Fix bar size issue on traffic tab

[irfano]

Fixes #20335

This fixes the incorrect bar height issue on the traffic tab.

• Removed granularity as it was necessary for the zoom feature, which we don't use. 8394773
• Set min-max values for the left axis since the data depends on the left axis. 10bbe8e

Regression Notes

1. Potential unintended areas of impact

   • None

2. What I did to test those areas of impact (or what existing automated tests I relied on)

   • N/A

3. What automated tests I added (or what prevented me from doing so)

   • This issue is caused by the settings of a 3rd part lib for the chart. It's not proper to add UI tests for this minor issue.

Works for me. The numbers are slightly higher. Could could have changed since it's today. But not to the degree it was before. Could you double check you also see the view increase? Merge if it looks good. Good work.
