[PYTHON] So zeichnen Sie mit matplotlib ein Balkendiagramm, das mehrere Serien zusammenfasst

# version
matplotlib == 3.2.2

import numpy as np
import matplotlib.pyplot as plt

#Vertikale Leiste
def barplot(ax, labels, datas):
    x = np.arange(len(labels))  # the label locations
    width = 0.35  # the width of the bars

    rects1 = ax.bar(x - width/2, datas[0]["val"], width, label=datas[0]["label"])
    rects2 = ax.bar(x + width/2, datas[1]["val"], width, label=datas[1]["label"])

    # Add some text for labels, title and custom x-axis tick labels, etc.
    ax.set_xticks(x)
    ax.set_xticklabels(labels)
