Enable unrotated axis ticks

DESCRIPTION

What does your feature request improve on? Please describe. According to some research, rotated axis ticks are much harder to read than rotated ones. Would appreciate, if there's an option to unrotate them as well as a setting to change the default behavior.

Describe the solution you'd like Create an option tickrotate/notickrotate and a corresponding setting to change its default value.

Additional context Add any other context or screenshots about the feature request here.

ANALYSIS

Depending on the result of the "U" option of the axis, this can be solved with that. If possible, there can be a corresponding option for that. If the "U" option does not resolve the issue, we won't fix the problem for now.
