Hi,

I am using xamDataChart which has two line series with CategoryDateTimeXAxis and NumericYAxis. I have enabled crosshair over chart and I want to show both Series values in a tooltip with crosshair.

I find a reference here to show the tooltip with cross hair but it is not showing me any Series Value where vertical line of crosshair is. Here is the image what I am getting.

I am using the same code which Graham suggest in his post but as show in screen shot, Value is empty.

Here is my complete XAML code of the view if it may help.
