Hi all,
I have a script that reads in mouse-click coordinates from an image.
I noticed that, with image extents specified, the axes flip whenever I
plot to them.
This snippet demonstrates the behaviour I see:
# -- START --
import pylab as P
import numpy as N
# Generate test pattern
x = N.arange(100).reshape(-1,1) + N.zeros(100)
def click(event):
print "Mouse click at (%f,%f)" % (event.xdata,event.ydata)
P.plot([event.xdata],[event.ydata],'o')
P.draw()
P.imshow(x,extent=(0,x.shape[1],x.shape[0],0))
P.connect('button_press_event',click)
P.show()
# -- END --
Is this normal? If so, how do I get around the problem? I also
noticed that, even without extents, the image gets scaled after
plotting.
I'd appreciate any advice!
Thanks for your time.
Stéfan
