Hi! Lets suppose I have several series on a chart with different point intervals (or data passed as [x,y] values), and enable shared tooltip for it, like this: http://jsfiddle.net/phhm9/

When you move the mouse over the chart, the tooltip flickers with values for different series. This may be OK with such a simple example, but when you have lots of points that are not consistently present at the same time for each x axis value, the tooltip becomes unusable.

Is there a way to make the tooltip show all series values in this case, e.g. by interpolating absent values between closest points, or by always choosing the closest value for each time series?
