When I run this script
from scipy import *
from matplotlib.matlab import *
def f(x): return 2*x**3-5*x
x=(arange(2001)-1000)/100.0
plot(x,f(x))
axis([-10,10,-20,20])
show()
plot(x,f(x))
axis([-2,2,-5,5])
show()
I get an odd placement of the zero on the
x axis in the second plot. If I cut out
the first plot, this does not happen.
How am I causing this?
Thank you,
