- 下定决心,好好过一天~
这里我的d3是v7版本,框架使用的是vue框架。可以只看methods中写的代码即可
源代码
<template>
<div id="ChordChartsD3" width=600 height=600></div>
</template>
<script>
import * as d3 from "d3"
export default {
name:"ChordChartsD3",
mounted(){
this.ChordChartsD3();
},
methods:{
ChordChartsD3(){
var dataAll = [{
source:{
startAngle: 0.2,
endAngle: Math.PI * 0.3,
// radius: 100
},
target:{
startAngle: Math.PI*1.0,
endAngle: Math.PI*1.6,
// radius: 100
}
}];
var matrix = [
[ 10, 20 , 20 , 30 , 40 ], // 节点1
[ 5, 15 , 55 , 10 , 10 ], // 节点2
[ 20, 5 , 80 , 5 , 5 ], // ...
[ 10, 20 , 20 , 30 , 40 ],
]
var svgWidth = 600,svgHeight = 600;
var svg = d3.select("#ChordChartsD3")
.append("svg")
.attr("width",svgWidth)
.attr("height",svgHeight);
var chord = d3.chord()(matrix);
var ribbon = d3.ribbon().radius(200);
var colors = d3.schemeSet3;
function updateCharts(){
svg.selectAll("path")
.data(chord)
.enter()
.append("path")
.attr("d",ribbon)
.attr("transform","translate(200,200)")
.attr('fill', ({
source: {
index } }) => colors[index])
.attr('stroke', ({
source: {
index } }) => d3.rgb(colors[index]).darker())
.on('mouseover', function (d, i) {
// console.log(d);
// console.log(i);
// console.log(i.source.index);
d3.select(this)
.attr('fill', d3.rgb(colors[i.source.index]).darker())
})
.on('mouseout', function (d,i) {
// console.log(d);
// console.log(i);
d3.select(this)
.attr('fill', colors[i.source.index])
});
}
updateCharts();
}
}
}
