[Scilab-users] Problem graypolarplot

[SCHULZ Wolfgang]

Hello,
thanks this basically solves my problems with the presentation to north. I'm using Scilab 5.5.2 Win7 64 bit (sorry forgot to mention that in my original email) and the examples in my first email are according to the graypolarplot help page (graypolarplot(theta,rho,z,[strf,rect])). Maybe a bug in the help?

I still have some issues:
- As with the original function no data is displayed in the inner ring (see attached image 0-100km). The matrix contains 5x24 values but it seems not all of them are displayed. Is this a bug or am I doing something wrong?
- How do I tell the plot to colorize only values in a certain range? E.g. values are ranging from 20 to 140 and I want to colorize only from 50 to 150 from blue to red (jetcolormap).

Thanks for your help
Wolfgang
