Polar or cylindrical plot

[Shobhit Saheb Dey]

I have a superfluid simulation in cylindrical coordinates with theta and z in fourier basis while r in chebyshev basis. The simulation is running fine without any error, but I want to plot the density plots now(via a colormap). Even if I could plot just a cross section of my domain i.e a polar plot, it will be fine. Please guide me through.

This might be problematic in some cases. Is there any dedalus function to plot the fields in polar or cylindrical coordinates?

Hi Shobhit,

Since everyone usually wants to customize their plots in very specific ways, we only provide some very limited plotting tools (under dedalus.extras.plot_tools).  I’d recommend learning to use matplotlib or another python plotting package.  A good option could be to load the dedalus outputs into xarray and use their plotting features (http://xarray.pydata.org/en/stable/user-guide/plotting.html).

Best,

Thanks, Keaton, I have my code running anyway using matplotlib, I was just asking it from the uniformity point of view.
