Chord diagram output - publishable resolution images

Hi MNE forum - I am using Connectivity_circle_trial.ipynb on men very 1.2.3.

I have two issues - one saving the output and 2 saving the output at sufficiently high resolution for publications ie 300dpi.

I have gone over the site and notice one reply ( it was brief and not very explanatory) about using mne.analyze to perform this.

Can someone please explain to a newbie (me!) how to otherwise save images at high enough resolution for my images!

Iā€™m pleased with the output Iā€™m getting and wish to share it with the wider world,

BW
