QwtBarChart Start from Nonzero

Is there a good way to modify the Y-interval for the rectangle parameters of the QwtColumnSymbol for QwtBarChart so that the bars could be fixed from a nonzero such as 10 or -5?

I do not necessarily need a floating barchart, where each bar has its own unique start and stop locations, but that would also work for my application.

Thanks!

Maybe: barChart->setBaseline( ... ) ?

Thanks! I think that is what I needed.
