Difference between Two Code Scans for same branch

I am using Sonarqube 9.6 Version. I want to know is there any way that if I have scanned my code on master branch with little changes and I want to see the difference between these 2 scans. How can that be achieved?
Please let me know

You can find the history of measures in the Activity tab of your branch.

Hi Colin,

Thanks for letting me know

Could you please tell me is there any way that I can get these difference using Apis in workflows and how can I change the Start period of the NewCode?

Thanks

With regards to the API – check out this guide:

With regards to the New Code Period – you can go to Project Settings > New Code to look at your options for setting the new code period.
