Polar diagram in a clockwise with qwtpolarplot

[stepner03]

I need to display a polar diagram in a clockwise direction with the 0 upwards.
(Use the object qwtpolarplot) I also read on the forum "http://www.qtcentre.org/threads/61839-qwtpolar-plot-clockwise"....ma unfortunately does not work.
Can someone help me ?
