我是Highcharts的新手并尝试通过阅读CSV文件来绘制图表。当我提取并尝试显示时，我看到Y轴的值是一行（垂直）而不是水平线上的点。 请告诉我如何将其转换为辅助X轴。
我的整个代码：

请帮助，非常感谢!!!
提前多多感谢。

我创建了三个轴，每个轴用于数据中的一列，其中第一列是category - time。首先创建系列，否则你将为每一行创建系列（你已经这样做了）。创建系列之后，将项目从一行推送到特定系列，并在创建图表之前完成步骤 - 将系列推送到选项。
var data = 'Time,users,AverageSec,Volume\n8:00,2325,0.627,28821\n7:55,1529,0.609,19124\n7:50,1095,0.544,15825';
// Split the lines
var lines = data.split('\n');
var series = {
data: []
};
var series1 = {
yAxis: 1,
data: [],
type: 'spline'
};
var series2 = {
yAxis: 2,
data: []
};
$.each(lines, function (lineNo, line) {
var items = line.split(',');
// header line contains names
if (lineNo == 0) {
series1.name = items[1];
series.name = items[2];
series2.name = items[3];
/*$.each(items, function (itemNo, item) {
if (itemNo > 0)
series.name = item;
});*/
}
// the rest of the lines contain data with their name in the first position
else {
$.each(items, function (itemNo, item) {
// first item on line - category/time
if (itemNo == 0) {
options.xAxis.categories.push(item);
} else if (itemNo == 1) {
series1.data.push(parseFloat(item));
} else if(itemNo == 2){
series.data.push(parseFloat(item));
} else if(itemNo == 3){
series2.data.push(parseFloat(item));
}
});
}
});
options.series.push(series);
options.series.push(series1);
options.series.push(series2);
var chart = new Highcharts.Chart(options);
