Set color of PIE Slices using FreeSpireXls c#

[steveh54]

Is there a way to set each pie slice in a series to specific colors using FreeSpireXls C#?

I am working with your example Pie in C#, and I do not see an example on how to set slice colors programmatically.

Thanks

Found an answer in another similar post:

Code: Select all

ChartSerie sers = sheet.Charts[0].Series[0];
int datapoints=  sers.Values.Count;
for (int i = 0; i < datapoints; i++)
{
    switch (i.ToString())
    {
        case "0":
            sers.DataPoints[i].DataFormat.Fill.ForeColor = Color.Red;
            break;
        case "1":
            sers.DataPoints[i].DataFormat.Fill.ForeColor = Color.Yellow;
            break;
        case "2":
            sers.DataPoints[i].DataFormat.Fill.ForeColor = Color.Green;
            break;
        case "3":
            sers.DataPoints[i].DataFormat.Fill.ForeColor = Color.Blue;
            break;
        case "4":
            sers.DataPoints[i].DataFormat.Fill.ForeColor = Color.Black;
            break;
    }
}
