I have the following chart declared in XAML:
In the code behind I have:
When I attach a collection to the ItemsSource property, everything updates dynamically (the collection implements INotifyPropertyChanged) except the YValue. The bubbles move along the x-axis and changes size when the underlying collection changes, but they won't move along the y-axis when value_1 changes in the collection.
Have I forgotten something obvious or are there any limitations to this?
| <telerik:RadChart x:Name="Bubble" Width="160" Height="160" VerticalAlignment="Center" Margin="20,0,0,0" Visibility="Collapsed"> |
| <telerik:RadChart.SeriesMappings> |
| <telerik:SeriesMapping> |
| <telerik:SeriesMapping.SeriesDefinition> |
| <telerik:BubbleSeriesDefinition BubbleSizeRelative="False"/> |
| </telerik:SeriesMapping.SeriesDefinition> |
| <telerik:SeriesMapping.ItemMappings> |
| <telerik:ItemMapping DataPointMember="XValue" FieldName="value_0"/> |
| <telerik:ItemMapping DataPointMember="YValue" FieldName="value_1"/> |
| <telerik:ItemMapping DataPointMember="BubbleSize" FieldName="value_2"/> |
| </telerik:SeriesMapping.ItemMappings> |
| </telerik:SeriesMapping> |
| </telerik:RadChart.SeriesMappings> |
| </telerik:RadChart> |
In the code behind I have:
| Bubble.DefaultView.ChartArea.AxisX.AutoRange = False |
| Bubble.DefaultView.ChartArea.AxisY.AutoRange = False |
| Bubble.DefaultView.ChartArea.AxisX.MaxValue = 6 |
| Bubble.DefaultView.ChartArea.AxisX.MinValue = 0 |
| Bubble.DefaultView.ChartArea.AxisY.MaxValue = 6 |
| Bubble.DefaultView.ChartArea.AxisY.MinValue = 0 |
| Bubble.DefaultView.ChartArea.AxisY.AddRange(0, 6, 1) |
When I attach a collection to the ItemsSource property, everything updates dynamically (the collection implements INotifyPropertyChanged) except the YValue. The bubbles move along the x-axis and changes size when the underlying collection changes, but they won't move along the y-axis when value_1 changes in the collection.

If I rebind the chart the values update correctly - it's just the dynamic update of YValue that seems to be causing concern.

Additional update:
If I change the seriesdefinition to Line instead of Bubble everything seems to work. Both x and y-axis updates dynamically, so is this an issue with the bubble chart only (or are there some special conciderations)?

Hello Jorn,
Indeed we must confirm that this is a bug that is specific to the Bubble series type. We have logged this issue in our public issue tracking system and it will be addressed for one of the next releases of the control.
We have updated your Telerik points for the report as well.
Sorry for the temporary inconvenience.
