Discussion: Should this feature be called "axis breaking" or "axis collapsing"? This may probably depend on if I can implement break folding/unfolding feature.

I think the HighCharts implementation is quite tricky for the users. Although we can provide similar APIs with graphic.elements to enable developers do similar things, I'd prefer implementing such design as default axis broken style so that it won't be misleading to viewers if developers aren't very experienced in dataviz and don't know how to (or why should) let viewers understand this is an axis skipped some ranges.
