Item Value Appear on MouseOver?

[Nick Jones]

On a standard bar chart the item's value sits on top of the bar (see pic).  That's fine if you have a lot of space.  Does anyone know how or if it's possible to have the item value popup when the mouse is moved over the item.  Same can be said for the spleen mode and some of the over chart types in fact,

Hi Nick Jones,

You can use the Activeregion.ToolTip property of the Chart Series to show the item label on mouse hover like this:

for (int i = 0; i < RadChart1.Series[0].Items.Count - 1; i++)
     {
         RadChart1.Series[0].Items[i].ActiveRegion.Tooltip = RadChart1.Series[0].Items[i].YValue.ToString();
     }

I hope this is hepful!

All the best,

Thanks,

Exactly what I was after.  In case anyone in the future wants it in VB.

Private Sub RadChart1_MouseHover(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadChart1.MouseHover
     Dim i As Integer
     For i = 0 To RadChart1.Series(0).Items.Count - 1
         RadChart1.Series(0).Items(i).ActiveRegion.Tooltip = RadChart1.Series(0).Items(i).YValue.ToString()
     Next
 End Sub
