我正在尝试从包含每个时间值的多个数据值的 CSV 文件创建图表。我想绘制其中两个数据点,但无法弄清楚如何将 CSV 文件导入数组。
这是我的 CSV 示例
Year,Month,Day,Hour,Time,kWh,Savings,Total kWh
2013,02,06,11,11:00,0,0,308135
2013,02,06,11,11:59,15,1.875,308150
2013,02,06,12,12:59,27,3.375,308177
2013,02,06,13,13:59,34,4.25,308211
2013,02,06,14,14:59,32,4,308243
我想在 y 轴上绘制kWh和Savings,在 x 轴上绘制 Time。任何帮助,将不胜感激。我正在使用标准代码为 Highcharts 导入 CSV 文件,但我确信我需要以某种方式对其进行更改。谢谢!
var options = {
chart: {
renderTo: 'container',
defaultSeriesType: 'column'
},
title: {
text: 'Wind Turbine Hourly Production'
},
xAxis: {
categories: []
},
yAxis: {
title: {
text: 'kWh'
}
},
series: []
};

}

options.series.push(series);
}
