[Solved] Date Formatting in DateTimeContinuousAxis

[Andy Macourek]

I have a chart rendering based on my data, but I am having an issue with the date not formatting on the x-axis. If I do not apply formatting, the date shows as a full string, but I only want the hour and minute to show.  The XData datatype is DateTime.

<DataTemplate>
<telerik:RadCartesianChart Width="700" Height="200">
<telerik:RadCartesianChart.HorizontalAxis>
<telerik:DateTimeContinuousAxis LabelFitMode="None" LabelFormat="hh:mm" >
</telerik:DateTimeContinuousAxis>
</telerik:RadCartesianChart.HorizontalAxis>
<telerik:RadCartesianChart.VerticalAxis>
<telerik:LinearAxis/>
</telerik:RadCartesianChart.VerticalAxis>
<telerik:LineSeries ItemsSource="{Binding ChartData}">
<telerik:LineSeries.ValueBinding>
<telerik:PropertyNameDataPointBinding PropertyName="YData"></telerik:PropertyNameDataPointBinding>
</telerik:LineSeries.ValueBinding>
<telerik:LineSeries.CategoryBinding>
<telerik:PropertyNameDataPointBinding PropertyName="XData"></telerik:PropertyNameDataPointBinding>
</telerik:LineSeries.CategoryBinding>
</telerik:LineSeries>
</telerik:RadCartesianChart>
</DataTemplate>

The problem is that all the labels are just the string "hh:mm"

Hello, Andy 

Thank you for using our RadControls for Windows 8!

In order to achieve this result you have to use the following formatting pattern (following the String.Format routine):

LabelFormat="{}{0:hh:mm}"

More information may be found in this documentation article (LabelFormat property):

I hope this helps. If you have any further questions do not hesitate to contact us again.

All the best,
