Enhancement: Expose zoom to allow for programatically zooming

[Busteren]

Enhancement:

Say you have two different EventDrops charts with the same start and end dates. How would the best possible way to connect these charts be? I am looking into modifying the source (and make a PR if I figure it out) in order to do so, as I couldn't find a good way to do this initially.

Have anyone done this? If so some help is greatly appreciated :)
