Hello,
how do I style the leader lines in a pie chart. I would like to set the color of the lines leading from the pie-piece to the label to be white instead of default black.
This is possible in the powerpoint UI but I cannot find the corresponding properties in the Slides.API

thank you for your support,
Kind Regards,
Kris

@ckoster,
With Aspose.Slides for .NET 23.5, you can set the color of leader lines in a Pie chart like this:

using (Presentation pres = new Presentation("example.pptx"))
{
    IChart chart = (IChart) pres.Slides[0].Shapes[0];
    IChartSeriesCollection series = chart.ChartData.Series;
    IDataLabelCollection labels = series[0].Labels;

    labels.LeaderLinesFormat.Line.FillFormat.FillType = FillType.Solid;
    labels.LeaderLinesFormat.Line.FillFormat.SolidFillColor.Color = Color.FromArgb(255, 255, 0, 0);
}
