[Matplotlib-users] Annotation add_artist bug

[Ben A. <bax...@co...>]

When I try using axes.add_artist() to add an Annotation object, it does not work.  Adding a Text object in this manner works fine.  Shouldn't Annotation also work since it inherits from Text?  The sample code below demonstrates.  I am using version 0.98.3.

from matplotlib.pyplot import figure, show
from matplotlib.text import Text
from matplotlib.text import Annotation

fig = figure()
ax = fig.add_subplot(111)

text = Text(0, 0, 'This is Text')
ann = Annotation('This is an Annotation', (1, 1))
ax.annotate('This is another Annotation', (2, 2))

ax.add_artist(text)
ax.add_artist(ann) #this does not work

ax.set_xlim(-1, 5)
ax.set_ylim(-1, 5)
show()
