Plan about responsive charts

Hello,

Is there any plan about reponsive charts?
They could behave like an image: fluid width and auto height and auto redraw on page resize.

Maybe some info here (see "Going responsive – a flexible chart" part near the end of the page).
As I've understood, it seems the chart needs to be redrawn on window resize (better: at the end of resizing to avoid performance penalty) but I can't find where to call that draw() function.

Thanks
