[Matplotlib-users] Ovality of a perturbed circular path

[Nils W. <nw...@ia...>]

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
