如何通过Spec的方式声明多个View？ #6123

问题描述

我想通过Spec声明的方式实现如下的效果(同时有线+点)： 在官网的DEMO中是可以运行的：

但是在sandbox中运行失败： 或者采用以下代码也运行失败;

    const data = [
        { month: 'Jan', city: 'Tokyo', temperature: 7 },
        { month: 'Jan', city: 'London', temperature: 3.9 },
        { month: 'Feb', city: 'Tokyo', temperature: 6.9 },
        { month: 'Feb', city: 'London', temperature: 4.2 },
        { month: 'Mar', city: 'Tokyo', temperature: 9.5 },
        { month: 'Mar', city: 'London', temperature: 5.7 },
        { month: 'Apr', city: 'Tokyo', temperature: 14.5 },
        { month: 'Apr', city: 'London', temperature: 8.5 },
        { month: 'May', city: 'Tokyo', temperature: 18.4 },
        { month: 'May', city: 'London', temperature: 11.9 },
        { month: 'Jun', city: 'Tokyo', temperature: 21.5 },
        { month: 'Jun', city: 'London', temperature: 15.2 },
        { month: 'Jul', city: 'Tokyo', temperature: 25.2 },
        { month: 'Jul', city: 'London', temperature: 17 },
        { month: 'Aug', city: 'Tokyo', temperature: 26.5 },
        { month: 'Aug', city: 'London', temperature: 16.6 },
        { month: 'Sep', city: 'Tokyo', temperature: 23.3 },
        { month: 'Sep', city: 'London', temperature: 14.2 },
        { month: 'Oct', city: 'Tokyo', temperature: 18.3 },
        { month: 'Oct', city: 'London', temperature: 10.3 },
        { month: 'Nov', city: 'Tokyo', temperature: 13.9 },
        { month: 'Nov', city: 'London', temperature: 6.6 },
        { month: 'Dec', city: 'Tokyo', temperature: 9.6 },
        { month: 'Dec', city: 'London', temperature: 4.8 },
      ];

      const chart = new G2.Chart({
        container: 'testChart12',
        autoFit: true,
      });

      chart.options({

        data:data,
        encode: {
          x: 'month',
          y: 'temperature',
          color: 'city',

        },
        children: [{
          type: 'view',
          children: [
            { type: 'line', encode:{shape: 'smooth'} },
            {
              type: 'point',

              style: {
                fill: 'white'
              }
            }],
        }]
      });

      chart.render();
