chart.getPosition(obj)不兼容

// 绘制柱状图文本
        let offset = -5
        let canvas2 = chart.get('canvas')
        console.log(canvas2.addGroup())
        let group = canvas2.addGroup()
        let shapes = {}
        data.map(function (obj) {
          let point = chart.getPosition(obj)
          console.log(point)
          let text = group.addShape('text', {
            attrs: {
              x: point.x,
              y: point.y + offset,
              text: 1213,
              textAlign: 'center',
              textBaseline: 'bottom',
              fill: '#808080'
            }
          })
          shapes[obj.year] = text // 缓存该 shape, 便于后续查找
        })
