Hi,

I am plotting an MSChart from an observable collection. I am also having a datagrid whose itemsource is the same collection.
Now when I select a row/item in the datagrid, I want to display a label with the selcted x,y value near to the same point in my chart. I tried a lot but found no way. I can place label correctly only if i get screen coordinates of my selected data point. I have to fix this issue quickly.

Thanks
Nishitha

Hi Nishitha,
Can you please be more clear about your question?
Where are you putting your datagrids?
I have one possible solution, according to my understanding.
try this:
private void MSChart1_GetToolTipText(object sender, ToolTipEventArgs e)
{
DataPoint dP = MSChart1.Series["Series1"].Points[(int)MSChart1.ChartAreas["ChartArea1"].AxisX.PixelPositionToValue(e.X)];

e.Text = "SelectedDatapointLabel = "+ MSChart1.Series["Series1"].Points[dP.XValue].AxisLabel +" SelectedDatapointValue = "+dP.YValues[0].ToString();

}

Try in your own way. This is my method. If I could understand your question, I could write here more clearly.

Note: The above function is an Event, given in MSChart (ToolTip Event). You can also use MouseMove Event.
