When I update the c3.js version I used from 0.7.1 to 0.7.10.
I find the issue about zoom function.
In 0.7.10, I zoom the chart, the line is displayed correct,
but the mouse cursor can not positioning correctly on the point in the chart.
As attached file, I zoom in the chart, then I move mouse on one point, but point displayed is the other one.
