When the Chart is zoomed, new labels are not rendered on iOS.

When the series data is updated and axis labels are redrawn, occasionally the default DateTime format is shown in DateTimeContinuousAxis.

Loading Chart on iOS raises an exception of type InvalidCastException.

If customers set bindings to these properties and try to set range from negative to positive values (e.g. from -0.5 to 0.5) the bindings are not applied as expected.

If you have a Chart with BarSeries and TooltipBehavior defined, the tooltip of each bar is shown only when the user taps in the area around the tip of the bar.

The expected behavior is the tooltip to be displayed when clicking anywhere on the bar.

When you set custom stroke to ScatterLineSeries, the colors in the RadLegend are not updated.

When you have some Series defined and dynamically clear and add new Series, those are not displayed correctly on iOS - it seems the vertical axis is not extended, and all the data points are visualized on the horizontal axis.

Setting SelectedPointOffset and RadiusFactor in DonutSeries or PieSeries causes unexpected behavior when selecting a pie piece in the chart.

Once the data of the bar chart is changed, the selection behavior does not fire. The issue is reproducible when the chart is placed inside AnimationPanel,

The issue seems to be down to the width - either calculated or set. Some widths seem to cause the lines to appear - refer to the attached chart_grey_lines.png file.

Workaround: manually calculate the screen width upon load and to set the width to a corresponding lookup value

SelectionChanged event of the Chart SelectionBehavior is not raised for LineSeries when DataPointSelectionMode is "Single" and  SeriesSelectionMode is "None".  

If we have a Chart with combined barseries and lineseries, and the lineseries is added first, the bars are misaligned - they are not placed in the center of the axis label on Android.

As a workaround, make sure to add first the barseries, then the lineseries.

When Custom Palette is used and FillColor is set, the color is not applied to the line series.

As a workaround set the both properties of the PaletteEntry: FillColor and SrtokeColor: 

<telerikChart:PaletteEntry  FillColor="Red" StrokeColor="Red" />

StrokeColor and Labels colors are not properly mapped in native Chart.

The iOS Chart raises an exception when null values are added at runtime

When navigate to page with ScrollView and charts through PushAsync method and its animation option is true, the ScrollView freezes.

Navigation.PushAsync (new ChartsPage (), true); // ScrollView freezes

Workaround:

Navigation.PushModalAsync (new ChartsPage (), true); // ScrollView does not freeze
Navigation.PushAsync (new ChartsPage ()); // ScrollView does not freeze

Two of the bar series used CombineMode="Stack" and one - CombineMode="Cluster". The BarSeries with CombineMode="Cluster" overlaps the series with CombineMode="Stack".
