Setting tick number manually shall not change them when reautoscaling

1. setting a specific number of ticks
2. doing a autoscale, zooming or whatever

Expected: the number of ticks do not change

Current: the number of ticks changes

Idea: Adding a checkbox if the ticknumber shall be automatic or manually. By default it is set to automatic, but when the user types numbers manually it should turn off
