Hi Rene,
I got the alternative to shows the colour changed bar chart in composite window.
1. Have a datawindow to only have the graph
2. Use syntax: dw_1.SetSeriesStyle("gr_1", "ABC", Foreground!, 9188608) to make change of bar's colour
3. Save the datawindow as image: dw_1.SaveAs(path+'Graph.wmf',wmf!,TRUE)
4. Add a picture control in the composite datawindow, and point to the image directory above, to insert the image in composite datawindow.
It works....
Thank you for your kind advise.
Begards,
