Answer 1

您的代码中有一些错误。首先，您似乎打算从第一行获取类别，但随后从所有其他行获取类别。然后，您只需使用每行的第一项（始终是日期）来创建您的类别。显然这不是你想要的。

这个 fiddle: http://jsfiddle.net/hibiscus/ec8gm8oq/ 做了我相信你正在尝试做的事情。 CSV 数据只是作为变量添加以简化操作。相关代码是这样的：

var categoryIndex = 0;
var categories = [];

$.each(lines, function(lineNo, line) 
            {                    
                var items = line.split(',');
                // header line containes categories

                if (lineNo == 0) {                        
                    for (var i=1; i < items.length; i++) {
                        categories.push(items[i]);
                    }
                }

                if (lineNo > 0) {   
                    $.each(items, function(itemNo, item) 
                    {                            
                        if (itemNo == 0) options.xAxis.categories.push(item);
                    });

                    var series = 
                    { 
                        data: []
                    };

                    $.each(items, function(itemNo, item) 
                    {                            
                        if (itemNo == 0) 
                        {
                            series.name = categories[categoryIndex++];
                        } 
                        else 
                        {                                                                                            
                            series.data.push(parseFloat(item));
                        }
                    });
                    options.series.push(series);
                }

            });
