Series Points coloring in ColumnStacked100 chart

Aspose.Slides Product Family

Dear,


I am using ASPose.Slide version 6.5 to generate a .pptx presentation.
Is it possible to set the coloring of some particular “Series Points” in a ColumnStacked100 chart. If this is doable, can you please provide me with a code snippet for my request.

Kindly find attached 2 snapshots CurrentColoring.png and SeriesPointColoring.png.
CurrentColoring.png shows the coloring of the chart that I am actually having. Based on some business rules in my application i need to set the coloring of some particular Points as shown in SeriesPointColoring.png (green color) and not all the series.

Thank you so much,
Sami Simon

Hi Sami Simon,


I have created the sample code for you with which you will be able to change the chart series colors. Please share, if I may help you further in this regard.

public static void ChangeSeriesColor()
{
PresentationEx pres = new PresentationEx();
SlideEx slide = pres.Slides[0];
ChartEx chart = slide.Shapes.AddChart(ChartTypeEx.StackedColumn, 100, 100, 300, 300);
ChartSeriesExCollection seriesCollection=chart.ChartData.Series;
ChartSeriesEx series = seriesCollection[0];
series.Format.Fill.FillType = FillTypeEx.Solid;
series.Format.Fill.SolidFillColor.Color = Color.Green;
series = seriesCollection[1];
series.Format.Fill.FillType = FillTypeEx.Solid;
series.Format.Fill.SolidFillColor.Color = Color.Yellow;
series = seriesCollection[2];
series.Format.Fill.FillType = FillTypeEx.Solid;
series.Format.Fill.SolidFillColor.Color = Color.Cyan;
pres.Write("D:\\Aspose Data\\ChartExample.pptx");
}


Many Thanks,

Dear,


Thank you so much for your quick reply, but in fact this is not my request.
What i really want to do is to change the colors of “certain points” in the series and not all the series.
As you can see from my first screenshot, I was able to set the color of the the second series to “Purple”. But my question is: is it possible to change the color of some points in the series? As shown in second screenshot, I want to keep the series color “Purple” but only change the color of points “G2” and “G4” to green.

Thank you,
Sami Simon

Hi Sami Simon,


I like to share that the issue shared has been resolved. Please use the following sample code to serve the purpose. Please share, if I may help you further in this regard.

public static void ChartWithSeriePointColor()
{
PresentationEx pres = new PresentationEx();
SlideEx slide = pres.Slides[0];

ChartEx chart = slide.Shapes.AddChart(ChartTypeEx.StackedColumn, 100, 100, 300, 300);

ChartSeriesExCollection seriesCollection = chart.ChartData.Series;

ChartSeriesEx series = seriesCollection[0];
series.Format.Fill.FillType = FillTypeEx.Solid;
series.Format.Fill.SolidFillColor.Color = Color.Green;


series = seriesCollection[1];
series.Format.Fill.FillType = FillTypeEx.Solid;
series.Format.Fill.SolidFillColor.Color = Color.Yellow;

series = seriesCollection[2];

ChartPointEx point = new ChartPointEx(series);
point.Index = 0;
point.Format.Fill.FillType = FillTypeEx.Solid;
point.Format.Fill.SolidFillColor.Color = Color.DeepSkyBlue;
series.Points.Add(point);

point = new ChartPointEx(series);
point.Index = 1;
point.Format.Fill.FillType = FillTypeEx.Solid;
point.Format.Fill.SolidFillColor.Color = Color.LightGreen;
series.Points.Add(point);

point = new ChartPointEx(series);
point.Index = 2;
point.Format.Fill.FillType = FillTypeEx.Solid;
point.Format.Fill.SolidFillColor.Color = Color.Orange;
series.Points.Add(point);

point = new ChartPointEx(series);
point.Index = 3;
point.Format.Fill.FillType = FillTypeEx.Solid;
point.Format.Fill.SolidFillColor.Color = Color.OrangeRed;
series.Points.Add(point);

series.Format.Fill.FillType = FillTypeEx.Solid;
series.Format.Fill.SolidFillColor.Color = Color.Cyan;

pres.Write(@“D:\Aspose Data\ChartExample.pptx”);
}
