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
