我用两个维度绘制了窗口宽度的图表:
var width = (window.innerWidth < 1280) ? 400 : 600,
height = (window.innerWidth < 1280) ? 400 : 500,
radius = Math.min(width, height) / 2;
var arc = d3.svg.arc().innerRadius(radius).outerRadius(radius - 10),
arcFinal = d3.svg.arc().innerRadius(radius - 100).outerRadius(radius - 10),
arcHover = d3.svg.arc().innerRadius(radius - 100).outerRadius(radius);
var svg = d3.select("#chart").append("svg")
.attr("width", width)
.attr("height", height)
.append("g")
.attr("id", "pie")
.attr("transform", "translate(" + width / 2 + "," + height / 2 + ")");}
在调整大小事件中更新此功能的最佳方法是什么?
