[yt-users] How to get the np.array of profile plots

Hi, all, I am trying to use matlibplot to plot the profile of a sphere object, so I need to get the np.array of profile plots. I know that we can use "slc.frb" to get the np.array of SlicePlot. However, I don't find the simliar function in profile plots, how can I get the np.array of a sphere object's profile? Thanks a lot for every suggestion or help. best wishes, Yifeng He
