hz4th_coder 0e15d43ed4 feat: X轴名右侧不再截字+轴名位置可选(右侧/下方居中)+刻度方向下拉10°档+自定义手动输入 v1.17.1 2026-08-23 10:09:14 +08:00
hz4th_coder 59788639cb chore: 版本号更新至 v1.17.0 2026-08-23 09:51:59 +08:00

hz4th_coder 86669f9cf5 feat: X轴轴名+刻度倾斜角度可调(默认水平) + 双Y轴图例按左右轴分组放到对应轴边上 v1.17.0 2026-08-23 09:51:18 +08:00
hz4th_coder 2cc6491440 feat: 数据方向(行=系列)+每系列类型/双轴 + 多图大标题/共享图例 v1.16.0
- 图表模式新增'数据方向':列=系列(默认)/行=系列(第一行是横坐标,每行一个系列),每行可独立设柱状/折线 + 左右轴量度
- 后端 buildChartOption/GET /api/chart 支持 rowsAsSeries + seriesAxis(按系列下标指定左右轴)
- 多图合并每张小图新增:行=系列、双Y轴(左右量度不同)、每系列独立图表类型与坐标轴配置
- 多图合并新增图片大标题(bigTitle),居中显示在顶部
- 多图合并新增图例方式(legendMode):own 各自图例(默认)/shared-top 共用图例顶部/shared-bottom 共用图例底部,共用时各子图隐藏自己的图例、系列合并去重、超宽自动换行
- /api/combine 后端同步支持 bigTitle/legendMode(含深色主题文字适配)
- 收藏功能完整支持新字段(combine 大标题/图例方式/每系列配置,chart 数据方向),编辑恢复正常
- 文档/API.md/README 更新,版本 1.16.0

hz4th_coder 7a03ecc063 feat: 新增饼图/雷达图图表类型
- 单图模式图表类型新增:饼图(环形占比,第一列=名称/第一系列=数值)、雷达图(多维度对比,第一列=维度/每系列=多边形)
- 多图合并的每张图也可选饼图/雷达图
- 后端 /api/chart 与 /api/combine 的 chartType 支持 pie/radar
- 饼图/雷达图自动隐藏坐标轴/网格/双轴等不适用配置
