我正在尝试在线条或面积图的工具提示中显示开，高，低，收盘。现在，行和面积图的数据正在一个看起来像这样的JSON数组中发送
{timestamp, close}
现在，对于OHLC或烛台图表，此JSON更改为
{timestamp,open, high, low, close}
我尝试过这种只适用于OHLC和烛台的方法。
tooltip: {
valueDecimals: 2,
useHTML: true,
formatter: function() {
/*
* tooltip formatter function
*
*/
var d = new Date(this.x);
var s = '';
if (chartGlobalOptions.range.indexOf("m") >= 0) {
s += '<b>' + Highcharts.dateFormat('%b %e, %Y', this.x) + '</b><br />';
} else {
s += '<b>' + Highcharts.dateFormat('%b %e, %Y [%H:%M]', this.x) + '</b><br />';
}
$.each(this.points, function(i, point) {
if (point.series.name.indexOf("Volume") >= 0) {
/*
* if the series is volume, then don't show the decimals
*
*/
s += '<b><span style = "color:' + point.series.color + ';">' + point.series.name + ' </span>' + ' : ' + Highcharts.numberFormat(point.y, 0) + '</b><br />';
} else if (point.series.type == 'candlestick' || point.series.type == 'ohlc') {
s += '<b><span style = "color:' + point.series.color + ';">' + point.series.name + ' : ' + Highcharts.numberFormat(point.point.close, 3) + '</b><br />';
s += '<span style ="color:' + point.series.color + ';">Open</span>: ' + point.point.open +
'<br/><span style ="color:' + point.series.color + ';">High</span>: ' + point.point.high +
'<br/><span style ="color:' + point.series.color + ';">Low</span>: ' + point.point.low +
'<br/><span style ="color:' + point.series.color + ';">Close</span>: ' + point.point.close + '<br/>';
}
else {
s += '<b><span style = "color:' + point.series.color + ';">' + point.series.name + ' </span>' + ' : ' + Highcharts.numberFormat(point.y, 3) + '</b><br />';
}
});
return s;
},
shared: true
},
为了在折线图的工具提示中显示ohlc值，需要进行哪些修改？我一直试图找到一个解决方案很长一段时间没有任何成功。
谢谢，
Maxx的
修改
这是我正在设置的系列选项
series: [{
type: chartGlobalOptions.chartTypes.name,
name: $('#symbol-name').text(),
data: data.prices,
id: 'Price Axes',
dataGrouping: {
units: groupingUnits
}
}, {
type: 'column',
name: 'Volume',
data: data.volume,
yAxis: 1,
dataGrouping: {
units: groupingUnits,
approximation: 'close'
}
}]
以下是我从服务器获取的数据。
{"prices":[{"x":1387377184000,"y":1.05,"high":1.06,"low":1.05,"open":1.06,"close":1.05},{"x":1387377509000,"y":1.04,"high":1.06,"low":1.04,"open":1.05,"close":1.04},{"x":1387378295000,"y":1.04,"high":1.04,"low":1.04,"open":1.04,"close":1.04},{"x":1387379370000,"y":1.04,"high":1.04,"low":1.04,"open":1.04,"close":1.04},{"x":1387380217000,"y":1.04,"high":1.04,"low":1.04,"open":1.04,"close":1.04},{"x":1387381181000,"y":1.04,"high":1.04,"low":1.04,"open":1.04,"close":1.04},{"x":1387381324000,"y":1.03,"high":1.03,"low":1.03,"open":1.03,"close":1.03},{"x":1387382146000,"y":1.03,"high":1.03,"low":1.03,"open":1.03,"close":1.03},{"x":1387383229000,"y":1.03,"high":1.03,"low":1.03,"open":1.03,"close":1.03}],

以下是我在服务器中设置数据的方法
$this->price[] = array (
$eachRow[ "timestamp" ] * 1000 ,
$eachRow[ "close" ] * 1 ,
$eachRow[ "high" ] * 1 ,
$eachRow[ "low" ] * 1 ,
$eachRow[ "open" ] * 1 ,
$eachRow[ "close" ] * 1
) ;
return json_encode ( array (
"prices" => $this->resultArray[ "prices" ] ,
"volume" => $this->resultArray[ "volume" ] ));
我从服务器获取值后刚开始var data = JSON.parse(data);。请让我知道我的程序有什么问题。我的意思是如果我直接在数据对象中硬编码相同的值，我得到正确的结果。
答案 0 :(得分：2)
您需要将该信息添加到您的积分中，例如：
series: [{
//type : 'ohlc',
name: 'AAPL Stock Price',
data: [{
x: 1367884800000,
y: 100,
high: 150,
low: 90,
close: 120,
open: 100
}, {
x: 1367984800000,
y: 120,
high: 170,
low: 120,
close: 160,
open: 120
}, {
x: 1368084800000,
y: 160,
high: 160,
low: 90,
close: 120,
open: 160
}]
}]

注意：当你有很多分数并且将使用dataGrouping时，点信息（opten / high / low / close）将会丢失。所以这只适用于已禁用的dataGrouping。
