Is it necessary to disable dragging when it's not fully zoomed out ?

[aelam]

I've read the wiki and also wrote a demo about this.
I've found when the chart is not fully zoomed out, I can't use drag-to-highlight feature
I think it's a bit weird.
If the chart data is on the most left, [0,1,2,...], and then we swipe a finger from left to right, it will be pretty cool and normal if it still can highlight data .

Same as ScrollView
super scrollView embeds subScrollView. if subScrollView can't scroll more, the super ScrollView can continue scrolling

Enabling / Disabling highlighting

setHighlightPerDragEnabled(boolean enabled): Set this to true on your Chart to allow highlighting per dragging over the chart surface when it is fully zoomed out. Default: true
