Hi Yogesh,
Doesn't the following example fulfill your needs (already posted to "How to
save file in to image in desired resolution in matplotlib?")?
fig = plt.figure(figsize=(9.4, 7.8))
ax = plt.axes([0.0, 0.0, 1.0, 1.0]) # leaves no white space around the axes
ax.plot([1, 2, 4], lw=5)
ax.set_xticks([]) # removes ticks
ax.set_yticks([])
fig.savefig('test.png', dpi=100)
Kind regards,
Matthias
