XamChart tooltip, can this be set to come over on a mouse click instead of a mouse over? If so, is there a code sample for this?
I think this will be problematic. The chart uses WPF's native ToolTipService to display tooltips, and normally you can handle ToolTipOpening event with a combination of Mouse events to control when the tooltips are shown, but I believe that clicking the mouse effectively cancels the tooltip, and WPF won't attempt to show the tooltip again until you leave the source UIElement and re-enter it.
