Plotting two solinst files consecutively with different level units doesn't work

[jnsebgosselin]

Running this script, where the files are from the tests folder located here:

filename = "2XXXXXX_solinst_levelogger_edge_testfile.csv"
reader = SolinstFileReader(osp.join(dirname, filename))

print(reader.sites)
print(reader.sites.instrument_serial_number)
print(reader.records.keys())

reader.plot()

filename = "2XXXXXX_solinst_levelogger_edge_testfile.lev"
reader = SolinstFileReader(osp.join(dirname, filename))

print(reader.sites)
print(reader.sites.instrument_serial_number)
print(reader.records.keys())

reader.plot()

Genereates the following traceback. Note that no error occurs if both dataset are plotted individually in a new namespace.

Traceback (most recent call last):
