Question

我正在vue应用程序中使用highchart库在图形中显示数据。下面是我所面临的问题的代码片段。问题在于数据系列中，当数据数组的第一个元素包含0值时，它在映射中显示为0，但是如果0在任何其他位置，则对于特定名称它不显示为0。 / p>

series: [{
  name: 'John',
  data: [5, 0, 4, 0, 2]
 }, {
  name: 'Jane',
  data: [0, 0, 3, 0, 1]
 }, {
  name: 'Joe',
  data: [0, 4, 4, 2, 5]
 }]

在上述系列数组中，John，Jane和Joe的第一个值分别为5、0、0，第二个值分别为0、0、4。但是在下面的图形中，第一列图形显示为0，第二列图形显示为0。请帮助解决此问题。我也不想在第一栏中显示那个0。

plotOptions: {
              column: {
                  stacking: 'normal',
                  dataLabels: {
                    enabled: true,
                    formatter: function(){
                        var val = this.y;
                        if (val === 0) {
                            return '';
                        }
                        return val;
                    },
                  }
              }
          },

这是解决问题的方法
