# 准备数据
data = {
    'category': ['A', 'B', 'C', 'D', 'E'],
    'sub_category': ['Sub1', 'Sub2', 'Sub3', 'Sub4', 'Sub5'],
    'value': [10, 20, 30, 40, 50]
}

# 创建堆叠柱状图
source = ColumnDataSource(data=data)
p = figure(x_range=data['category'], plot_height=350, title="Stacked Bar Chart",
           toolbar_location=None, tools="")

p.vbar_stack(stackers=data['sub_category'], x='category', width=0.9, color=Spectral6, source=source,
             legend_label=data['sub_category'])

# 添加图片
image_url = "https://example.com/image.jpg"  # 图片的URL地址
image = ImageURL(url=[image_url], x=0, y=0, w=1, h=1)  # 创建ImageURL对象

# 绘制图像
p.image_url(url=[image_url], x=0, y=0, w=1, h=1, anchor="bottom_left", global_alpha=0.5)  # 绘制图像

# 显示图形
show(p)
