Custom Tooltips in Stacked Bar charts

Sep 26, 2013 at 10:14 PM
I'm brand new to WPF and I'm trying to add custom tooltips to a Stacked bar 100% series chart. I've tried setting the Series definition tooltip property:

this.InProcess.ToolTip = "Customer Name";

But that doesn't work. The default value is still shown. Is there a simple way of adding custom tooltips? One that doesn't require creating a custom template, etc, etc, etc?
