Hi Firedrakers,

I've been trying to follow the Camassa Holm example to use matplotlib, but I get the following error:

firedrake:WARNING Cannot plot figure. Error msg: 'Unsupported Functionality'

Is it because of the DG space or have I missed something else?

Hi Will, we currently don't support plotting of vector fields, only scalar fields, which is why you get this error. It would not be difficult to add the functionality, but we have not done so. Patches welcome. Cheers, Lawrence
