[Solved] PieChart how to hide Legend area

[qwer]

Hi all,

I set LegendDisplayMode="None", but I can still see the Legend Colum. (above pie chart in my uploaded picture)

<telerik:PieSeriesDefinition ShowItemToolTips="True" LegendDisplayMode="None">

I want to hide the whole Legend Area as I want to show as (below pie chart in my uploaded picture).
And I don't want to show ItemLabelFormat which is 0.00%.

Please advise for my requirements.

I'm using MVVM approach, so no code behind file.

Thanks in advance.

Hi,

To make the chart Legend invisible set the Visibility property to Collapsed:

radChart.DefaultView.ChartLegend.Visibility = System.Windows.Visibility.Collapsed;

To disable the Percentage appearance of the pie labels just remove the ItemLabelFormat code line.

I hope this helps.

Kind regards,

Thanks for reply
and invisible for Legend is working.

For ItemLabelFormat, I want to show ItemLabel % when value is greater than 0, I don't want to show ItemLabel% when which is equal to 0%. Any Advise?

thanks

Hello,

To be able to show Percentage format for those pie slices that are not 0 you can use this approach:
Subscribe to ItemDataBound event of the chart. Then set Percentage LabelFormat property if DataPoint's YValue is not 0 like this:

private void radChart1_ItemDataBound(object sender, ChartItemDataBoundEventArgs e)
        {
            if (e.DataPoint.YValue != 0)
            {
                e.DataPoint.LabelFormat = "#%{p}";
            }
        }
