Thank you for contacting us.
Indeed there is an issue where chart axis is not updated when the data has changed. I have logged it in our feedback portal
where you can track its status. I have also added telerik
points to your account as a token of gratitude for bringing this issue to our attention.
As a workaround, you can reset the chart axis to force the chart to update its data.
chart.Series.ItemsSource = GetCategoricalData();
Please, let us know if you have further questions.
