With Autoscale Y axis checked, models that do not vary by more than one or two integers only show 1 y-axis label. Should show 4 or 5 ticks.

1. Load Example 'Bistable model' from dropdown.
2. Check 'Autoscale Y'
3. Run simulation.
   Result:
   see attached screenshot.
   

Expected: Show 4 or 5 tick marks on Y axis with numerical values on the bottom and top tick marks at minimum
