What is wrong?

Hi

There are a couple of errors here. You really should be using the animation feature provided with Iris rather than the one built-in to matplotlib. Try this:

import iris
import iris.quickplot as qplt

from iris.experimental.animate import animate
import matplotlib.pyplot as plt

fname1 = 'qwumgla_pb000'
cubes = iris.load(fname)

kb = cubes[3]
pkb = kb[0, 19, :, :]  # I think this might be wrong

cube_iter = pkb.slices(('longitude', 'latitude'))
ani = animate(cube_iter, qplt.contourf)
plt.show()

Remember that you need to have more than one latitude-longitude slice in order to animate it. I suspect you might want something like:

pkb = kb[:, 19, :, :]

Let us know if you still have problems.

Also, see the documentation here http://scitools.org.uk/iris/docs/latest/iris/iris/experimental/animate.html for further reference.

Thank you for answer.

Suggests the same error code.

Example, could the same thing?

 

Thanks.

This problem is solved but I forgot to reply to the group. There was a follow-up question, pasted below. I don't work at the Met Office so I can't help, but I'm sure some one who does will get back to you.

Can I ask a few more?
