ChartView with createSeries improved to define axis alignment

The method createSeries of a ChartView is the only way to create dynamic series but you can't specify the axis position. I've tried calling this method and then setting the 
axisYRight property but this action makes that the range of the other left axis takes the same values than the right axis.

The solution that I've found is modify the files declarativechart.cpp and declarativechart_p.h to specify the axis alignment.

If there are any other option to have series attached to left axis and other to the right I'm very interested.
