As far I can see, I suppose you plot two axes on the same figure with twinx(). If you want to change the labels of the last created axis (in your case the line plot) than you can use the gca() shortcut (Get Current Axes) to set the label as follows:

fig1.gca().set_ylabel("Event probability")

The figure title can be set with:

fig1.suptitle("Hours to Event")
