Different dataGrouping with the same x-values

[pawelfus]

Example: http://jsfiddle.net/fwcjnvqr/

Both data sets use the same x-values as base, but different dataGroupings are applied ( currentDataGrouping.count 6 vs 8). As the result, we have unsynchronized points in a shared tooltip.

Second example: http://jsfiddle.net/fwcjnvqr/3/

Now one series has applied dataGrouping and don't have it. Steps to recreate issue:

• show column series
• click on navigator to change extremes
• hide column series
• show column series

Works fine in 4.2.x
