Is it possible to have the tooltip for a plot point on a line chart show only when the mouse is directly over that point on the x axis. If you look at the example link, when you hover over the first point, it shows the tooltip. However, the tooltip does not disappear as you move tho the right. When you get to the point that is in the gap, the tooltip bounces from the first point to the third depending on which side the mouse is on.
Is there a solution to this? The sparkline seems to do this correctly. When I hover over a gap on the sparkline, the tooltip disappears.
