 Hello

I try to create a polar.plot in order to represent some paths. I have one
more information: the signal quality.
I created classes and I used the argument "add" to superimpose my
different signal
levels.

the result:

Normally, the hotter spots should follow the green path. Despite this, we
can see that the shape of the paths are the same for hot spots but on a
smaller scale.

I think that polar.plot with "add" argument ignores the scale of the active
plot. I saw that by changing the radius scale (elevation angle). With 0° at
the center, I have the same polar.plot.

But I don't know how to fix it. Have you any ideas?

Thank you


Etienne
