我试图使用雅虎财务数据来生成像这样http://www.highcharts.com/stock/demo/candlestick-and-volume的Highcharts烛台图表。但我不断收到此错误:http://www.highcharts.com/errors/15 Highcharts错误#15
Highcharts期望对数据进行排序
当您尝试创建数据未按升序X顺序排序的折线图或股票图表时,会发生这种情况。出于性能原因,Highcharts不对数据进行排序,而是要求实施者预先对数据进行排序。
我的代码如下。
$(function () {
$.getJSON('http://websitescraper.heroku.com/?url=http://ichart.finance.yahoo.com/table.csv?s=000338.sz&callback=?', function (csvdata) {
//console.log(csvdata);
var arr = csvdata.split('\n').slice(1);
var data = [];
for (var i = arr.length-1; i >= 0; --i) {
//console.log(arr[i]);
var line = arr[i].split(',');
line[0] = Date.parse(line[0]);
line = $.map(line, function(v) {
return parseFloat(v);
});
line = line.slice(0,6);
//var j = JSON.stringify(line.slice(0,0+6));
console.log(line);
data.push(line);
}
data = JSON.stringify(data.slice(1));
console.log(data);
run(data);
});
});
function run(data) {
// split the data set into ohlc and volume
var ohlc = [],
volume = [],
dataLength = data.length,
// set the allowed units for data grouping
/*groupingUnits = [[
'week', // unit name
[1] // allowed multiples
], [
'month',
[1, 2, 3, 4, 6]
]],*/
i = 0;
for (i; i < dataLength; i += 1) {
ohlc.push([
data[i][0], // the date
data[i][1], // open
data[i][2], // high
data[i][3], // low
data[i][4] // close
]);
volume.push([
data[i][0], // the date
data[i][5] // the volume
]);
}
// create the chart
$('#container2').highcharts('StockChart', {
rangeSelector: {
selected: 1
},
title: {
text: 'Shanghai Composite Index Historical'
},
yAxis: [{
labels: {
align: 'right',
x: -3
},
title: {

},
height: '60%',
lineWidth: 2
}, {

},
title: {

},
top: '65%',
height: '35%',
offset: 0,

}],
series: [{
type: 'candlestick',
upLineColor: 'red',
downLineColor: 'green',
name: 'SSE',
data: ohlc,
/*dataGrouping: {
units: groupingUnits
}*/
}, {
type: 'column',
name: 'Volume',
data: volume,
yAxis: 1
/*dataGrouping: {
units: groupingUnits
}*/
}]
});
}
有人可以帮忙吗?非常感谢!
答案 0 :(得分:2)
问题在于 data = JSON.stringify(data.slice(1));
。它将数组转换为字符串,因此 Highstock
无法识别它。删除JSON.stringify
,它会正常工作:
data = data.slice(1);
这是DEMO。
