Applying theme to RadChart does not work for Line / Area series definition: Category: ParserError Message: System.Windows.Markup.XamlParseException: [Line: 0 Position: 0] ---> System.Windows.Markup.XamlParseException: Failed to assign to property
The Chart overrides the Colors from the ApplicationTheme no matter of the Theme set through SetTheme method. Ticket ID: 431553.
Area fill is not set correctly when IsZeroBased is false. This is visible when LinearGradientBrush is used.
DateTime-specific group descriptors (ChartMonthGroupDescriptor, ChartYearGroupDescriptor, etc.) not working with nullable DateTime field type. You can work around this issue by using plain ChartGroupDescriptors instead. For example if you wanted to use ChartMonthGroupDescriptor, you can achieve the same effect by exposing the Month field of the DateTime> as a int? read-only property on your business object, and then you will be able to properly group by the newly created integer field.
Having SeriesItemLabel custom style (style2) based on another style (style1), style1 is ignored. REASON FOR DECLINATION This is supported out-of-the-box by the new RadChartView (use the LabelDefinitions property of the series).
Provide access to RadChart in ItemTooltipOpening/Closing event.
Cannot change the ChartLegendItem style run time through the LegendStyle property of RadChart and the LegendItemStyle property of ChartLegend.
Case: Live data scenario in which data comes from the left with step 0.2. The labels should be with step 10 and show only integer labels like this: 0, 10, 20, 30, 40, etc. If the min data at the beginning of the chartarea is 0.6 for example the first label REASON FOR DECLINATION This is supported out-of-the-box by the new RadChartView (use the TickOrigin property of the axis).
When KeepExtremes sampling function is used, EmptyPointBehavior.Gap and EmptyPointBehavior.Drop settings are ignored and points appear as if EmptyPointBehavior.Zero is used.
The options how RadChart draws the pie/doughnut slices need to be extended - there should be a clockwise and anticlockwise direction. REASON FOR DECLINATION This is supported out-of-the-box by the new RadChartView.
In Charts with many Y-Axis, it would of great help to link the interaction features of the series with the Y-Axis it is mapped against, basically dimming/hiding the other Y-Axis. It would make it easier for users to find the Axis the series belongs to.
Two DataSeries with one DataPoint each where the YValue is 0. The Label for the first one is set to custom string and the Label for the second one as white space string " ". As a result both labels do not appear.
StrokeDashArray property does not apply to GridLines.
