Multipanel plot does not respect uparams unless it reads a a status file

[sealauren]

I passed the following to multipanel plot:

fig = MultipanelPlot(post,epoch=2454833,show_rms=True,yscale_auto=True,phase_ncols=2,phase_nrows=ceil(npl/2.), phasetext_size='small',saveplot=os.path.join(outdir,figdir,"%s_multipanel.png"%system),uparams=post.uparams).plot_multipanel(nophase=False)

where

post.uparams {'per1': 0.0, 'tc1': 0.0, 'secosw1': 0.0, 'sesinw1': 0.0, 'k1': 0.3, 'per2': -3.6e-15, 'tc2': 0.0, 'secosw2': 0.0, 'sesinw2': 0.0, 'k2': 0.31, 'dvdt': 0.0, 'curv': 0.0, 'gamma_harpsn': 0.27, 'jit_harpsn': 0.21, 'gamma_j': 0.43, 'jit_j': 0.26, 'tp1': 0.0, 'e1': 0.0, 'w1': 0.0, 'tp2': 0.0, 'e2': 0.0, 'w2': 0.0, 'mpsini1': 0.41, 'a1': 7.6e-09, 'musini1': 1.4e-06, 'rhop1': 0.83, 'mpsini2': 1.6, 'a2': 4.3e-07, 'musini2': 5.4e-06, 'rhop2': 0.79}

and

In [11]: post.maxparams Out[11]: {'per1': 0.837491225, 'tc1': 131.57500000018626, 'secosw1': 0.0, 'sesinw1': 0.0, 'k1': 2.6, 'per2': 45.29422297, 'tc2': 138.67900000000373, 'secosw2': 0.0, 'sesinw2': 0.0, 'k2': 2.22, 'dvdt': 0.0, 'curv': 0.0, 'gamma_harpsn': 0.57, 'jit_harpsn': 2.58, 'gamma_j': -0.55, 'jit_j': 3.6, 'tp1': 131.36562719393626, 'e1': 0.0, 'w1': 0.0, 'tp2': 127.35544425750372, 'e2': 0.0, 'w2': 0.0, 'mpsini1': 3.59, 'a1': 0.0168191516, 'musini1': 1.19e-05, 'rhop1': 6.2, 'mpsini2': 11.6, 'a2': 0.24053546, 'musini2': 3.84e-05, 'rhop2': 4.9}

The behavior I expected was for the plot to display a value and error for msini of each planet (as provided in the posterior object). However, the multipanel plot did not include information about my provided parameters and errors. This appears to be because multipanel explicitly only plots P, K, and e at first:
print_params = ['per', 'k', 'e'] units = {'per': 'days', 'k': plot.latex['ms'], 'e': ''}
which can only be augmented by reading in the MCMC chains (assuming a status file correctly pointing to the chains is provided in the expected location):
if hasattr(self.post, 'derived'): chains = pd.read_csv(self.status['derive']['chainfile']) # This is the line where multipanel assumes there is a status file in a particular location, but this is only generated via the CLI self.post.nplanets = self.num_planets dp = mcmc_plots.DerivedPlot(chains, self.post) labels = dp.labels texlabels = dp.texlabels units = dp.units derived_params = ['mpsini'] for l, par in enumerate(derived_params):

a possible fix is to also pass a "params" dict to multipanel plot, which could include derived parameters
