Pie Chart Label BackColors

[Laura]

Hi,

 The label in my Pie Chart has the same backcolor as the Series.  How do I make that white?

Hello Laura,

Thank you for contacting us. 

You can subscribe to the LabelFormatting event and set the BackColor and BorderColor to Color.Transparent. Here is the code snippet: 

private void Form1_Load(object sender, EventArgs e)
{
    this.radChartView1.AreaType = ChartAreaType.Pie;
    PieSeries series = new PieSeries();
    series.DataPoints.Add(new PieDataPoint(50, "Germany"));
    series.DataPoints.Add(new PieDataPoint(70, "United States"));
    series.DataPoints.Add(new PieDataPoint(40, "France"));
    series.DataPoints.Add(new PieDataPoint(25, "United Kingdom"));
    series.ShowLabels = true;
    this.radChartView1.Series.Add(series);
    this.radChartView1.View.Palette = KnownPalette.Arctic;
    this.radChartView1.LabelFormatting += radChartView1_LabelFormatting;
}

void radChartView1_LabelFormatting(object sender, ChartViewLabelFormattingEventArgs e)
{
    e.LabelElement.BackColor = Color.Transparent;
    e.LabelElement.BorderColor = Color.Transparent;
}

More information about customization of chart labels can be found on the following link: ChartView >> Customization >> Formatting Series Labels. 

I hope this helps. Should you have further questions please do not hesitate to write back.
