DOLFIN

scale plot

Asked by Melanie Jahny

I'd like to plot the solution of my equation (its navier-stokes)
but my mesh is quiet thin and very large (it's 2D). So it would be more
clear if I could scale the y-axis in a different scala than the x-axis.
Is there any possibility in FEniCS to do that? Perhaps there are any
parameters for the plot-command?

mesh = Rectangle(0,0,155,0.78, 155, 10)
u = TrialFunction(VectorFunctionSpace(mesh, "CG",2))
 ....
plot(u, title="Velocity", rescale=True, axes=True)

It would be great if there was any possibility to do that.
Thanks for any help!

if you export your solution(s) to Paraview VTK files (.pvd), you can
read them in in Paraview and make plots and scale the axes independently.
