Dynamically add LineSeries-derived type to QML ChartView

[cooked]

Hi,
I've created my MyLineSeries type which extends LineSeries adding some custom properties and methods.
Is it possible to have instances of MyLineSeries created dynamically and added to the series of a ChartView?
ChartView.ceateSeries unfortunately creates only predefined declarative types.

thanks in advance for the help
