> unless I put the set_ylim() command _after_ plot(). Why?
Quoting myself from my first post in this thread
1) you are calling set_ylim before a plot command and the autoscaler
is kicking on the plot command and overriding your changes. You
should call set_ylim after all plot commands, or turn autoscaling
off with the autoscale_on property of the Axes
