I'm not sure "make graphs for us" is a legitimate reason to share personal information (and email is considered personal information under GDPR). Error logs might be a bit different I suppose, if they are used to help resolve specific issues for your users, but even then I suppose one could argue that pseudo-anonymised data would be better than sharing an email address. I'm no GDPR expert, but that's my understanding of it.
