Here's my code, and I'd like to set a size for the output image:
fig, ax1 = plt.subplots()
color = 'tab:red'
ax1.plot(range(len(d)), d, color=color)
ax1.tick_params(axis='y', labelcolor=color)
ax2 = ax1.twinx()
color = 'tab:blue'
ax2.plot(range(len(pips)), pips, color=color)
ax2.tick_params(axis='y', labelcolor=color)
plt.show()
