$(函数()
{
var barChart=new CanvasJS.Chart(“barChartContainer”,
{
animationEnabled:没错,
主题:“light2”,
标题:
{
文本:“按性别区分的员工长度”,
尺寸:20,
fontFamily:“投石机MS”,
fontWeight:“粗体”,
差额:10
},
axisY:{
标题:“雇员人数”
},
数据:[{
类型:“漏斗”,//列饼图漏斗线
数据点:[
{y:${male},标签:“male”},
{y:${female},标签:“female”}
]
}]
});
render();
}
});
$(“#饼”)。单击(函数()
{
警报(“已单击饼”);
});
$(“#条”)。单击(函数()
{
警报(“已单击条”);
});
$(“#漏斗”)。单击(函数()
{
警报(“漏斗被点击”);
});
调用渲染后,
我们可以按如下方式访问数据系列类型
barChart.options.data[0].type = 'pie';
而不是有三个单独的点击事件,
将单击事件分配给下拉类。
然后使用单击的元素的id设置图表类型
$(".dropdown-item").click(function(e) {
barChart.options.data[0].type = e.target.id;
barChart.render();
});
请参阅以下工作片段
$(函数(){
var barChart=new CanvasJS.Chart(“barChartContainer”{
animationEnabled:没错,
主题:“light2”,
标题:{
文本:“按性别区分的员工长度”,
尺寸:20,
fontFamily:“投石机MS”,
fontWeight:“粗体”,
差额:10
},
axisY:{
标题:“雇员人数”
},
数据:[{
类型:“漏斗”,
数据点:[
{y:10,标签:“男性”},
{y:10,标签:“女性”}
]
}]
});
render();
$(“.dropdown item”)。单击(函数(e){
barChart.options.data[0].type=e.target.id;
render();
});
