I try to take artists from one subplot instance and add them to
another:
-------------------------
from matplotlib.backends.backend_agg import FigureCanvasAgg as FigureCanvas
from matplotlib.figure import Figure
from matplotlib.patches import Patch, Rectangle
from matplotlib.lines import Line2D
fig = Figure()
canvas = FigureCanvas(fig)
ax = fig.add_subplot(111)
ax.add_patch(Rectangle((.5, 1.5), 1, .2))
fig2 = Figure()
canvas2 = FigureCanvas(fig2)
ax2 = fig2.add_subplot(111)
for artist in ax.get_child_artists():
if isinstance(artist, Line2D):
ax2.add_line(artist)
elif isinstance(artist, Patch):
ax2.add_patch(artist)
ax2.add_patch(Rectangle((1.5, 2.5), 1, .2, facecolor='r'))
ax2.set_aspect("equal")
ax2.autoscale_view()
w, h = fig2.get_size_inches()
xmin, xmax = ax2.get_xlim()
ymin, ymax = ax2.get_ylim()
xext = xmax - xmin
yext = ymax - ymin
if xext < yext:
w = h * xext/yext
else:
h = w * yext/xext
size = fig2.set_size_inches(w, h)
canvas2.print_figure('copy2.eps')
-------------------------
But this fails to plot the first rectange in the resulting plot. The
second, red rectangle is painted correctly in the resulting plot, but
the first one is totaly missing in the plot, leaving only a line in
the plot. Is there some kind of internal status that has to be
resettet in the actors?
Kind regards
Berthold
