[Matplotlib-users] pylab plot problem

[Oğuz Y. <ogu...@gm...>]

I didn't understand why i can not see 20 dots with the below command,
but i just see 3 dots at the graph.

import pylab as P
import numpy as N


a1 = N.ndarray(shape=(10,2))*2

x = a1[:,0]
y = a1[:,1]

a2 = N.ndarray(shape=(10,2))+10
xx = a2[:,0]
yy = a2[:,1]

n_x = N.append(x,xx)
n_y = N.append(y,yy)

P.scatter(n_x, n_y, alpha=0.5)
P.xlim(xmin=n_x.min()*10, xmax=n_x.max()*10)
P.ylim(ymin=n_y.min()*10, ymax=n_y.max()*10)

P.plot(n_x, n_y, 's', alpha=0.7, ms=3)

P.show()


Normally i have 20 different points to be plotted but because they are
so close values it just plots three of them. Any idea how i can fix
it?
