Bar threshold resets after chart reflow when stacking is enabled

[stpoa]

Expected behaviour

After clicking reflow, resizing window or hiding and showing series chart should look the same as before (have the same bar threshold).

Actual behaviour

After clicking reflow, resizing window or hiding and showing series bar threshold equals 0.

Live demo with steps to reproduce

1. click reflow button.

Internal note
I think that it is more complex issue related with area stacking which has influence on column.

I observed a few issues:

• problem is caused by hardcoded cum = 0 in the Stacking.js part.

Line stacks[type][i].cum = 0; in the Axis.prototype.resetStacks

• http://jsfiddle.net/2a4ox4d5/ -> update series.color breaks stacking
• http://jsfiddle.net/n6rte075/ -> threshold for area seems to working strange
