[Bug] - Comparison of data vs. previous year (2023) #22370

Open jgbdkook opened 2 months ago

jgbdkook commented 2 months ago

What happened?

Hello everyone ! When I want to compare data for a period from 1 January 2024 to 30 June 2024 with the previous year, the period compared is from 26 December 2022 to 02 July 2023. The comparison automatically adds 7 days to the graphs. I checked without comparison and when I enter a date in 2023 the problem is similar. The application period is from 01 January 2023 to 30 June 2023 but the period displayed is from 26 December 2022 to 02 July 2023.

Usually I don't have any problems with the dates, but I don't know whether it's a date bug or a graph bug and whether the data is correct.

Thank you for your help

Thank you @jgbdkook for creating this issue 🙌

There are three 'Compare to' options and what you have described sounds like the compare to 'Previous Period'. But, what it sounds like you are trying to do is compare to 'Previous Year'. Could you please try your comparison again using the compare to 'Previous Year' option and let us know if you are still facing the same issue? Thank you!
