我正在制作Highchart柱形图。
我需要向其添加一个onclick事件,以便单击不同的列时可以获取数据。
这是我当前的完整代码。
var chart;
$(function () {
$.ajax({
url: 'url here',
method: 'GET',
async: false,
success: function(result) {
themainData = result;
}
});
var mainData = [themainData];
var chList=[];
var voList=[];
var coList=[];
for (var i = 0; i < mainData[0].ch.length; i++) {
var obj = mainData[0].ch[i];
var chlst = obj.name;
var vl = obj.st.vo;
var cl = obj.st.co;
chList.push(chlst);
voList.push(vl);
coList.push(cl);
}
var chart = {
type: 'column',
};
var title = {
text: 'Vo and Co'
};
var xAxis = {
categories: chList
};
var yAxis ={
min: 0,
title: {
text: 'Ch'
},
stackLabels: {
enabled: true,
style: {
fontWeight: 'bold',
color: (Highcharts.theme && Highcharts.theme.textColor) || 'gray'
}
}
};
var legend = {
align: 'right',
x: -30,
verticalAlign: 'top',
y: 25,
floating: true,
backgroundColor: (Highcharts.theme && Highcharts.theme.background2) || 'white',
borderColor: '#CCC',
borderWidth: 1,
shadow: false
};
var tooltip = {
formatter: function () {
return '<b>' + this.x + '</b><br/>' +
this.series.name + ': ' + this.y + '<br/>' +
'Total: ' + this.point.stackTotal;
}
};
var plotOptions = {
column: {
stacking: 'normal',
dataLabels: {
enabled: true,
color: (Highcharts.theme && Highcharts.theme.dataLabelsColor) || 'white',
style: {
textShadow: '0 0 3px black'
}
}
}
};
var credits = {
enabled: false
};
var series= [{
name: 'Vo',
data: voList
}, {
name: 'Co',
data: coList
}];
var json = {};
json.chart = chart;
json.title = title;
json.xAxis = xAxis;
json.yAxis = yAxis;
json.legend = legend;
json.tooltip = tooltip;
json.plotOptions = plotOptions;
json.credits = credits;
json.series = series;
$('#container').highcharts(json);
});
如何在此处添加onclick事件?
最佳答案
您可以在图表,系列或点上添加click事件。我认为将click事件添加到系列中对您来说很有意义。
var series= [{
name: 'Vo',
data: voList
events: {
click: function (event) {}
}
}, {
name: 'Co',
data: coList
}];
event.point是单击的点。见http://api.highcharts.com/highcharts/series%3Cbar%3E.events.click
关于javascript - HighCharts堆积的列将Onclick事件添加到图表,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/39494683/
