Hi all,

I would like to visualize the ovality of a perturbed

circular path by a polar plot.

How can I improve the view wrt to scaling and ticks ?

from pylab import linspace, polar, xticks, yticks, show, savefig, subplot, figure

from numpy.random import rand

from numpy import ones, exp, pi, r_

theta = linspace(0.,2*pi,25)

r = 20.*ones(24)

r = r_[r,r[0]]

noise = 2.*rand(24)-ones(24)

noise = r_[noise,noise[0]]

figure(1)

polar(theta,(r+noise))

figure(2)

polar(theta,(r+noise)/r)

show()

Any pointer would be appreciated.

Nils
