Save plot 1D mesh

Asked by Anders Pettersson

Hi!
I have problems with saving my plots. It seems like I can't save them with the commands write_png, write_ps... when the mesh is one dimensonal. Is this correct? Is there any other way to save it? Parts of the code follows:

q = 1
W_h = FunctionSpace(mesh, "DG", q)

x_h = Function(W_h, x_h)
p = plot(x_h, title = "x_h", basename = "begynnelse50")
p.write_png("begynnelse50.png")

Thanks in advance!

I'm not sure this is a correct fix, but you can try to apply the following patch to viper.py (from Viper):

Johannes, if it works for you, just go ahead and apply the patch to
Viper so we don't forget about it.
