[Solved] Label position for exploded pie piece

[Daniel]

Hi. I've got a databound pie chart. In the code behind I explode a specific piece of the pie. This works okay but the label next to it doesn't move with the piece, so the label is half way into the pie piece. I tried setting the LabelLocation to Outside or Auto and this doesn't seem to fix the problem. Thanks.

    <telerik:RadChart ID="rcOcbgPart3" Skin="Simple" DefaultType="Pie" AutoLayout="True"
        Width="680px" Height="350px" runat="server" DataSourceID="sdsOrs">
        <Series>
            <telerik:ChartSeries Name="reqcount" DataYColumn="requests" Type="Pie" DataLabelsColumn="call_type"
                Appearance-LegendDisplayMode="ItemLabels" Appearance-LabelAppearance-Visible="false">
            </telerik:ChartSeries>
        </Series>
        <PlotArea Appearance-FillStyle-FillType="Solid" Appearance-FillStyle-MainColor="Transparent"
            Appearance-Border-Visible="false">
        </PlotArea>
        <ChartTitle>
            <Appearance Position-AlignedPosition="Top">
            </Appearance>
            <TextBlock Text="Outstanding Requests Summary">
            </TextBlock>
        </ChartTitle>
        <Legend Visible="True">
            <Appearance Visible="True">
            </Appearance>
        </Legend>
    </telerik:RadChart>

Hi Daniel,

Generally, you can customize the label location manually by setting the SeriesItem.Label.Appearance.Distance property like this:

ASPX:

<telerik:RadChart ID="RadChart1" Skin="Simple" DefaultType="Pie" AutoLayout="True"
    Width="680px" Height="350px" runat="server" OnItemDataBound="RadChart1_ItemDataBound">
</telerik:RadChart>

C#:

protected void Page_Load(object sender, EventArgs e)
{
    RadChart1.DataSource = new double[] { 1, 2, 3, 4, 5, 6 };
    RadChart1.DataBind();

    RadChart1.Series[0].Appearance.ExplodePercent = 50;
}

protected void RadChart1_ItemDataBound(object sender, ChartItemDataBoundEventArgs e)
{
    if (e.SeriesItem.Index == 4)
    {
        e.SeriesItem.Appearance.Exploded = true;
        e.SeriesItem.Label.Appearance.Distance += 10;
    }
}

Hope this helps.
