MS Chart in WPF, Setting the DataSource is not creating the Series
- by Shaik Phakeer
Hi All,
Here I am trying to assign the datasource (using same code given in the sample application) and create a graph, only difference is i am doing it in WPF WindowsFormsHost. due to some reason the datasource is not being assigned properly and i am not able to see the series ("Series 1") being created. wired thing is that it is working in the Windows Forms application but not in the WPF one.
am i missing something and can somebody help me?
Thanks
