How to remap all negative and positive value in 0 to 1 scale in polar plot?

Hi,

I am wondering how to remap all positive and negative values into 0-1 scale in polar plot?

The values I have look like:

from 0 to 1/2 pi, r=0.5,

from 1/2 pi to pi, r= -0.2

from pi to 2/3 pi, r= -0.3

from 2/3 pi to pi, r=0.1,

without remapping, the negative value will go to the opposite region (i.e. the value -0.2 supposed to be in 1/2 pi to pi region but will map in the opposite region 3/2 pi to pi,

so I want to remap all values, including negative and positive values, into 0-1 scale, so that all value will stay in their assigned region.

Is there any way to do it?

Thanks,

Cece

 r = [0.5 -0.2 -0.3 0.1];
 r = r - min(r);
 r = r/max(r);
