运行 wyn-visual-tools init, 输入工程名称, cli工具将会自动安装依赖。将得到以下的工程:
运行 npm install echarts 以及 npm install @types/echarts --save-dev
运行 wyn-visual-tools develop 启动调试工具服务端
在 src/visual.ts 导入echarts 并在构造器中创建echarts 实例。
添加一个render方法并在update方法中调用。目前我们先画一个mock chart。
在仪表板设计器中添加开发工具组件, 点击开发工具的刷新按钮。现在可以看到效果。
在capabilities.json中添加数据绑定信息。
在update方法中将数据视图转化为echars需要的数据结构。
在onResize方法中添加对应处理。
添加自定义属性。
在render方法中使用自定义属性。
添加标题和交互支持。
添加一些action。例如聚焦, 过滤和排名。
最后记得及时销毁实例。
设置可视化插件的名字。
运行 wyn-visual-tools package
上传simple_echarts.viz。 就可在仪表板设计器中使用该可视化插件了。
以下为相关代码:
