Stockchart missing the last point in navigator

[Quang]

I’m working with a stock chart that has a navigator, but I’m running into two issues:

1. The endpoints of the navigator are being cut off.
2. The time intervals on the navigator appear uneven, even though I’ve set the baseUnit to "minutes" and the baseUnitStep to 30.

I’m not sure what’s causing these problems. Any help would be appreciated! Thanks!
