Hi all,
Here's some code:
Mark
Here's some code:
import pandas as pd import matplotlib.pyplot as plt import time import numpy as np start_time = time.time() df = pd.DataFrame(columns=['DTE', 'Long Delta', 'Short Delta', 'Delta Spread']) # Checking all permutations covered by program: for dte in range(30,61): long_delta = np.arange(-0.1,-0.35,-0.05) short_delta = np.arange(-0.25,-0.50,-0.05) if dte == 30: for ld in long_delta: for sd in short_delta: plt.scatter(ld,sd) plt.tight_layout() #to prevent axis labels from being cut off in saved figure plt.xlabel('Long Delta') plt.ylabel('Short Delta') end_time = time.time() print('Elapsed time is {:.0f}ms'.format(1000*(end_time-start_time)))How do I reverse the axes on the graph so they go from largest to smallest (left to right and down to up)?
