Hello list,

I have plotted the following curve:

from pylab import *

t = arange(0.0, 2.0, 0.01)

s = sin(2*pi*t)

plot(t, s)

grid(True)

show()

The std matplotlib output gives only zoom, pan and save functions. I

need to check the distance between two points on the plotted curve by

clicking on the curve. How do I do this?

Thanks,

AMaity
