+每条推荐是一个用户会关心的业务问题，加上能直接执行的汇总请求
+- title：问题本身，如“各区域销售额对比”“月度订单趋势”，20 字以内，同时用作图表标题
+- 3 条要覆盖不同角度（不同的分类列或不同的指标），不能只是换图表类型
+- table：必须是输入里的表名（t1、t2……）；列名必须和输入完全一致，不要改写、翻译或编造

+ - 不要选 id 类的列，也不要选去重值很多的文本列（几十个以上）做分类
+- request.metrics：1 到 3 个指标，量纲要相近，放在同一张图里才有意义；pie、funnel 只写 1 个
+ - sum、avg 只能用于数值列；count 可以不写 column，统计行数；count_distinct 统计不重复个数
+ - 不要对 id、编码、年份这类数值列求和或平均

+- request.order_by：by 必须是结果里的列名（分组列名或指标的列名）；时间趋势按分组列升序，排名按指标降序
+- request.limit：趋势可写 100，排名、占比写 20 以内

+## 列的含义
+columns 里列出输入的每一列，table 和 name 与输入完全一致
+- label：中文含义，3 到 10 个字；列名已经清楚时与列名相同，列名是缩写或拼音时写出完整含义，不确定时不要猜，沿用列名
+- role：dimension（可用来分组的分类，如地区、产品）、measure（可汇总的数值，如金额、数量）、time（日期时间）、id（编号、编码，不适合汇总）、other
+- unit：单位，如“元”“件”“%”；没有或不确定时留空

+---
+
+# 用上传的数据做图
+
+## 步骤
+
+1. 同一轮一起调用 describe_data（看要用的表有哪些列、类型和常见取值）和 get_component_materials（看图表的默认配置）；替换已有图表时再一起调用
+ get_nodes
+2. 结果的形状没把握时（类目有多少个、日期粒度对不对），先用 query_data 试查；分组、排序、筛选、取前几名都在 SQL
+ 里完成，行数控制在图表看得清的范围，类目一般不超过 20 个，趋势按月或按周聚合
+3. 图表数据写成 {"$query": "SELECT ..."}，后端把查询结果写进组件；不要自己逐行抄数据
+4. 用 apply_actions 提交，按返回的列名和行数核对
+
+## 写法
+
+- 数据写在 props.option.dataset.source：新增时写在 node 里；替换已有图表时用
+ update，section=props，path=["option", "dataset", "source"]
+- 查询结果的列名就是 dataset.source 每一项的键。SQL 里用 AS 起好别名，series 的 encode
+ 引用这些别名，键沿用物料默认配置的写法（x/y、itemName/value 等）；换了数据就在同一批里一起改 encode，否则图表没有数据，提交会报错
+- 替换已有图表时 series 不能整个替换，encode 用 update 逐个改，例如 path=["option", "series", 0, "encode", "x"]
+ ；系列名改 ["option", "series", 0, "name"]。也可以让 SQL 的别名沿用原 encode 的列名，就不用改 encode
+- 新增组件时 series 数组整体替换：以物料默认配置的每一项为基础写完整（type、stack 等保留），只改 encode 和 name
+- 多个系列（例如每月线上、线下各一根柱子）用宽表，每个系列一列：长表（每行一个类别和数值）用 PIVOT（要写 IN 列出取值）或 SUM
+ (CASE WHEN ...) 转成宽表；反过来宽表转长表用 UNPIVOT
+- 日期按需要的粒度转成文字，例如 strftime (月份, '%Y-%m')，坐标轴上不出现完整的时间
+- 指标卡、单个数值不用 $query：先用 query_data 查出来，再直接写数字
+- 用了 $query 的新增组件不用写 sample_data，后端会设为 false；标题按数据的内容写
+
+## 数据不合适时
+
+- 找不到用户说的数据（表或列不存在、指的是哪一列不明确）时，追问用哪张表、哪一列；用户只想先看效果时，用示例数据并在回复里说明
+- 百分比的值是小数（0.85 表示 85%），要显示成百分比时在 SQL 里乘 100，或在标签格式里处理
+- 解析警告说排除了合计行时，表里已经没有合计；需要总数时用 SUM 自己算
