这是我的json数据
var data = [
{"unit":"a", "status":"Stopped / Idle", "val":21.2022222222222222},
{"unit":"a", "status":"Working", "val":53.3066666666666667},
{"unit":"a", "status":"Headland Turning", "val":0.04694444444444444444},
{"unit":"a", "status":"Transport", "val":5.1425000000000000},
{"unit":"b", "status":"Stopped / Idle", "val":334.7358333333333333},
{"unit":"b", "status":"Working", "val":212.6386111111111111},
{"unit":"b", "status":"Headland Turning", "val":26.2955555555555556},
{"unit":"b", "status":"Transport", "val":0.00444444444444444444}
];
unit
是类别
我希望数据可以按以下方式格式化,以便我可以插入HighCharts中的series
选项:
series: [{
name: 'Stopped / Idle',
data: [21.2022222222222222, 334.7358333333333333]},
{
name: 'Working',
data: [53.3066666666666667, 212.6386111111111111]},
{
name: 'Headland Turning',
data: [0.04694444444444444444, 26.2955555555555556]},
{
name: 'Transport',
data: [5.1425000000000000, 0.00444444444444444444]}]
});
谢谢。

var data = [
{"unit":"a", "status":"Stopped / Idle", "val":21.2022222222222222},
{"unit":"a", "status":"Working", "val":53.3066666666666667},
{"unit":"a", "status":"Headland Turning", "val":0.04694444444444444444},
{"unit":"a", "status":"Transport", "val":5.1425000000000000},
{"unit":"b", "status":"Stopped / Idle", "val":334.7358333333333333},
{"unit":"b", "status":"Working", "val":212.6386111111111111},
{"unit":"b", "status":"Headland Turning", "val":26.2955555555555556},
{"unit":"b", "status":"Transport", "val":0.00444444444444444444}
];
var seriesData = [];
var xCategories = [];
var i, cat;
for(i = 0; i < data.length; i++){
cat = 'Unit ' + data[i].unit;
if(xCategories.indexOf(cat) === -1){
xCategories[xCategories.length] = cat;
}
}
for(i = 0; i < data.length; i++){
if(seriesData){
var currSeries = seriesData.filter(function(seriesObject){ return seriesObject.name == data[i].status;});
if(currSeries.length === 0){
currSeries = seriesData[seriesData.length] = {name: data[i].status, data: []};
} else {
currSeries = currSeries[0];
}
var index = currSeries.data.length;
currSeries.data[index] = data[i].val;
} else {
seriesData[0] = {name: data[i].status, data: [data[i].val]}
}
}
现在您已seriesData
和xCategories
,您可以使用类似于
chart = new Highchart({chart: {renderTo: 'chart-div',
type: 'column'
},
plotOptions: {column: {stacking: 'normal'}},
xAxis:{ categories: xCategories},
series: seriesData
});

在HighCharts网站上,我导航到演示库&gt; HighChart演示部分,然后单击页面左侧的Stacked列。从那里他们有一个JSFiddle with a demo的链接,从那里我看到了两段与你相关的代码。
第一部分是HighChart对象的xAxis
属性。以下是我将其更改为:
xAxis: {
categories: ['Unit A', 'Unit B']
}
这些将是您正在堆叠数据的每个列。
下一部分是series
属性。您可以在此处将要查看的数据传递到这些列中。它看起来像这样:
series: [{
name: 'Stopped / Idle',
data: [21.2022222222222222, 334.7358333333333333]
}, {
name: 'Working',
data: [53.3066666666666667, 212.6386111111111111]
}, {
name: 'Headland Turning',
data: [0.04694444444444444444, 26.2955555555555556]
}, {
name: 'Transport',
data: [5.1425000000000000, 0.00444444444444444444]
}]
在此部分中,您可以指定特定数据类型的名称,然后指定您在xAxis
属性中指定的每列的值。
我非常快速地使用了一些选项,而且你可以做更多的事情,但here's the JSFiddle有一个堆积的柱状图和你的数据。
希望这有帮助!
