我想构建一个带有多个系列和折线图的柱形图的组合图表。问题是我从嵌套的JSON响应中获取高图表数据。为此我初始化了数组,并且该数组在plotoptions highcharts中以串联形式给出,如下面的代码所示。
我的代码是这样的:
var crime_data=[];
for(var i=0;i<result.themes.length;i++){
var crime={};
var test2 = result.themes[i];
var test = test2[Object.keys(test2)];
crime.name = Object.keys(result.themes[i]);
crime.data = [];
for(var k=0;k<test.yearTheme.length;k++){
var test3=test.yearTheme[k];
var test5=test3.individualValueVariable;
for(var j=0;j<test5.length;j++){
crime.data.push(test5[j].count);
};
};
crime_data.push(crime);
};
var crimeChart = new Highcharts.Chart({
chart: {
renderTo: 'container1',
type:'column'
},
title: {
text: 'Crime'
},
xAxis: {
categories: month,
crosshair: true
},
yAxis: {
min: 0,
title: {
text: 'Count'
}
},
credits: {
enabled: false
},
tooltip: {
shared: true,
},
plotOptions: {
column: {
pointPadding: 0.2,
borderWidth: 0,
depth: 25,
allowPointSelect: true,
cursor: 'pointer',
point: {
},
}
},
series: crime_data
});
这是我的线图,当我将类型列更改为高图中的图表样条线时,我得到了。
这是我的JSON数据(Highcharts数据):
{
"boundaries": {
"boundary": [
{
"boundaryId": "55083021003",
"boundaryType": "USA_CITY",
"boundaryRef": "C1"
}
]
},
"themes": [
{
"AssaultCrimeTheme": {
"boundaryRef": "C1",
"individualValueVariable": [
{
"name": "2013 Assault Crime",
"description": "Assault Crime for 2013",
"count": 18901
},
{
"name": "2014 Assault Crime",
"description": "Assault Crime for 2014",
"count": 17707
}
]
}
},
{
"BurglaryCrimeTheme": {
"boundaryRef": "C1",
"individualValueVariable": [
{
"name": "2013 Burglary Crime",
"description": "Burglary Crime for 2013",
"count": 17743
},
{
"name": "2014 Burglary Crime",
"description": "Burglary Crime for 2014",
"count": 14242
}
]
}
}
]
}
我想在同一容器中将它们组合在一起,具有相同的数据。问题在于如何告诉highcharts多个系列应该用line表示,列类型用相同的数据表示。当我写这个系列时:[{ data:crime_data,type:spline}]而不是series:crime_data在这种情况下,我没有得到Highcharts数据。任何人都可以帮我,我该怎么做。请建议我。

以下是使用您的数据的完整示例。
const json = {
"boundaries": {
"boundary": [{
"boundaryId": "55083021003",
"boundaryType": "USA_CITY",
"boundaryRef": "C1"
}]
},
"themes": [{
"AssaultCrimeTheme": {
"boundaryRef": "C1",
"individualValueVariable": [{
"name": "2013 Assault Crime",
"description": "Assault Crime for 2013",
"count": 18901
}, {
"name": "2014 Assault Crime",
"description": "Assault Crime for 2014",
"count": 17707
}]
}
}, {
"BurglaryCrimeTheme": {
"boundaryRef": "C1",
"individualValueVariable": [{
"name": "2013 Burglary Crime",
"description": "Burglary Crime for 2013",
"count": 17743
}, {
"name": "2014 Burglary Crime",
"description": "Burglary Crime for 2014",
"count": 14242
}]
}
}]
}
// Create categories object in order filter duplicates
const cats = {}
const series = json.themes.map((o) => {
const key = Object.keys(o)[0]
return {
name: key,
data: o[key].individualValueVariable.map((o) => {
cats[o.name] = 1
return { category: o.name, y: o.count }
})
}
})
// Convert categories object to array
const categories = Object.keys(cats)
// Chart options
const options = {
chart: {type: 'column'},
xAxis: {categories: categories},
series: series
}
// Create chart
const chart = Highcharts.chart('container', options)
console.log(series, categories)
