# 设置字体样式和大小

# 绘制柱状堆叠图，设置柱子颜色和标签

###设置柱子宽度
width = 0.45

# bar_plot3 = bar_plot2+bar_plot
# 添加标题、标签和图例
# ax.set_title('Temperature / ℃', fontsize=24)
ax.set_xlabel('City', font)
ax.set_ylabel('Value', font)
ax.legend(ncol=2, loc='best', fontsize=20)
ax.set_ylim(0,53)
##x轴刻度名称、倾斜角度
new_x = ['City '+i for i in x]
plt.xticks(np.arange(len(x)), new_x, rotation=45)
# 设置坐标轴刻度字体和字号
font_tick = {'family': 'Times New Roman', 'size': 24}
for label in ax.get_xticklabels() + ax.get_yticklabels():
    label.set_fontproperties(font_tick)
# 调整字体颜色、柱子宽度等其他参数
for rect, height_1, height_2 in zip(bar_plot2, y1, y2):
    height_2 = rect.get_height()
    ax.text(rect.get_x() + rect.get_width()/2., height_1 + height_2 + 0.5, '%d' % int(height_2),
            ha='center', va='bottom', fontsize=20, color='green', fontname='Times New Roman')

            ha='center', va='bottom', fontsize=20, color='blue', fontname='Times New Roman')
##右上边框是否可见
# ax.spines['top'].set_visible(False)
# ax.spines['right'].set_visible(False)
##刻度线长宽设置
ax.tick_params(axis='x', direction='out', length=6, width=2)
ax.tick_params(axis='y', direction='in', length=6, width=2)
plt.tight_layout()
plt.savefig("C:/Users/ypzhao/Desktop/a.jpg",dpi=600)
