Shared horizontal crosshairs
When using a shared tooltip and horizontal crosshairs, the crosshair will only display on the first series drawn, if there is more than one. Even if the cursor starts out tracing along a different series, the crosshair is pinned to the first series drawn. Could this behaviour be modified so the crosshair is associated with the series the cursor is highlighting?
Workaround: use more crosshairs instead of showing for first series only, example: http://jsfiddle.net/jazrR/3/
