    Hi I need help making a bar chart that will display a set for frequencies against the frequency strength from the radio receiver. I can't get the data from the radio receiver in real time so I need to data to be already inserted into the bar chart. 

    I was hoping to make something like the RadDomainDataSource example, where I would have a drop down menu that will give you the choice of choosing frequencies from 100 KHz to 200 KHz and another selection from 201 to 300 and so on. Selecting one of these would bring up the chart data. I was wondering how do you get the data so once you click it shows the right info.

    Have you prepared the chart already? Are you showing anything in the chart? If so - when the user selects something from the menu - you will need to prepare the new items source for the chart and then pass it to the ItemsSource property. 

    The full source code for the RadDomainDataSource sample can be found under your local installation path. For example - C:\Program Files (x86)\Telerik\RadControls for Silverlight Q1 2012\Demos.

    Feel free to contact us again if you have any specific questions.

    All the best,
