[Gnuplot-info] polar plot

[<dni...@gm...>]

Hi guys,

I have one question concerning polar plots. I want to plot wind direction
and concentration of dust in the air. Wind direction should be the degree of
the circle and the concentration of dust the distance from the center. I
made a example with excen (aargh!) but am not able to do this with gnuplot.
Can you give me a hint how to do this?

Thank you in advance!

Cheers
Daniel
