我正在尝试使用apexCharts
javascript 库并且在实现单击事件时遇到了麻烦我已经阅读了文档,但是没有关于如何实现它的明确示例。
到目前为止,我有这个代码。
var options = {
chart: {
height: 350,
type: 'bar',
},
plotOptions: {
bar: {
dataLabels: {
position: 'top', // top, center, bottom
},
}
},
dataLabels: {
enabled: true,
formatter: function (val) {
return val + "%";
},
offsetY: -20,
style: {
fontSize: '12px',
colors: ["#304758"]
}
},
series: [{
name: 'Inflation',
data: [2.3, 3.1, 4.0, 10.1, 4.0, 3.6, 3.2, 2.3, 1.4, 0.8, 0.5, 0.2]
}],
xaxis: {
categories: ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"],
position: 'top',
labels: {
offsetY: -18,
},
axisBorder: {
show: false
},
axisTicks: {
show: false
},
crosshairs: {
fill: {
type: 'gradient',
gradient: {
colorFrom: '#D8E3F0',
colorTo: '#BED1E6',
stops: [0, 100],
opacityFrom: 0.4,
opacityTo: 0.5,
}
}
},
tooltip: {
enabled: true,
offsetY: -35,
}
},
fill: {
gradient: {
enabled: false,
shade: 'light',
type: "horizontal",
shadeIntensity: 0.25,
gradientToColors: undefined,
inverseColors: true,
opacityFrom: 1,
opacityTo: 1,
stops: [50, 0, 100, 100]
},
},
yaxis: {
axisBorder: {
show: false
},
axisTicks: {
show: false,
},
labels: {
show: false,
formatter: function (val) {
return val + "%";
}
}
},
title: {
text: 'Monthly PCB Washout Occurrences, 2018',
floating: true,
offsetY: 320,
align: 'center',
style: {
color: '#444'
}
},
active: {
allowMultipleDataPointsSelection: true,
},
events:{
dataPointSelection: function(event, chartContext, config){
console.log(event);
}
}
}
var chart = new ApexCharts(
document.querySelector("#chart"),
options
);
chart.render();
我首先尝试了该click
事件,但发现我正在寻找的dataPointSelection
是当用户单击柱形图/条形图时它将返回元素的事件或数据的方法,知道如何实现吗?任何建议都会很棒!
