When a chart have long labels on the X axis (like date and time) the zoom is not accurate on the horizontal extents with both mouse wheel and drag area.
The reason is probably that the screen coordinates of the selected area are not mapped correctly on the X axis. The mapping works fine for tooltip.
You can verify this behavior in the attached Solution. In the images you can see the selected area (01), that the zoomed area is a region with no points (02) and the actual position of the points.
Add support for BoxPlot series type either through enabling extensibility of the CandlestickSeries type, or through providing new built-in BoxPlot series type.
Gaps appear between the bars in the stacks when the series are populated with negative and positive values. Check the attached picture. If you have a scenario with mixed values (positive and negative) use RangeBarSeries instead of BarSeries.
I would like the possibility to change the color of a line depending on the value.
I have values between -1 to 10.
If the value is -1 I would like the color (or possible the opacity) to change until it goes back to 0 or above.
Issue1) When no RenderTransformOrigin is set to ScaleAnimation, all slices should be scaled from the pie chart center point. Currently thiss is not true, to better reproduce it , set MaxScale > 1 and notice slices overlap each other at the end of the animation.
Issue2) When RenderTransformOrigin is set to , for example (0, 0), all slices should start animating from topleft corner of the chart. Currently only the first one is animated from top left and all others are animated from pie chart center.
An InvalidCastException is thrown in the Fill/Background property binding in the series' DefaultVisualStyle when the RenderOptions is set to Bitmap or Direct2D.
Make the StepLineSeries being able to plot a 'step' for a single point. Currently the StepLine series does not support drawing a single data point when it is in the beginning or the end of the ItemsSource.
It appears the ChartView is also affected by the same SharpDX issue that affected the RadWebCam when it is used over Remote Desktop.
A simple test of any series will replicate the issue. If it is being used via Remote Desktop, the series will not render.
" Collection was modified; enumeration operation may not execute.'" - The exception is observed when the CLR exceptions are enabled from Visual Studio.
The Ellapsed event handler of the Timer is executed in background thread but modifying chart data in a background thread is considered bad practice which is not supported by our component. This is the reason we are declining this bug report.
General solution is to schedule the data update to happen on the UI thread with Dispatcher. When in ViewModel, the following code can be used:private void OnTimerElapsed(object sender, ElapsedEventArgs e)
