Hello,
I have 2d array with fourier amplitudes that I would like to plot. I
found two options: contourf and imshow. This is my code:
omega = np.fft.rfftn(b_field, axes=(1, 0))
omega = np.abs(np.fft.fftshift(omega, axes=(1,)))
fig = plt.figure()
ax = fig.add_subplot(111)
M =
Did you try to change vmin, vmax?

If this is not what you want, please describe more explicitly why the
colorbar is wrong.
Regards,

Hi,
I want the colorbar to show the real fourier amplitudes, not the
amplitudes after rescaling to 0..1. In other words: the colorbar created
by imshow should have the same values as the one created by contourf.
I am not sure how I can use vmin and vmax to achieve that effect. The
scaling is
I think I'm lost.

But, in your original post, your plotting two different image.
with contourf, you're drawing omega*1, but with imshow, you're
drawing omega.
Are you saying that
Hi,
Believe it or not, the factor of 1 was my only problem all the time.
Until you pointed it out I never noticed that it was missing in one of
the calls.
Thanks!
