# 設置刻度
plt.xticks(x_15, a, fontproperties=my_font, fontsize=12)

# 添加描述信息

plt.ylabel("票房", fontproperties=my_font, fontsize=14)
plt.title("9月14日-9月16日電影票房", fontproperties=my_font, fontsize=22)

# 添加網格
plt.grid(alpha=0.4)

# 繪製
plt.bar(x_14, b_14, width=width, label="9月14日")
plt.bar(x_15, b_15, width=width, label="9月15日")

# 添加圖例
plt.legend(prop=my_font)

# 保存圖形
plt.savefig("./繪製多條條形圖.png")
