Box plot with min, max, average and standard deviation
The answer given by @Roland above is important: a box plot shows fundamentally different quantities, and if you make a similar plot using the quantities you have, it might confuse users. I might represent this information using stacked errorbar plots. For example:
import matplotlib.pyplot as pltimport numpy as np# construct some data like what you have:x = np.random.randn(100, 8)mins = x.min(0)maxes = x.max(0)means = x.mean(0)std = x.std(0)# create stacked errorbars:plt.errorbar(np.arange(8), means, std, fmt='ok', lw=3)plt.errorbar(np.arange(8), means, [means - mins, maxes - means], fmt='.k', ecolor='gray', lw=1)plt.xlim(-1, 8)
