[Matplotlib-users] Error in Boxplot

Dear List, boxplots are not plotted correctly in case the 'x' argument has an even number of elements. So when I do: import matplotlib.pyplot as plt import numpy as np r_odd = np.array([1,2,3,4,5]) plt.boxplot(x=r_odd) plt.show() I get the correct boxplot but when I do: r_even = np.array([1,2
