######### setting fig size
# Get current size
fig_size = plt.rcParams["figure.figsize"]
 
# Prints: [8.0, 5.0]
print "Current size:", fig_size

# Set new figure width to 8 and height to 5
fig_size[0] = 8
fig_size[1] = 5
plt.rcParams["figure.figsize"] = fig_size


######### adding only x-axis and y-axis
import matplotlib.pyplot as plt
fig, ax = plt.subplots()
ax.spines['bottom'].set_color('#a1a1a1')
ax.spines['left'].set_color('#a1a1a1')


######### saving img without axises and boarders
fig = plt.imshow(NumpyArray) 

plt.axis('off')

figure = plt.gcf() # get current figure
figure.set_size_inches(13.65,3.44) # inches!!!! 

fig.axes.get_xaxis().set_visible(False)
fig.axes.get_yaxis().set_visible(False)

plt.savefig('result.png', bbox_inches='tight', pad_inches = 0, dpi = 100 )
