Pie chart legend location

[Josh]

Hi,

I'm trying to create a winform with a few different charts. I'm starting with the pie chart and having a couple issues.

1) I want to have the legend on the left hand side. Under ChartElement, I can see the LegendPosition and have set that to "Left" and in design time I can see it on the left. However, when I run the app it moves back over to the right side.

2) I also want to move legend closer to the pie chart. I found under ChartElement, LegendElement, PositionOffset, I can set that to 100 and it moves it closer, however because of problem 1 above it moves it off the form durning run time (it looks fine at design time).

3) It's displaying the values as percent (%), but in this case I want a hard number. How can I remove/change it from percent base?

Attached is a screen showing how I would like the final look.

Thanks!

Hello Josh,

Thank you for writing.

When I set the ChartElement.LegendPosition property to LegendPosition.Left, it is displayed as expected on my end. The ChartElement.LegendElement.PositionOffset property is also respected. I have attached my sample project. Could you please specify the exact steps how to reproduce the problem so I can investigate the precise case? Thank you in advance. 

As to the percentage value, note that each PieDataPoint is visualized as a pie slice with arc size directly proportional to the magnitude of the raw data point’s value. That is why the value is represented as a percentage of the whole part. The LabelFormatting event is appropriate for customizing the series labels:

private PieDataPoint pieDataPoint;
private PiePointElement piePointElement;

private void radChartView1_LabelFormatting(object sender, ChartViewLabelFormattingEventArgs e)
{
    pieDataPoint = e.LabelElement.DataPoint as PieDataPoint;
    if (pieDataPoint != null)
    {
        e.LabelElement.Text = "Value: " + string.Format("{0:###,##0.00}", pieDataPoint.Value);
    }
}

I hope this information helps. Should you have further questions I would be glad to help.

I have the same problem.  I looked at the designer.cs file and there were no entries for Legend position.  It seems that the Property dialog does not update the designer correctly, at least in this case.

I ended up manually editing the designer.cs file and it works now.

Hello, Thomas, 

Thank you for writing.  

The provided information is not enough for me to replicate the issue locally. The ChartElement.LegendPosition property controls the position of the legend items. If you are experiencing any difficulties with it it would be greatly appreciated if you can specify the exact steps how to reproduce the problem. Alternatively, feel free to submit a support ticket where you can provide a sample project demonstrating the issue. Thus, we would be able to make an adequate analysis of the precise case and assist you further. Thank you in advance.

Should you have further questions I would be glad to help.
