Force ylim range in subgraph - python-2.7

Question

When plotting a serie of subgraphs with matplotlib, I can't set the ylim range properly.
Here's part of the code:
import numpy as np
import matplotlib.pyplot as plt
import matplotlib as mpl
(...) # loading npy data
titles = ["basestr1", "basestr2", "basestr3", "basestr4", "basestr5"]
labels = ["baselab1", "baselab2", "baselab3", "baselab4", "baselab5"]
linew = 2.24
ms = 10
mw = 2
fc = (1,1,1)
bc = (1,1,1)
mpl.rcParams['axes.prop_cycle'] = mpl.cycler(color=[(1,0.4,0.4), (0.1,0.6,0.1), (0.04,0.2,0.04)])
mpl.rcParams.update({'font.size': 12})
fig2 = plt.subplots(2, 2, figsize=(12,9), facecolor=fc)
plt.rc('font', family='serif')
ax0 = plt.subplot(221)
ax1 = plt.subplot(222)
ax2 = plt.subplot(223)
ax3 = plt.subplot(224)
axl = [ax0, ax1, ax2, ax3]
em = []
fp = []
fn = []
gm = []
for c,element in enumerate(elements):
em.append([i[0] for i in element])
fp.append([i[1][1] if 1 in i[1] else 0 for i in element]) # red
fn.append([i[1][2] if 2 in i[1] else 0 for i in element]) # light green
gm.append([i[1][3] if 3 in i[1] else 0 for i in element]) # dark green
axl[c].semilogy(em[c], fp[c], "-x", lw=linew, markersize=ms, mew=mw) # red
axl[c].semilogy(em[c], fn[c], "-x", lw=linew, markersize=ms, mew=mw) # light green
axl[c].semilogy(em[c], gm[c], "-o", lw=linew, markersize=ms, mew=mw, mfc='None') # dark green
axl[c].set_ylim([-10, 200]) # <-- Here's the issue; it seems not to work properly.
axl[c].grid(True,which="both")
axl[c].set_title(titles[c])
axl[c].set_xlabel(labels[c])
axl[c].set_ylabel(r'Count')
plt.legend(['False', 'True', 'Others'], loc=3, bbox_to_anchor=(.62, 0.4), borderaxespad=0.)
plt.tight_layout(pad=0.4, w_pad=0.5, h_pad=1.0)
plt.savefig('/home/username/Desktop/figure.png',
facecolor=fig2.get_facecolor(),edgecolor='w',orientation='landscape',papertype=None,
format=None, transparent=False, bbox_inches=None, pad_inches=0.1,
frameon=None)
plt.show() # block=False
Where elements is a list containing 4 arrays.
Each of these array looks like:
elements[0]
Out[16]:
array([[1, {0.0: 1252, 1.0: 11, 2.0: 170, 3.0: 11}],
[2, {0.0: 1251, 1.0: 12, 2.0: 163, 3.0: 18}],
[3, {0.0: 1229, 1.0: 34, 2.0: 148, 3.0: 33}],
...,
[6, {0.0: 1164, 1.0: 99, 2.0: 125, 3.0: 56}],
[7, {0.0: 1111, 1.0: 152, 2.0: 105, 3.0: 76}],
[8, {0.0: 1056, 1.0: 207, 2.0: 81, 3.0: 100}]], dtype=object)
Where am I wrong?
I can set any values I want in axl[c].set_ylim([-10, 200]) it doesn't change anything on the output graph.
Update:
Ok, it seems not possible to set other value as 1 as starting y-axis value here.
