repaint() on the chart, but the result is the same.

Is this a known issue?
Can you provide me any workaround?

Thanks for your help!

Hi Marder,

Try with a Draw call. I've made a simple testing project and this call seems to make the difference. It's attached.
