### Bug description When using Time comparison with cumulative post-processing, rows that exist only in the shifted period (e.g. 1 week ago) are lost if the current period has no data for the same day. This causes the cumulative curve to flatten (zero increment) on the current side and under-count on the shifted side. using resample does not fix the problem because it's on the postproccesing . ### Screenshots/recordings <img width="1246" height="745" alt="Image" src="https://github.com/user-attachments/assets/3bbc92f7-0025-4868-9bfd-f391dabfaf66"; /> ### Superset version master / latest-dev ### Python version 3.10 ### Node version 18 or greater ### Browser Chrome ### Additional context _No response_ ### Checklist - [x] I have searched Superset docs and Slack and didn't find a solution to my problem. - [x] I have searched the GitHub issue tracker and didn't find a similar bug report. - [x] I have checked Superset's logs for errors and if I found a relevant Python stacktrace, I included it here as text in the "additional context" section. -- This is an automated message from the Apache Git Service.
