如何在 matplotlib 中填充闭合线图？

Question

我想将闭合线图\/绘图的内部变成填充的。 在此处输入图像描述<\/a>

    result = loadJson(jsonFile1)
    volume = result[2]
    flow = result[3]

    result2 = loadJson(jsonFile2)
    volume2 = result2[2]
    flow2 = result2[3]

    plt.axhline(y=0, color='k')

    plt.plot(volume, flow, alpha = 0.5, label = jsonFile1)
    plt.plot(volume2, flow2, alpha=0.5, label = jsonFile2)
    plt.xlabel("Volume")
    plt.ylabel("Flow")


    plt.title("Comparison between " + jsonFile1 + " and " + jsonFile2)
    plt.legend(loc='upper right')

    plt.show()```
