If a tooltip is already displayed in portrait orientation, rotating to landscape causes the tooltip to end up in a very wrong location.

The Chart loses all the UI customizations made in the iOS platform renderer when the Series are updated, for example, if you show/hide certain Series or updated their ItemsSource.

Annotation (Grid line ) for the DateTimeContinuousAxis is not visualized on iOS. It works as expected on Android.

Add grid line annotation for the datetime axes. the grid lines are not visualized on iOS.

Workaround: 
Use CategoricalAxis.

Currently on iOS the PanOffset is reset when the underlying data is updated, while the same behavior is not observed on Android.

When the tooltip is displayed at a certain data point and the data is updated from code-behind, the tooltip stays with wrong data. The expected behavior is the tooltip to be hidden in such case.

Hi Team,

If you set the PanOffset in XAML, it is not applied. 

Does not work:

<telerikChart:RadCartesianChart x:Name="MyChart"  Zoom="2, 1"  PanOffset="-400,0" >

I would expect that the RadChartView renderer would be responsible for handling this after the control is loaded and the series/axis is rendered (see workaround).

Workaround

If I subscribe to the ChartView's NativeControlLoaded event and wait approx 100ms before calling PanOffset, it will work.

e.g.

<telerikChart:RadCartesianChart x:Name="MyChart"  Zoom="2, 1" 
                                                     NativeControlLoaded="MyChart_OnNativeControlLoaded">

private async void MyChart_OnNativeControlLoaded(object sender, EventArgs e)
{
    await Task.Delay(100);
    
    MyChart.PanOffset = new Point(-400, 0);
}

Takeaway and Action Requested

The takeaway, and basis of this Bug Report, is that the control should internally perform this delay check and set the PanOffset.

This will enable MVVM scenarios because (I originally wanted to bind the PanOffset value from my view model).

Thank you,

Ramakant

A common scenario for the Chart is to have several Y-Axis, where some could be on the left, others could be on the right side of the Chart.

Currently RadChart provides only a ScatterPointSeries which does not support categorical axes and you can only use a numerical one.
