Delegate plotting to `FunctionData`

jwallwork23 commented 4 months ago

Now that we have FunctionData and its subclasses, it makes sense to move both the VTU and the matplotlib plotting functionality to these classes.

Parent issue: #26.

My feature request for the pyplot part would be:

add choice between tricontour, tricontourf, tripcolor
add option to triplot on top
allow passing kwargs to the axes objects (which would be set by ax.set(**ax_kwargs)) - for custom axis limits etc.
add option to plot every i-th subinterval (default 1, but useful when we have a lot of them)
similarly to above: plot every i-th exported timestep

For the last two, I'd probably like to again stride backwards so we always plot the final one. Although having the first one would be nice too...

Thanks for the input @ddundo, this is really useful. Anything else to mention from you, @acse-ej321?

As agreed, I assigned this to myself :)
