Question

我正在学习JavaScript，并且拥有一些编程知识，并且最终可以解决问题，但我仍然遇到有关highcharts的问题。

<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
        <title>Highcharts Example</title>

        <!-- 1. Add these JavaScript inclusions in the head of your page -->
        <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
        <script type="text/javascript" src="http://code.highcharts.com/highcharts.js"></script>

        <!-- 2. Add the JavaScript to initialize the chart on document ready -->
        <script type="text/javascript">
            $(document).ready(function() {
                var options = {
                    chart: {
                        renderTo: 'container',
                        type: 'line'
                    },
                    title: {
                        text: 'Betting Performance'
                    },
                    xAxis: {
                        categories: []
                    },
                    yAxis: {
                        title: {
                            text: 'Yield (%)'
                        }
                    },
                    series: []
                };

                /*

                $.get('data.csv', function(data) {
                    // Split the lines
                    var lines = data.split('\n');
                    $.each(lines, function(lineNo, line) {
                        var items = line.split(',');

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

                        // the rest of the lines contain data with their name in the first position
                        else {
                            var series = {
                                data: []
                            };
                            $.each(items, function(itemNo, item) {
                                if (itemNo == 0) {
                                    series.name = item;
                                } else {
                                    series.data.push(parseFloat(item));
                                }
                            });

                            options.series.push(series);

                        }

                    });
                    var chart = new Highcharts.Chart(options);
                });
            });
        </script>
    </head>
    <body>
        <!-- 3. Add the container -->
        <div id="container" style="width: 1200px; height: 800px; margin: 0 auto"></div>
    </body>
</html>

现在，我已经成功完成了这项工作并附上了截图。

enter image description here 但正如你在底部看到的那样，有一个名为'Series 3'的系列

接下来是我的CSV文件作为纯文本

，1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23， 24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42 万里，-100，-100，-100，-58.75，-31，-9.17,9.63,18.3,29.08,38.5,41.19,43.56,46.79,39.45,32.81,26.77,28.64,18.71,24.52,28.53,29.04， 24.87,20.96,17.28,20.02,18.27,20.52,17.16,19.26,16.2,13.29,10.52,13.25,14.04,11.44,12.97,21.4,18.81,16.33,13.95,11.67,9.48 英里2，-100，-100，-100，-58.75，-22，-9.17,9.63,18.3,29.08,38.5,41.19,43.56,46.79,39.45,32.81,26.77,48.64,18.71,24.52,28.53,29.04 ，24.87,20.96,17.28,20.02,18.27,20.52,17.16,19.26,16.2,13.29,10.52,13.25,14.04,11.44,12.97,21.4,18.81,16.33,13.95,11.67,9.48

如图所示，这可以很好地绘制到图表中。我制作了两组数据，以突出显示多个系列的工作，并且有一个系列不是问题。所有数据点均从1-42号绘制，具有适当的y值。

我不知道额外系列的来源和原因。我尽可能多地关注了高图演示，但现在我迷失了。

Answer 1

正如jack R Abbit在评论中所发表的那样，excel在CSV结尾添加了空格。上帝知道为什么。删除那个空格修复了问题，hunky dory！再次感谢那些帮助过的人，并希望其他人能够遇到这个并得到帮助。
