A NullReferenceException is thrown when the Strategy of the series is set Available in LIB version: 2017.2.605
The exception can be observed when you a plot data point with value that falls outside of the range of the Decimal type. As a workaround you can coerce the data before give it to the chart.
The exception is reproducible when the chart contains series with RenderOptions=Direct2DRenderOptions. The error message is: HRESULT: [0x8876086A], Module: [SharpDX.Direct3D9], ApiCode: [D3DERR_NOTAVAILABLE/NotAvailable], Message: Unknown
Currently, if the trackball position is outside the plot area boundaries, the element is not clipped and there is no mechanism that allows clipping it. Note: The trackball is the small ellipse that snaps to the data points.
Allow to track points that intercept vertical line from mouse position (as now) or points that intercept horizontal line from mouse position. So allow to choose TrackDirection = Horizontal/Vertical Thanks. marc.
Add mechanism for getting the layout slot of the axis
Possible positions: - above or below the X axis - left or right of the Y axis
Some of the data points plotted in the chart are not positioned as expected in a scenario with DateTimeContinuousAxis with SmartLabelsMode=SmartStep and PlotMode=OnTicksPadded or BetweenTicks.
PlotArea occasionally stops refreshing in live data scenario with asynchronous updates (multithreading).
When a System.Windows.Interactivity.EventTrigger is attached to a ChartTrackBallBehavior a XamlParseException is thrown. A possible work-around for this would be to set the CommandParameter to be the parent collection of the behavior and not the behavior itself.
Add support for millisecond sampling interval to ChartDataSource.
Implement ChartSeriesLabelDefinition properties as DependencyProperties
Numeric axes should be able to specify their PlotMode as categorical axes do (currently numeric axes use hardcoded OnTicks plot mode).
Add support for BoxPlot series type either through enabling extensibility of the CandlestickSeries type, or through providing new built-in BoxPlot series type.
Extend ChartSelectionBehavior to support continuous range selection through drag&drop.
When this mode is on - all of the points for which information in the track ball is shown should be on the left hand side of the mouse.
