Binding pie chart to timebar

[Ray White]

Is there a way to bind a RadPieChart to a TimeBar?

The RadChart has a nice TimeBar property that can be used to display only the data selected by a RadTimeBar.  Nice!  But I don't see this for RadPieChart.  Here's how I bind to RadChart:

 

<telerik:RadChart.TimeBar>

    <Binding ElementName="timeBar1" />

</telerik:RadChart.TimeBar>

<telerik:RadChart.SeriesMappings>

    <telerik:SeriesMapping>

        <telerik:ItemMapping DataPointMember="XCategory" FieldName="TimeStamp" />
        <telerik:ItemMapping DataPointMember="YValue"    FieldName="Value1" />

    </telerik:SeriesMapping>
</telerik:RadChart.SeriesMappings>

 

 

Optionally, could I bind the RadPieChart to the RadChart?
Or, could I make the RadChart display as a pie?

I think I found the answer.  You can change a RadChart to a pie style with this:

 

<telerik:RadChart.DefaultSeriesDefinition>

    <telerik:PieSeriesDefinition ShowItemLabels="False" />

</telerik:RadChart.DefaultSeriesDefinition>

I wish there was a simple wizard to handle all this.  You can't right-click on the silverlight chart control and get a wizard.  Instead, you seem to have to write code like this.  Uggh...

Hello Ray,

RadChart supports other series as well as pies and bars. You can specify the series definition in your mapping as it is described in this topic in our help system. Here is some code:

<telerik:RadChart.TimeBar>
    <Binding ElementName="timeBar1" />
</telerik:RadChart.TimeBar>

<telerik:RadChart.SeriesMappings>
    <telerik:SeriesMapping>
        <telerik:SeriesMapping.SeriesDefinition>
            <telerik:PieSeriesDefinition />
        </telerik:SeriesMapping.SeriesDefinition>
        <telerik:ItemMapping DataPointMember="XCategory" FieldName="TimeStamp" />
        <telerik:ItemMapping DataPointMember="YValue"    FieldName="Value1" />
    </telerik:SeriesMapping>
</telerik:RadChart.SeriesMappings>
