tplot crashes while trying to plot some MAVEN data

[nickssl]

Two different problems, one in specplot.py the other in lineplot.py.

To reproduce the first error:

from pyspedas.maven.spdf import load from pytplot import tplot sta_vars = load(trange=['2020-12-30', '2020-12-31'], instrument='static', datatype='c0-64e2m') print(sta_vars) tplot('bkg')

To reproduce the second error:

swe_vars = load(trange=['2014-10-18', '2014-10-19'], instrument='swea') print(swe_vars) tplot('diff_en_fluxes')

The first (specplot) issue may have been fixed now, after Jim M's recent pytplot changes. With the latest version of pytplot, I get no errors (but the plot is blank?).

I'm still getting an error for the second case (which is also probably supposed to be a specplot...it's no longer trying to plot it as lines). But it's a different error:

['diff_en_fluxes']
Traceback (most recent call last):

    coordinate_to_plot = da.attrs['plot_options']['extras']['spec_dim_to_plot']
KeyError: 'spec_dim_to_plot'

I think this is also due to Jim's recent changes. Maybe we need to set this option in cdf_to_tplot? Is there a good default, or can we figure out what it needs to be in cdf_to_tplot?
