Hi Uwe, and everybody,

I'm using a QwtPolarSpectrogram as a RADAR or SONAR PPI,it works faily well and is a great tool, thanks for this, btw.!!

The thing is: I only need the "upper half" of the widged (0-180° of the polar circle). Is i t possiblie to only show the upper half? Any Ideas about this?


Thank you!
