Hi
I want my plot to be visible when I display some text over it. Why
doesn't this work?
fig = plt.figure(figsize=(5,5), dpi=100)
ax=fig.add_axes([0.1,0.1,0.8,.8])
ax.hist(data)
box1 = TextArea("Minimum: %f" % mind, textprops=dict(color="k"))
box2 = TextArea("Maximum: %f" % maxd, textprops=dict(color="k"))
box = VPacker(children=[box1,box2],
align="center",
pad=0, sep=5)
anchored_box = AnchoredOffsetbox(loc=3,
child=box, pad=0.,
frameon=True,
bbox_to_anchor=(0.8, 0.72),
bbox_transform=ax.transAxes,
borderpad=0.,
)
art=ax.add_artist(anchored_box)
art.set_alpha(0.5)

Mathew,
Could you please include a completely self-contained version of the script for us to try out? Plus, which version of matplotlib are you using?

Thanks, Ben, but I figured out that I just needed to use
frameon=False. This way, I can see teh plot under the text.
Thx

Those artist in offsetbox module (e.g., TextArea, VPacker,
AnchoredOffsetbox) are mostly a container object, i.e., actual drawing
is done by other artists. And changing the artist attributes of the
container object often does not work.
In your case (I guess you want to make the frame translucent?), the
actual artist responsible for drawing the frame is anchored_box.patch
(==art.patch). So
anchored_box.patch.set_alpha(0.5)
should work.
