    We have a RadMap with an information layer containing Pie RadCharts. They work fine untill you plot many of them.

    We are trying 100 and it seems to take 7 second to plot the items.  When we replace them with Component Ones C1Chart, the performance is much improved, this is disapointing.

    Below is the code, are we creating the chart in the best manner?



    <Telerik:RadMap x:Name="VisualisationMap"













    ="{Binding SelectedVisualisationLayer.Map, Mode=TwoWay, Converter={StaticResource MapToProviderConverter}}"

                                                   Utilities1:RadMapHelper.BestView="{Binding Path=BestView, Mode=TwoWay}">


                        <Telerik:InformationLayer Name="ItemsLayer" ItemsSource="{Binding Path=SelectedVisualisationLayer.MapItems}">





                                    <Telerik:RadChart Background="Transparent" BorderThickness="0" Height="100" Width="100" IsHitTestVisible="False" Telerik:MapLayer.Location="{Binding Path=Well.Location, Mode=TwoWay, Converter={StaticResource LocationConverter}}" >






                                                        <Telerik:PieSeriesDefinition ShowItemLabels="False" ItemStyle="{StaticResource PointChartSlice}">


                                                                <Telerik:InteractivitySettings HoverScope="Item" SelectionScope="Item" SelectionMode="Single" />






                                                    <Telerik:ItemMapping FieldName="SelectedPointChart.Value" DataPointMember="YValue" />






                                                    <Telerik:ChartDefaultView >


                                                            <Telerik:ChartArea Margin="0" Padding="0" Background="Transparent"/>



                                                            <Telerik:ChartLegend Visibility="Collapsed"/>



                                                            <Telerik:ChartTitle Visibility="Collapsed"/>

    Hi Patrick,

    Basically, it is the Silverlight framework that limits the number of visuals that can be displayed simultaneously. On the other hand, RadChart has been designed for lots of features and fancy looks and this comes at a price. Each chart requires a certain number of visuals rendered and multiplying this by  100 starts to challenge the framework.

    Now, that we have shipped RadChartView, I would suggest giving it a try in this situation. It is much lighter and you should be able to see a significant performance boost for the same number of charts. You can find an extensive comparison between RadChart and RadChartView here: RadChart vs RadChartView.

    Best regards,
    the Telerik team
