How does squashing, rebasing, reset --soft affect github contributions page?

Solution 1:

I saw this still here so I figured I might as well answer the question. So the answer is YES. It will remove the contributions from the graph. It won't do it right away because commits that are no longer being pointed to by anything can technically still be reached for awhile but are eventually garbage collected and thus removed from your contributions page.

Solution 2:

The reference page is "Why are my contributions not showing up on my profile?"

Commits will appear on your contributions graph if they meet all of the following conditions:

• The email address used for the commits is associated with your GitHub account.
• The commits were made in a standalone repository, not a fork.
• The commits were made:
  • In the repository's default branch (usually master)

So if your rebase affect commits in master, chances are your contribution page would reflect that.
