Hi,

I've dug around the forums but haven't had much luck in finding any information related to this.  We use the WPF XamDataChart to gather incoming data and are trying to find a way to have two sets of marked points.  I haven't found a lot of information in the 

First set: These are makers that reside on the axis line.  Their purpose is to mark a point in time that some event happened.  These are placed by users clicking a button elsewhere.  This happens as the chart is being updated.

Second set: These are markers that reside on a chosen series.  They are points selected by a user, and are placed via clicking on a line at a given point.

My best guess as to how to implement this is to simply create a secondary set series that are scatter-point series that has some overhead logic to plot the points.  But if there is a simpler way (or any way, in the case of binding a marker to the axis) I would love to see!  Thanks!
