All,
I am curious why this doesn't work:
# linebuilder.py
import matplotlib.pyplot as plt
class LineBuilder:
def __init__(self, line):
self.line=line
self.xs=list(line.get_xdata())
self.ys=list(line.get_ydata())
self.cid=line.figure.canvas.mpl_connect('button_press_event', self)
def __call__(self, event):
print 'click', event
if event.inaxes != self.line.axes:
print event.inaxes
print self.line.axes
return
self.xs.append(event.xdata)
self.ys.append(event.ydata)
self.line.set_data(self.xs, self.ys)
self.line.figure.canvas.draw()
fig=plt.figure()
ax=fig.add_subplot(111)
ax.set_title('click to build line segments')
line, =ax.plot([0], [0])
plt.show()
linebuilder=LineBuilder(line)
However, if I put the plt.show() on the last line, it works. Can anyone explain?
David.
