High zoom chart has sudden change in x-axis

Was trying to see chart like this:

<img width="697" height="493" alt="Image" src="https://github.com/user-attachments/assets/50c7d5d3-ba2f-4fb5-b447-97e1fc87e982" />

Then it suddently changed to this:

<img width="692" height="515" alt="Image" src="https://github.com/user-attachments/assets/ebe6438c-5ef7-4f12-8115-46587617762b" />
