Use MouseMove event to display x and y axis position in c#

[Layzie292]

I am trying to display the x and y axis position whenever a user moves the mouse over the graph.  it will update a text box.  I tried to use the mousemove event but i only get the location of the mouse and not the x and y value.  What do i use to get those values.  Thanks

Hi Layzie292,

You can use the InverseMapDataPoint method as shown below:

private void mouseMove(object sender, MouseEventArgs e)
{
   double xData, yData;
   Point p = new Point(e.X, e.Y);

   waveformGraph1.Plots[0].InverseMapDataPoint(waveformGraph1.PlotAreaBounds, p, out xData, out yData);

   textBox1.Text = xData.ToString();
   textBox2.Text = yData.ToString();
}

If you don't have that method (I can't remember which version first introduced it), refer to this post. 

Best Regards,

That worked great
