Awesome Graphs shows statistics basing on emails contributor use when commiting changes to the repository. Sometimes one contributor can use different emails which can lead to inconsistent and incomplete data shown by Awesome Graphs.

To address this problem you can:

Use .mailmap in the repository

Starting from Stash 2.5.0 you can use the .mailmap file in your repository to merge several emails for one user. Only contributions made after you edited the .mailmap file are affected. Similarly, if you add the .mailmap file to your repository, it will take effect only for new contributions.

Use aliases in the user profile settings

To merge emails for contributions made before the .mailmap was edited or added, you need to specify these emails in Manage Account - Email addresses for each user. You can add as many e-mails as you want, only if they are not used by other Stash accounts.
