  hi,
  
  I'm reading a column from a Excel file including time data with hh:mm:ss format.
  I couldn't show them properly using RadChart in X-Axis. I've used the following code:
  
  

  radChart.DefaultView.ChartArea.AxisX.IsDateTime = true;

  radChart.DefaultView.ChartArea.AxisX.Step = 5;

  radChart.DefaultView.ChartArea.AxisX.LabelStep = 2;

  radChart.DefaultView.ChartArea.AxisX.StepLabelLevelCount = 3;

  radChart.DefaultView.ChartArea.AxisX.StepLabelLevelHeight = 10;

  radChart.DefaultView.ChartArea.AxisX.DefaultLabelFormat = "hh:mm:ss";

  
  in X-Axis it only shows 00:00 !?
  What's the solution?

  Hi Libertad,

  Please excuse us for the delay.
  
  Regarding your issue, the X axis makes all the needed range calculations and when there is data for the past several days it displays the steps as one day, therefore each tick is 00:00.
  
  You can use the following options.
  1. Use Categories. See the link below for more information:
  http://www.telerik.com/help/silverlight/radchart-features-categorical-charts.html
  2. You could also set the AxisX.AutoRange to false and pass only min, max and step parameters(i.e. AxisX.AddRange(min, max, step)).
  
  You can also find useful information about DateTime Support here:

  If you need any further help, please do not hesitate to ask.

  Hello Libertad,
  
  I attached a sample project that should be similar to yours. Please take a look at it and you may find it helpful.
  
  You can also refer to the following topics below.

  For security reasons zip attachments are not allowed in the public forums but you can open a formal support ticket and send us your sample application should you have further questions.

  Hi,
  Due to dynamic issue I have to configure my chart in code behind not xaml.
  I wonder if you do some changes in my sample to solve the problem instead of creating new sample from scratch.
  Thanks.

  Hi Libertad,
  
  I suggest that we keep the conversation in a single thread so that it is easier for both sides to follow it.
  
  I edited the project you've attached in the other thread started by you and attached it to this one.
  
  The reason why your values are displayed as 00:00 is because you've made new SeriesMapping instance in your for loop. At the end of the for loop, I simply added the following code:
  seriesMapping.ItemMappings.Add(itemMappingX);
