Tec*_*ude 56 responsive-design d3.js
我有这个D3图表 - 几乎开箱即用.有没有办法让它响应并使用宽度和高度变量,innerRadius和outerRadius的百分比？我在响应式网站上工作,需要根据屏幕大小/浏览器大小进行更改.

setInterval(function() {

function arcTween(transition, newAngle) {
transition.attrTween("d", function(d) {

return function(t) {
d.endAngle = interpolate(t);
return arc(d);

您可以使用SVG元素的组合viewBox和preserveAspectRatio属性调整图表大小.
请参阅此jsfiddle以获取完整示例:http://jsfiddle.net/BTfmH/12/
var svg = d3.select('.chart-container').append("svg")
.attr("width", '100%')
.attr("height", '100%')
.attr('viewBox','0 0 '+Math.min(width,height)+' '+Math.min(width,height))
.attr('preserveAspectRatio','xMinYMin')
.append("g")
.attr("transform", "translate(" + Math.min(width,height) / 2 + "," + Math.min(width,height) / 2 + ")");
您甚至不需要resize使用此方法的处理程序.
您可以使用window.innerWidth和window.innerHeight获取屏幕的尺寸并相应地设置图表,例如
var width = window.innerWidth,
height = window.innerHeight,
innerRadius = Math.min(width,height)/3,
outerRadius = innerRadius + 30;
