问题描述
我有一系列用高图形绘制的线图,并且它们之间共享工具提示。
$('# (
tooltip:{
shared:true
},
series:[{
name:'Berlin',
data :[-0.9,0.6,3.5,8.4,13.5,17.0,18.6,17.9,14.3,9.0,3.9,1.0]
},{
名称:'伦敦',
数据:[-0.9,0.6,3.5,8.4,13.5,17.0,18.6,17.9,14.3,9.0,3.9,1.0] [3.9,4.2,5.7,8.5,11.9,15.2,17.0,16.6,14.2,10.3,6.6,4.8]
}]
});
捕获dblclick事件并在图形上获取悬停y轴值的最佳方法是什么?
解决方案
这在 。
所以你必须在你的代码中加入这样的内容:
图表:{
events:{
click:function(event){
alert(
'x:'+ Highcharts.dateFormat('%Y-%m-% d',event.xAxis [0] .value)+','+
'y:'+ event.yAxis [0] .value
);
$ b 这是一个。
更新
为确保点击图形本身也已启用,请添加以下内容:
plotOptions:{
series:{
cursor:'pointer',
point:{
events:{
click:function(){
alert ('Category:'+ this.category +',value:'+ this.y);
}
}
}
}
},
你可以看到一个有效的例子
I have a series of line graph plotted with highcharts and the tooltip is shared among them.
$('#container').highcharts({
tooltip: {
shared: true
},
series: [{
name: 'Berlin',
data: [-0.9, 0.6, 3.5, 8.4, 13.5, 17.0, 18.6, 17.9, 14.3, 9.0, 3.9, 1.0]
}, {
name: 'London',
data: [3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8]
}]
});
What should be the best way to capture the dblclick event and obtain the hover y axis value on the graph ?
解决方案 This is explained fairly well in the documentation.
What you can do is something similar to THIS.
So you have to add something like this to your code:
chart: {
events: {
click: function(event) {
alert (
'x: '+ Highcharts.dateFormat('%Y-%m-%d', event.xAxis[0].value) +', ' +
'y: '+ event.yAxis[0].value
);
}
}
}
Here is an example of that implementation.
Update
To ensure clicking on the graph itself is also enabled, add the following:
plotOptions: {
series: {
cursor: 'pointer',
point: {
events: {
click: function() {
alert ('Category: '+ this.category +', value: '+ this.y);
}
}
}
}
},
