There are several threads in this forum about synchronizing the crosshairs/tooltip across multiple charts. For example, see this Fiddle. However, there are issues if the heights of the charts are different. See this Fiddle.
If the chart heights are the same, the crosshairs appear and disappear at the same time on both charts when moving the mouse cursor from top to bottom (or vice versa) over the charts. But this is not the case with different chart heights. Can you suggest a modification to the second Fiddle to make the crosshairs properly appear/disappear?
