How control whether text & plot elements can go beyond EDGE of plot?

If you want to clip to the axes bounding box, you either need to set
clip_on when the text instance is created

  text(x,y,s, clip_on=True)

or later if you have an existing text instance 't' you can set the clip
bounding box manually

  t.set_clip_box(ax.bbox)

Your second method that referred to bbox *worked*!!!

# ------------------------------------------------------
from pylab import *
fig = Figure()
p = fig.add_subplot(111)
plot([1,2,3])
t = text(0, 2.2, "Hello", horizontalalignment = 'center')
t.set_clip_box(p.bbox)
show()
# ------------------------------------------------------

The first method did *not* for some reason!?!? :frowning:

# ------------------------------------------------------
from pylab import *
plot([1,2,3])
text(0, 2.2, "Hello", horizontalalignment = 'center', clip_on = True)
show()
# ------------------------------------------------------

I would prefer to make the second method work because it lets me avoid
having to define a Figure object /explicitly/ as above. The problem
with adding a subplot to a Figure object is that that many defaults
change that I would have to fix. (e.g. grid lines disappear, plot
dimensions are altered in strange way, etc.)

How fix second way to avoid a Figure object?
