概述
本 Demo 展示了帕累托函数迷你图的使用方法，以员工迟到原因为例，演示了水平和垂直两种布局方式。用户可以通过右侧面板实时调整标签类型、高亮项、目标线位置和颜色等参数，直观地看到帕累托分析结果。
实现思路
创建两个工作表，分别展示水平和垂直布局的帕累托迷你图
准备迟到原因统计数据，包括原因、案例数、颜色和柱子大小
使用 PARETOSPARKLINE 公式为每个数据点创建对应的迷你图单元格
监听面板控件的 change 事件，动态更新公式参数
通过公式引用实现实时交互效果
代码解析
创建水平帕累托迷你图
这段代码为每一行数据设置帕累托迷你图公式。关键点：
points 参数使用 $B$3:$B$8 绝对引用，所有单元格共享同一组数据
pointIndex 使用 ROW()-2 动态计算当前数据点的索引（从第 2 行开始）
vertical 参数设为 false，表示水平显示
其他参数从 HTML 控件动态获取
响应参数变化
当用户修改标签类型、高亮项或目标线参数时，触发 applyChanges 函数重新设置公式。
运行效果
打开 Demo 后，默认显示水平布局的工作表，展示员工迟到原因的帕累托分析
切换到 "Vertical" 工作表，可以看到垂直布局的帕累托图
在右侧面板中调整参数，迷你图会实时更新：
标签类型：可选择无、累计百分比或单一百分比
高亮项：选择要高亮显示的数据项（红色标记）
目标1和目标2：设置两条参考线的位置（0-1 之间）
目标线颜色：自定义两条目标线的显示颜色
通过分析可以快速识别：交通、育儿和公共交通是造成 80% 员工迟到的主要原因
API 参考
PARETOSPARKLINE 函数
points：数据区域，如 "B2:B7"
pointIndex：数据点索引（从 1 开始），可以是数字或单元格引用
colorRange：颜色区域，指定每个柱子的颜色
target、target2：目标线位置（0-1 之间）
highlightPosition：高亮项索引，该数据点显示为红色
label：标签类型，0=不显示，1=累计百分比，2=单一百分比
vertical：是否垂直显示，true=垂直，false=水平
targetColor、target2Color：目标线颜色
labelColor：标签前景色
barSize：柱子大小（相对于单元格宽度/高度的百分比，0-1）
