twinx() seems to blow up matplotlib when pylustrator switched on - 'AxesSubplot' object has no attribute 'collections'

[derketo]

Not sure how, but turning on pylustrator causes matplotlib error without any reference in stack trace to pylustrator. Presumably something is being overridden or set in pylustrator.start() which causes matplotlib behaviour changes which are causing this.

My code working fine without pylustrator (but could be refined :):

chart_some_data.py

# various other imports omitted

import datetime import matplotlib.dates as mpdts import pylustrator

#pylustrator.start() # works with this commented out

# ... omitted data collation, which creates w_dts and w_pps as identical length vectors # w_pps are floats, w_dts are floats from datetimes using mpdts.date2num() # ... fig, axs=plt.subplots(nrows=2, ncols=1) axs[0].plot(w_dts, w_pps) ax0_2=axs[0].twinx()

Uncomment the 'pylustrator.start()' line, and matplotlib blows up as follows (cannot get this editor to show the indents on the alternate code lines, sorry):

I cannot reproduce the error. Here it works fine. Maybe you can update to the latest version and try again. Maybe its a problem with the datetime objects. But then I would be grateful to have a full working minimal example.

As I did not receive feedback on how to reproduce this bug I will close the issue for now.
