Hi
I'm trying to track down an issue with the CocoaAgg backend on Mac OS
X using MacPorts, when run with the CocoaAgg backend the following
code:
from pylab import *
import time
ion()
tstart = time.time()
x = arange(0,2*pi,0.01)
line, = plot(x,sin(x))
for i in arange(1,200):
line.set_ydata(sin(x+i/10.0))
draw()
print 'FPS:' , 200/(time.time()-tstart)
fails with the backtrace:
$ python temp.py -dCocoaAgg
Traceback (most recent call last):
File "temp.py", line 2, in <module>
from pylab import *

globals(),locals(),[backend_name])
File

line 54, in <module>
class FigureCanvasCocoaAgg(FigureCanvasAgg):
File

line 63, in FigureCanvasCocoaAgg
start_event_loop.__doc__=FigureCanvasBase.start_event_loop_default.__doc__
NameError: name 'FigureCanvasBase' is not defined
However this runs without issue using the MacOSX backend:
$ python temp.py -dMacOSX
FPS: 20.1183278689
Is there some missing dependency that could cause this?
Cheers
Adam
