Crash plotting empty HPCA energy spectra #492

Closed ericthewizard closed 1 year ago

ericthewizard commented 1 year ago

Plotting HPCA energy spectra for a time range when there's no data leads to an error:

import pyspedas
pyspedas.mms.hpca(trange=['2016-10-16/5:00', '2016-10-16/6:00'], datatype='ion')

from pyspedas.mms.hpca.mms_hpca_calc_anodes import mms_hpca_calc_anodes
mms_hpca_calc_anodes(fov=[0, 360], probe='1')

from pyspedas.mms.hpca.mms_hpca_spin_sum import mms_hpca_spin_sum
mms_hpca_spin_sum()

from pytplot import tplot
tplot('mms1_hpca_hplus_flux_elev_0-360_spin')

This should be fixed in pytplot-mpl-temp v2.1.43
