sourcetree - How to understand git graph?

Question

As shown in the picture, how do you view the graph on sourcetre? I searched for an hour but couldn’t find any relevant articles

Answer 1

I know it may be too absolute to say this, so let’s understand it this way at the beginning

First of all, each line is a branch, and each point is a commit (submission record)

I think the leftmost one is the main trunk.

This means that a historical commit on the trunk is merged into the yellow branch -- git merge {sha}

This means that the contents of the yellow branch have been merged into the trunk -- git merge

This means a new branch is created from this point on the trunk -- git checkout -b

This means that the main content is merged into the new branch -- git merge

Build a repo by yourself, create a few more branches, and then come back to merge and rebase after modifications. You will understand after playing for a weekend
