How to change the Color of Column

By using Aspose.Cells to generate a Column Chart, is it possible to change the color of column under NSeries?

Please try:

chart.NSeriesIdea [I].Area.ForegroundColor = Color.Red;

Thanks. I found that not some colors such as OrangeRed, DarkGray did not work properly. They will turned into white.

Those colors are not included in the standard color palette. You should change the palette first. Please check .
