Hello, you helped me with an example of this on a Pie Chart. It worked for a while but has sporadically started throwing exceptions when the chart is clicked. Here is my code and the exception. Please help!private void chrtUnitsByProduct_MouseClick(object sender, HitTestEventArgs e) { if ((e.Point >= 0) && (e.Series >= 0) && (SDBox.SelectedValue != null)) { // Change third chart ItemsSource here using e.DataItemdProduct p = (dProduct)e.DataItem;if (p.Channel != "All Channels") { // MessageBox.Show(c.Channel);DataAccess dao; dao = ( DataAccess)App.Current.FindResource("dao");chrtUnitsByRegion.ItemsSource = dao.dGetDataByRegionForProductChannel((Int16)SDBox.SelectedValue, p.Product, p.Channel); // <TextBlock Text="{Binding Path=DataItem.channel}" Background="Transparent" Foreground="{StaticResource FontBrush}" FontWeight="Bold" FontFamily="Calbiri" FontSize="13" HorizontalAlignment="Center"/> TextBlock tb = new TextBlock(); tb.Text = "Channel: " + p.Channel + ", " + p.Product;tb.Background = Brushes.Transparent; tb.Foreground = ( LinearGradientBrush)App.Current.FindResource("FontBrush");tb.FontWeight = FontWeights.Bold;tb.FontFamily = new FontFamily("Calbiri"); tb.FontSize = 11; tb.HorizontalAlignment = HorizontalAlignment.Center; chrtUnitsByRegion.Titles[1].Content = tb; } } } System.ArgumentOutOfRangeException was unhandled Message="Index was out of range.

Hi, When I change the ItemSource of a chart in code the template is lost that I assigned in xaml. I'm using your Pie2 template and a few other tricks from other posts to apply lines and labels to the pie slices. <cfx:Chart Name="chart1" Gallery="Pie" ItemsSource="{Binding Source={StaticResource SpendByChannelProvider}}" BorderThickness="0" > <cfx:Chart.Titles> <cfx:Title HorizontalAlignment="Left" Margin="5"> <TextBlock Text="Total Marketing Expenses" Background="Transparent" Foreground="{StaticResource FontBrush}" FontWeight="Bold" FontFamily="Calbiri" FontSize="16" HorizontalAlignment="Left"/> </cfx:Title> </cfx:Chart.Titles> <cfx:SeriesAttributes BindingPath="Spend" Template="{StaticResource Pie2}"> <cfx:SeriesAttributes.PointLabels> <cfx:PointLabelAttributes Visibility="Visible"> <cfx:PointLabelAttributes.Template> <DataTemplate> <Grid> <Grid.RowDefinitions> <RowDefinition></RowDefinition> <RowDefinition></RowDefinition> </Grid.RowDefinitions> <Label Content="{Binding Path=DataItem.Channel}" Background="Transparent" Foreground="{StaticResource FontBrush}" FontWeight="Bold" FontFamily="Calbiri" FontSize="12"/> <WrapPanel Grid.Row="1" Orientation="Horizontal" IsHitTestVisible="False" > <Label Content="{Binding Path=DataItem.Spend, Converter={StaticResource fdc}, ConverterParameter='\{0:C\}'}" Background="Transparent" Foreground="{StaticResource FontBrush}" FontFamily="Calbiri" FontSize="9"/> <Label Content ="(" Background="Transparent" Foreground="{StaticResource FontBrush}" FontFamily="Calbiri" FontSize="9"/> <Label Background="Transparent" Foreground="{StaticResource FontBrush}" FontFamily="Calbiri" FontSize="9" HorizontalAlignment="Left" VerticalAlignment="Top"> <Label.Content> <Binding Path="Self" Converter="{StaticResource MyTooltipConverter}" ConverterParameter="%p" /> </Label.Content> </Label> <Label Content ="%)" Background="Transparent" Foreground="{StaticResource FontBrush}" FontFamily="Calbiri" FontSize="9"/> </WrapPanel></Grid> </DataTemplate> </cfx:PointLabelAttributes.Template> </cfx:PointLabelAttributes> </cfx:SeriesAttributes.PointLabels> </cfx:SeriesAttributes> </cfx:Chart> My chart initializes with default data from an ObjectDataProvider class also in xaml. Once the user selects what they want to see from a combobox, I load a new instance of the same class as I used for my ObjectDataProvider from the database and point the Chart ItemSource to it. The chart refreshes with the database data, (albeit not exactly right, but that's another post), then no longer has the template I assigned.DataAccess dao; // this is my database access object // MessageBox.Show(SDBox.SelectedValue.ToString());dao = (DataAccess)App.Current.FindResource("dao");chart1.ItemsSource = dao.dvGetSpendByChannel((Int16)SDBox.SelectedValue); chart1.AllSeries.Template = ( DataTemplate)FindResource("Pie2");Any Ideas? Thanks, Matt

Hello, I'm trying to achieve #2 above but I'm not clear how I should use Content and ContentTemplate properties of SeriesAttributes. I either get a Legend with the marker (pie slice) and no label, or a label with no marker. Please help.<cfx:Chart Name="chart1" ItemsSource="{Binding Source={StaticResource SpendByChannelProvider}}" Gallery="Pie" HorizontalAlignment="Left" Width="388.103" Grid.ColumnSpan="2" Margin="0,0,0,13" Grid.RowSpan="3"> <cfx:SeriesAttributes BindingPath="spend" Template="{StaticResource Pie2}"> <cfx:SeriesAttributes.PointLabels> <cfx:PointLabelAttributes Visibility="Visible"> <cfx:PointLabelAttributes.Template> <DataTemplate> <Label Content="{Binding Path=DataItem.Channel}" Background="Transparent" Foreground="Black" FontFamily="Calbiri" FontSize="12"/> </DataTemplate> </cfx:PointLabelAttributes.Template> </cfx:PointLabelAttributes> </cfx:SeriesAttributes.PointLabels> <cfx:SeriesAttributes.ContentTemplate> <DataTemplate> <TextBlock x:Name="BarText" Text="{Binding Path=DataItem.Channel}" HorizontalAlignment="Left" VerticalAlignment="Center"/> </DataTemplate> </cfx:SeriesAttributes.ContentTemplate> <cfx:SeriesAttributes.Content> <TextBlock x:Name="BarText" Text="{Binding Path=DataItem.Channel}" HorizontalAlignment="Left" VerticalAlignment="Center"/> </cfx:SeriesAttributes.Content> </cfx:SeriesAttributes> <cfx:Chart.LegendBox> <cfx:LegendBox> </cfx:LegendBox></cfx:Chart.LegendBox> </cfx:Chart>
