Binding xamChart control to an ObservableCollection using the Object data provider:

1. Create a Microsoft® Windows® Presentation Foundation Window project.

2. Create a Resource section in your Window and add an Object data provider to it.

In XAML:

...
<Window.Resources>
 <ObjectDataProvider x:Key="PatientData" ObjectType="{x:Type local:PatientBusinessLogic}" MethodName="GetPatients" />
</Window.Resources>
...

At this point, you have everything in place to retrieve data. Now we can create a xamChart control and bind it to data using the Object data provider above.

In XAML:

...
<igCA:XamChart x:Name="Chart1">
 <igCA:XamChart.Series>
  <igCA:Series Label="Patient Height" ChartType="Column" DataSource="{Binding Source={StaticResource PatientData}}" DataMapping="Label = Name; Value = Height" />
  <igCA:Series Label="Patient Weight" ChartType="Column" DataSource="{Binding Source={StaticResource PatientData}}" DataMapping="Value = Weight" />
  <igCA:Series Label="Patient Systolic A.P." ChartType="Column" DataSource="{Binding Source={StaticResource PatientData}}" DataMapping="Value = SystolicPressure" />
  <igCA:Series Label="Patient Dyastolic A.P." ChartType="Column" DataSource="{Binding Source={StaticResource PatientData}}" DataMapping="Value = DiastolicPressure" />
 </igCA:XamChart.Series>
</igCA:XamChart>
...

Run the project to see a visual representation of the data in the collection.

You can also check the Data Binding Objects sample in the sample browser for complete example.

Please, could you give me more info about cross hair? Would you like to use it for data points?

Please
