I had this working in Silverlight about 2 years ago using a sample provided by Graham Murray but that sample does not seem to work the same in the WPF XamDataChart. Before I try to make the modifications to get this to work I wanted to see if anything has been added that enables this to work efficiently?
Right now it is implemented as a behavior that attaches when the mouse enters the chart, it takes the current x position of the mouse and translates that to a datetime based on the x-axis. Then for each series it find the closest element in the itemsource to that datetime and adds them to a collection thenthere is a separate behavior that displays that collection in a tooltip style. The only problem Ihad with this method is if there are a lot of points in each series the looping take a while and everything becomes choppy.
Is there a better way now?
Hello,
I am just checking if you require any further assistance on the matter.
I have been looking into your question and currently we do not provide such built-in functionality.
If you still need any further assistance on this matter, feel free to ask.
Here is the post I originally used to develop the solution:

Hello Mike,
I have been looking through your post and I am not completely sure how exactly is organized Graham’s sample application. Would you please attach it or give me a link to the forum thread where he has already attached it.
Looking forward to hearing from you.
