Hey!
Yeah, the activity graph can be a bit slow to update sometimes. Here's what's usually going on:
Normal delay - The contribution graph typically updates within a few hours, but it can sometimes take up to 24 hours to reflect recent activity. It's not real-time, so a bit of patience usually does the trick.
Things to check:

Email verification - Make sure the email address associated with your commits matches a verified email on your GitHub account. Contributions won't show up if there's a mismatch.
Commit authorship - Check that the commits in your PRs are actually authored by you (not just committed by you). You can verify this by looking at the commit details in the PR.
Repository type - Contributions to private repos only show up on your graph if you've enabled "Private contributions" in your profile settings (Profile → Edit profile → scroll down to Contributions & Activity).
Default branch - PRs need to be targeting the default branch (usually main or master) of the repository to count toward your contribution graph.

To force a refresh:
There's no manual refresh button, but you can try:

Hard refresh your browser (Ctrl+F5 or Cmd+Shift+R)
Check in an incognito window to rule out cache issues
View your profile from a different device

If it's been more than 24 hours and nothing's showing up despite checking all the above, there might be something specific going on with your account or repos. In that case, reaching out to GitHub Support would be your best bet.
Hope that helps!

The "activity overview graph" you're seeing could be one of two different things on GitHub: your personal profile's contribution graph or a specific repository's activity graph. Both can take time to update and have specific rules for what counts.

This is a common frustration. There isn't a manual "Refresh" button for the contribution graph; it updates automatically based on a strict set of rules. If your new Pull Requests (PRs) aren't showing up, they likely fail one of GitHub's specific criteria for counting contributions.

Here is a checklist to troubleshoot and force the activity to appear.

1. The "Fork" Trap (Most Likely Cause for PRs)

If you are contributing to someone else's project (Open Source), you likely forked their repository first.

• The Rule: PRs opened from a fork do not count immediately. They only count if and when they are merged into the original repository's default branch.
• The Fix: You have to wait for the maintainer to merge your PR. Once merged, the contribution will backdate to when you opened the PR.
• Exception: If you open a PR in a repository you own (not a fork) or have direct write access to (without forking), it counts immediately.

2. Check Your Git Email Identity

GitHub links commits to your profile using the email address in your local git configuration. If this doesn't match the email in your GitHub settings exactly, the graph remains blank.

• How to check: Run this command in your terminal:

git config user.email

• The Fix: Compare that output to the emails listed in your GitHub Settings > Emails. If they don't match:

1. Add the email from your terminal to your GitHub account settings.
2. The graph will automatically "refresh" and populate your past activity within a few minutes.

3. The "Default Branch" Rule

Commits are only counted if they happen on the default branch (usually main or master) or the gh-pages branch.

• The Scenario: You are working on a feature branch (e.g., feature/login-fix).
• The Fix: Your commits on that branch will not show up on the graph until that branch is merged into the default branch via a Pull Request.

4. Private Repository Visibility

If these PRs are in a private repository, your profile settings might be hiding them.

• The Fix:

1. Go to your GitHub Profile page.
2. Look for the "Contribution settings" dropdown (usually above the graph).
3. Select "Private contributions".
4. This forces the graph to redraw and include anonymized private activity.

5. The 24-Hour Delay

GitHub's background jobs sometimes lag.

• The Reality: If you just made the PRs (within the last hour) and everything else is correct, it might simply be a cache delay. It usually resolves within 24 hours.

I recommend checking your local email configuration first, as that is the most common silent error.
