我想使用highcharts计算和绘制复数的大小。我的代码是在图中分别显示实数和虚数值。 ＆＃34; For循环＆＃34;我用过的是不行。请告诉我我哪里做错了？我是Highcharts的新手。

答案 0 :(得分：0)
rawDataFreq循环中似乎不存在 for
您应该尝试将原始数据存储在变量中，然后在series.dataname和for循环中引用它。
function makeChart(){
var rawDataFreq = [/* your data array */];
$('#container').highcharts({
/* code truncated */
series: [{
"name": "rawDataFreq",
"data": rawDataFreq
}]
/* code truncated */
});
for (var i = 0; i < rawDataFreq.length; i++) {
/* code truncated */
}
}
