How do I explicitly set the fill color of a series in a ChartEx?

Hi Jason,

Thanks for your interest in Aspose.Slides.

Please use the following code snippet to change the color of series.

series.Format.Fill.FillType=FillTypeEx.Solid;

series.Format.Fill.SolidFillColor.Color=Color.Blue;

I have a need to change the color of a column on a chart for a single data point in a series. For example the Series values would be: 4, 5, 8. I need the 4 bar to be red, the 5 bar to be yellow, and the 8 bar to be green. Is this possible? I confirmed that I can change the color of a entire series but, I can not figure out how to change the color of only a single data point.

Hi Jason,

You can change the color of columns on a chart by using the following code snippet.

int chartIdx = chartSheet.Charts.Add(ChartType.Column3DClustered, 0, 5, 0, 5);
Aspose.Cells.Charts.Chart chart = chartSheet.Charts[chartIdx];
chart.NSeries[0].Area.ForegroundColor = Color.Red;
chart.NSeries[1].Area.ForegroundColor = Color.Black;
chart.NSeries[2].Area.ForegroundColor = Color.Blue;

Thanks for the information Jason…

In the Aspose.Slides product, I do not have the Cells namspace and I do not have the NSeries property on my ChartEx object.

To help define the requirement here, I have attachech a slide with the desired formatting. As you can see the data is all one series and each data point has a diferent color. I need to accomplish this with the Aspose.Slides product.

Thanks,

Jason

Hi Jason,

I regret to share with you that you can not change the color of each datapoint in Aspose.Slides at the moment. However, you can change the color of series as I mentioned before.

We apologize for your inconvenience.
