# 柱状图
## Content 约束
- 数据点 ≤ 12
- 同一数据系列用同一颜色(不要每个柱不同色)
- Y 轴必须有单位标注(如 "万元"、"人次"
## Layout 选型
- **脚本生成坐标**(推荐):用 .cjs 脚本计算柱体位置和高度,脚本输出 JSON 文件后调用 `npx -y @larksuite/whiteboard-cli@^0.2.13` 渲染
- **绝对定位手写**:简单柱状图(≤ 5 个柱)可手写坐标
## Layout 规则
- 白板坐标系 Y 轴向下为正,图表"底部原点"拥有最大 Y 值,柱体向上生长时 Y 减小
- 柱体等宽等间距,底部对齐 X 轴
- 柱体高度:`height = (value / maxValue) * chartHeight`
- 柱体 Y 坐标:`y = originY - height`
- 坐标轴用 connector 直线末端带箭头endArrow: "arrow"
- 格线用虚线 connectorlineStyle: "dashed"endArrow: "none"
- 刻度线短横线 connectorendArrow: "none"
- 数值标注放在柱体顶部上方
- 类别标签放在 X 轴下方,居中对齐柱体
## 坐标与尺寸计算指南
白板坐标系中,**X 轴向右为正Y 轴向下为正**。因此图表的"底部原点"实际上拥有最大的 Y 坐标,图形向上生长时 Y 坐标在不断减小。
1. **确定图表区域**
- 设定图表区高度 `chartHeight` 和宽度 `chartWidth`
- 设定左下角坐标原点 `(originX, originY)`
- 示例originX=80, originY=480, chartWidth=1000, chartHeight=400
2. **Y 轴映射(计算高度)**
- 找出数据的最大值 `maxValue`
- 将 maxValue 向上取整到"整数刻度"(如数据最大 190 → maxValue 取 200
- 柱子高度:`height = (value / maxValue) * chartHeight`
- 柱子 Y 坐标:`y = originY - height`
3. **X 轴映射(计算宽度与 X 坐标)**
- 将 chartWidth 按数据个数均分:`slotWidth = chartWidth / barCount`
- 设定柱子间距 `barGap`(推荐 slotWidth 的 25%-30%
- 柱子宽度:`barWidth = slotWidth - barGap`
- 第 i 根柱子 X 坐标:`x = originX + i * slotWidth + barGap / 2`
4. **Y 轴刻度计算**
- 将 0 到 maxValue 等分为 4-6 个刻度
- 每个刻度的 Y 坐标:`gridY = originY - (tickValue / maxValue) * chartHeight`
- 刻度线:从 (originX-10, gridY) 到 (originX, gridY) 的短横线
- 网格线:从 (originX, gridY) 到 (originX+chartWidth, gridY) 的虚线
## 完整 JSON 示例
以下示例3 根柱子,数据 [120, 200, 150]maxValue=200originX=80, originY=480, chartWidth=900, chartHeight=400。
- slotWidth = 900 / 3 = 300
- barGap = 80, barWidth = 220
- 刻度0, 50, 100, 150, 200每 50 一格gridInterval = 80px

坐标推导验证:
- bar-0 (120): height = (120/200)*400 = 240, y = 480-240 = 240
- bar-1 (200): height = (200/200)*400 = 400, y = 480-400 = 80
- bar-2 (150): height = (150/200)*400 = 300, y = 480-300 = 180
- bar-0 x = 80 + 0*300 + 80/2 = 120, bar-1 x = 80 + 1*300 + 40 = 420, bar-2 x = 80 + 2*300 + 40 = 720
## 陷阱
- 单系列用多色(不专业):同一数据系列所有柱体应使用同一颜色
- 缺 Y 轴单位标注,读者无法理解数值含义
- 柱体间距不均匀(脚本需统一计算 barGap
- Y 轴刻度线和格线误带箭头
- 坐标轴忘记带箭头
此场景必须用 .cjs 脚本生成。Agent 使用时只需修改 `data` 数组,其余坐标与柱体高度全自动计算。
```javascript
const { writeFileSync } = require('fs');
