PieChart legend not showing the name

[Vincent]

As you can see in my screen capture, the name is not showing in the legend of the pie chart.

    Here is the code : 

setup.NomSetup contain the string name

var serie = new PieSeries()
 {
     ShowLabels = true,
     RadiusFactor = 0.9f,
     Range = new Telerik.Charting.AngleRange(270, 360)
 };


 foreach(var setup in setups){
     serie.DataPoints.Add(new PieDataPoint(Convert.ToDouble(setup.SommeUseTime * 100 / timeclocks.First().SommeTempsStd), setup.nomsetup)
     {
         Name = "Test"
     });
 }

pieChart.Series.Clear();

pieChart.Series.Add(serie);
pieChart.ShowLegend = true;

Hi Vincent,

Thank you for writing.

I have used the following code with our latest version and the labels are shown as expected on my end.

RadChartView pieChart = new RadChartView();
this.Controls.Add(pieChart);

var serie = new PieSeries()
{
    ShowLabels = true,
    RadiusFactor = 0.9f,
    Range = new Telerik.Charting.AngleRange(270, 360)
};


for (int i = 0; i < 5; i++)
{
    serie.DataPoints.Add(new PieDataPoint(Math.PI * i, "Slice " + i)
    {
        Name = "Test"
    });
}

pieChart.Series.Clear();
pieChart.AreaType = ChartAreaType.Pie;
pieChart.Series.Add(serie);
pieChart.ShowLegend = true;

You can see the result in the attached image. 

Since the code is pretty much the same, my guess is that the setup.nomsetup variable does not return a non-empty string. Can you please check that?

Hi, 

This is the chart I get if I use your part of the following code :

int i = 0;
foreach(var setup in setups){
    i++;
    serie.DataPoints.Add(new PieDataPoint(Math.PI * i, "Slice " + i)
    {
        Name = "Test"
    });
}

Please see the attached files... it's still not working.

Hi Vincent,

Thank you for the clarification.

We had an issue causing this behavior, and this issue is already resolved in our latest version. I have tested with it, hence I did not observe the same behavior as you. Feel free to upgrade to our latest version in order to benefit from the fix.

If you are unable to upgrade, on the issue page we do have a workaround provided: http://feedback.telerik.com/Project/154/Feedback/Details/121076-fix-radchartview-pieseries-do-not-show-the-legend-properly-the-values-are-not.

I hope that you find this information useful. Should you have any other questions, do not hesitate to contact us.
