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?
Hi Etienne,
Without your data I can only guess at what might be going wrong. One
guess is that you specified explicit values for the radial.lim argument
in the initial call and then did not do so in the "add" call. If you
don't want to send your data, try to create a fake data set that will do
the same thing. Then I could try to debug it.
Jim
