Question

我从服务器检索JSON数据并将其作为系列放入Highchart中。我遇到了这个错误：

错误：属性y =“NaN”的值无效highcharts.js：9

如果我从callChart函数发送chartSeries参数，则会发生错误。但是如果我复制chartSeries值并将其直接放在drawChart中，它就能显示图表。但是对于其他参数如chartCategory和chartTitle没有问题。

这是我的代码：

function callChart(){
 for (var i in jsonData){
        console.log('@i '+i);
        console.log('@subSegment i '+jsonData[i].subSegment);
        var chartTitle= jsonData[i].subSegment;
        console.log('categories '+ jsonData[i].categories);
        var chartCategory= jsonData[i].categories;
        console.log('series '+ JSON.stringify(jsonData[i].series));
        var chartSeries=JSON.stringify(jsonData[i].series);
        drawChart($('.chartContainer'),chartSeries,chartCategory,chartTitle);
        break;}}

这是drawChart的代码;

function drawChart(container,chartSeries,chartCategory,chartTitle) {
console.log('@ test');

console.log('@ chartSeries='+chartSeries);
console.log('@ chartCategory='+chartCategory);
console.log('@ chartTitle='+chartTitle);

//it works if I put the chartSeries directly here
/*chartSeries=[{"type":"column","stack":null,"pointPlacement":null,"name":"HDD","linkedTo":null,"id":"hdd","data":[30,30,70,90,37,200],"color":"greenColor","borderWidth":null},{"type":"column","stack":"old","pointPlacement":null,"name":"SSHD","linkedTo":null,"id":"sshd","data":[0,100,40,90,60,90],"color":"yellowColor","borderWidth":null},{"type":"column","stack":"old","pointPlacement":null,"name":"SSD","linkedTo":null,"id":"ssd","data":[50,100,40,90,60,100],"color":"blueColor","borderWidth":null},{"type":"column","stack":"forecast","pointPlacement":null,"name":"HDD","linkedTo":"hdd","id":null,"data":[30,80,40,100,60,90],"color":"greenColor","borderWidth":null},{"type":"column","stack":"forecast","pointPlacement":null,"name":"SSD","linkedTo":"ssd","id":null,"data":[30,80,40,100,60,90],"color":"yellowCollor","borderWidth":null},{"type":"spline","stack":null,"pointPlacement":null,"name":"Share","linkedTo":null,"id":null,"data":[30,80,40,100,60,90],"color":"black","borderWidth":null}] ;

if (!container.length) {
  return;
}

非常感谢。

好的，我已经找到了。

而是传递JSON.stringify（jsonData [i] .series），直接传递jsonData [i] .series。

由于

尝试使用外部参数生成图表时出错
