我正在尝试从CSV文件创建一个图表,其中包含每个时间值的多个数据值。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。
以下是我的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 和储蓄以及沿x轴绘制时间。任何帮助,将不胜感激。我使用标准代码导入Highcharts的CSV文件,但我确定我需要以某种方式更改它。谢谢!
var options = {
chart: {
renderTo: 'container',
defaultSeriesType: 'column'
},
title: {
text: 'Wind Turbine Hourly Production'
},
xAxis: {
categories: []
},
yAxis: {
title: {
text: 'kWh'
}
},
series: []
};
/*
Load the data from the CSV file. This is the contents of the file:

John,8,4,6,5

Joe,86,76,79,77
Janet,3,16,13,15
*/
$.get('medford-hour.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);
}
});
答案 0 :(得分:1)
您需要编写自己的解析器。这是一个简单的例子,它看起来如何:
var lines = data.split('\n');
$.each(lines, function (lineNo, line) {
var items = line.split(',');
if(lineNo !== 0) {
var x = + new Date(items[1]+'/'+items[2]+'/'+items[0]+' '+items[4]),
kwh = parseFloat(items[5]),
savings = parseFloat(items[6]);
if(!isNaN(kwh) && !isNaN(savings)){
options.series[0].data.push([x,kwh]);
options.series[1].data.push([x,savings])
}
}
}
