Hi,
Thanks to @LorenzoStucchi the four Sen-ET graphs have been updated 
This should solve a number of issues as described in the pull request.
The easiest way to make use of the new graphs is to install the Sen-ET plugin (if you don’t have it already) and then replace the graphs located in
∼/.snap/auxdata/sen-et-conda-<OS>64/sen-et-snap-scripts/auxdata/graphs
by their equivalents from the GitHub repository.
