[Matplotlib-users] grid of subplot

[Gabriele B. <gb....@gm...>]

Hi,
I'm trying to follow this example to make a grid of subplot:

http://matplotlib.org/examples/pylab_examples/line_styles.html

but my code plot the two rows in two different figures (i attach them but I
don't know if they are useful). Does anyone understand why?

this is an extract of my code:

alphas = [45, 75]
numalp = len(alphas)

angles = np.linspace(pi/12, pi/2, num=10)
numobs = len(angles)

axisNum = 0

for a in alphas:

          #[some operations]

          for obsangl in angles:

                       #[some operations]

                       axisNum += 1
                       axii = plt.subplot(numalp, numobs, axisNum)
                       plt.errorbar(g, Pgamma, yerr = ePgamma, color =
'green', fmt = '.')
                       axii1 = axii.twinx()
                       plt.plot(g, lightcurva, 'b-')
                       axii.set_yticklabels([])
                       axii.set_xticklabels([])
                       axii1.set_yticklabels([])
                       axii1.set_xticklabels([])
