**plot\_sensors\_connectivity()** Hi, I have a question about plot\_sensors\_connectivity(). Can I save the figure somehow or/and make subplots? I don’t need 3D figure, so I just need jpg or png picture. Thanks! ---

The function returns a Matplotlib figure instance. So something like ```python from mne_connectivity.viz import plot_sensors_connectivity fig = plot_sensors_connectivity(info, con, ...) fig.set_size_inches(desired_width, desired_height) fig.savefig('my_figure.png') ``` should work. If that doesn’t work, it’s a bug, please let us know. ---

Unfortunately it’s not working: ```python --------------------------------------------------------------------------- AttributeError Traceback (most recent call last) Input In [26], in ----> 1 fig.savefig('my_figure.png') AttributeError: 'PyVistaFigure' object has no attribute 'savefig' ``` ---

`plot_sensors_connectivity()` returns a 3D scene, so saving it to disk is a little bit more complicated. Here’s a fully reproducible working example: ```python # %% import mne from mne_connectivity import spectral_connectivity_epochs from mne.datasets import sample from mne_connectivity.viz import plot_sensors_connectivity import matplotlib.pyplot as plt data_path = sample.data_path() raw_fname = data_path / 'MEG/sample/sample_audvis_filt-0-40_raw.fif' event_fname = data_path / 'MEG/sample/sample_audvis_filt-0-40_raw-eve.fif' raw = mne.io.read_raw_fif(raw_fname) raw.info['bads'] += ['MEG 2443'] picks = mne.pick_types(raw.info, meg='grad', eeg=False, stim=False, eog=True, exclude='bads') events = mne.read_events(event_fname) event_id, tmin, tmax = 3, -0.2, 1.5 # need a long enough epoch for 5 cycles epochs = mne.Epochs(raw, events, event_id, tmin, tmax, picks=picks, baseline=(None, 0), reject=dict(grad=4000e-13, eog=150e-6)) fmin, fmax = 4., 9. sfreq = raw.info['sfreq'] # the sampling frequency tmin = 0.0 # exclude the baseline period epochs.load_data().pick_types(meg='grad') # just keep MEG and no EOG now con = spectral_connectivity_epochs( epochs, method='pli', mode='multitaper', sfreq=sfreq, fmin=fmin, fmax=fmax, faverage=True, tmin=tmin, mt_adaptive=False, n_jobs=1 ) # %% # Do the actual plotting connectivity_fig = plot_sensors_connectivity( epochs.info, con.get_data(output='dense')[:, :, 0] ) # Take a screenshot of the 3D scene screenshot = connectivity_fig.plotter.screenshot() # The screenshot is just a NumPy array, so we can display it via imshow() # and then save it to a file. fig, ax = plt.subplots(figsize=(10, 10)) ax.imshow(screenshot, origin='upper') ax.set_axis_off() # Disable axis labels and ticks fig.tight_layout() fig.savefig('connectivity.png', dpi=150) ``` ![connectivity](https://global.discourse-cdn.com/free1/uploads/mne/original/2X/3/35f22634449400fcc57bba2b221f2ad02cb2828b.jpeg) ---

@richard, thank you very much! ---

would it be possible to save the returned 3D scene as an interactive 3D pdf file? ---

I’m afraid this is currently not possible, sorry.! ---

Thank you for your reply. Alternatively, it is possible to export the 3D scene as a glTF file ([export\_gltf — PyVista 0.37.0 documentation](https://docs.pyvista.org/api/plotting/_autosummary/pyvista.Plotter.export_gltf.html)) and view it with an online viewer ([https://gltf-viewer.donmccurdy.com/](https://gltf-viewer.donmccurdy.com/)). ---

how did you do this? Because I have been having errors all day ---

@codZeus please open a new issue, and provide code for a minimal, reproducible example, and the error (including full traceback) you encounter when running that example in a fresh python session. ---

sure I will. I asked a question about whitened evoked response and whitened GFP that hasn’t been answered. Do you mind helping me with that? Thanks ---
