Hi, I am having a hard time adding a figure from ica.plot\_properties() into a mne.report, here is the error : ```python AttributeError Traceback (most recent call last) in 54 with mne.open_report(f_report) as rep: 55 rep = mne.Report(image_format = 'svg', title = subject) ---> 56 rep.add_figs_to_section(figs = ica_figs, captions = ica_captions, section = 'ICA plotting') 57 rep.save(f_report, open_browser = True, overwrite = True) 58 rep.save(f_report[:-2]+'html',open_browser = True, overwrite = True) ~/.virtualenvs/py3.6/lib/python3.6/site-packages/mne/report.py in add_figs_to_section(self, figs, captions, section, scale, image_format, comments, replace) 1110 img_klass = self._sectionvars[section] 1111 -> 1112 img = _fig_to_img(fig, image_format, scale) 1113 html = image_template.substitute(img=img, id=global_id, 1114 div_klass=div_klass, ~/.virtualenvs/py3.6/lib/python3.6/site-packages/mne/report.py in _fig_to_img(fig, image_format, scale, **kwargs) 72 elif not isinstance(fig, Figure): 73 from .viz.backends.renderer import backend, MNE_3D_BACKEND_TESTING ---> 74 backend._check_3d_figure(figure=fig) 75 if not MNE_3D_BACKEND_TESTING: 76 img = backend._take_3d_screenshot(figure=fig) AttributeError: 'NoneType' object has no attribute '_check_3d_figure' ``` Here is the code to reproduce the error as well as the raw data used (\>100Mo), you can directly see the outputs and the error in the Jupyter Notebook version : [reportError\_code.zip - Google Drive](https://drive.google.com/file/d/1FAeag4_5rr4jlcS5ANpOC0oZo3u14Y3X/view?usp=sharing) It seems to me that the report function can’t display a figure with multiple axes like ica.plot\_properties(), if I just add an ica.plot\_scores or plot\_components figure with only 1 axe in the report it works fine (example also included in the provided code). Also displaying the figure directly outside of the report works fine. I can’t figure it out why it displays an error related to a 3D figure but trying to solve this with mne.viz.set\_3d\_backend(“notebook”), and replacing notebook by pyvista or mayavi but none worked… Setting matplotlib to qt instead of inline as recommended for Linux users won’t work… I also tried updating to the last mne, matplotlib and Ipython version, didn’t work neither… I am running out of ideas and it seems nobody ever encountered the same problem so if you have any clue I would appreciate !

Hello @apoublan, in principle, adding ICA property plots to the report **should** work; in fact, we’re doing that in the MNE BIDS Pipeline, producing reports like this: [http://mne.tools/mne-bids-pipeline/examples/ERP\_CORE/sub-015\_ses-ERN\_task-ERN\_proc-ica\_report.html](http://mne.tools/mne-bids-pipeline/examples/ERP_CORE/sub-015_ses-ERN_task-ERN_proc-ica_report.html) However, we don’t use SVG and we only add one property plot at a time. I can have a look at your code later. Best wishes, Richard ---

Hello @richard, Thanks for the report example ! I tried in PNG too, same problem and in the example I sent you there is only one EOG component identified so one property plot at a time. Thanks a lot, let me know. Best wishes Arnaud ---

`ICA.plot_properties()` returns a **list of figures.** The following MWE based on you code & data works for me: ```python # %% import mne fname = './S01-raw.fif' raw = mne.io.read_raw_fif(fname, preload=True) n_components = 0.98 raw_ica = raw.copy().pick_types(eeg=True).filter(l_freq=1, h_freq=40) ica = mne.preprocessing.ICA(n_components=n_components, method='picard', random_state=11) ica.fit(raw_ica) ica_captions = [] ica_figs = [] ica_figs.extend(ica.plot_properties(raw, picks=[0, 1])) ica_captions.extend(['property 1', 'property 2']) report = mne.Report(image_format='svg') report.add_figs_to_section(section='ICA', figs=ica_figs, captions=ica_captions) report.save('/tmp/foo.html', overwrite=True) ``` ---

Hi Richard, I could have a look at your fix, indeed the use of the extend method instead of append to add the list of figures returned by ica.plot\_properties worked out, thank you ! Best, Arnaud
