For Chart with ScatterLineSeries, in case the ItemsSource contains points with following sample horizontal values: 0, 2, 4, 6, 8, 6, 4, 2, 0, ZoomBehavior does not work correctly on iOS - when ZoomMode is set to "Both", the points are taken in incorrect order and the result is a zig-zag chart.

X-Axis labels are overlapped when new data points are constantly added.
on Android, the axis labels are replaced.
There is an inconsistency in the behavior on Android and iOS.
Workaround:
apply ChartPanAndZoomBehavior and set
PanMode to "Horizontal"
ZoomMode to "Horizontal"
And chart Zoom to "2,1"
<telerikChart:RadCartesianChart PaletteName="Light"
Zoom="2, 1">
<telerikChart:RadCartesianChart.BindingContext>
<local:ViewModel/>

While using the trackball feature some axis labels are disappearing. While trackball is activated with tap and hold, dragging down makes the bottom label on the y-axis disappear and dragging left makes the first label on the x-axis disappear.

Bar series disappear when applying zoom and then pan
The behavior can be reproduced in a horizontal bar series:
The vertical axis is categorical, and the horizontal axis is numerical
<telerik:RadCartesianChart.ChartBehaviors>
<telerik:ChartPanAndZoomBehavior PanMode="Vertical"
ZoomMode="Both" />
</telerik:RadCartesianChart.ChartBehaviors>
<telerik:RadCartesianChart.VerticalAxis>
<telerik:CategoricalAxis />
</telerik:RadCartesianChart.VerticalAxis>
<telerik:RadCartesianChart.HorizontalAxis>
<telerik:NumericalAxis Minimum="0"
ShowLabels="True"
LabelFormat="N0">
</telerik:NumericalAxis>
</telerik:RadCartesianChart.HorizontalAxis>
<telerik:RadCartesianChart.Series>
<telerik:BarSeries CategoryBinding="Category"
ValueBinding="Value"
ItemsSource="{Binding Data}" />
</telerik:RadCartesianChart.Series>Workaround:
Replace the axis:
Use categorical axis for the horizontal axis and numerical axis for the vertical axis

Hello,
I am using Telerik RadCartesianChart to display 5 different series. As per requirement, I need to use a secondary vertical Axis for the 5th series. I followed https://www.telerik.com/forums/multi-axes-chart-xamarin-ios to achieve that. But if I bind data after a delay then it's not working for iOS.
Steps:
1. Bind series data after delay.
For more details please refer attached files.
I look forward to your reply!
Regards,
Ajay Dodiya | Sr. Xamarin Developer

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.

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
