所以我正在处理D3.js中的气泡图:http://bl.ocks.org/mbostock/4063269。宽度和高度由直径决定。所以我问:如何制作这个SVG泡泡云,以及任何其他SVG响应尽可能少的重新编码?
<script>
var diameter = 628,
format = d3.format(",d"),
color = d3.scale.ordinal()
.range(["#FFFFFF", "#7ec0ee", "#0D2A46"]);
var bubble = d3.layout.pack()
.sort(null)
.size([diameter, diameter])
.padding(1.5);
function addChart(file, target){
var svg = d3.select("body").append("svg")
.attr("width", diameter)
.attr("height", diameter)
.attr("class", "bubble");
d3.json(file, function(error, root) {
var node = svg.selectAll(".node")
.data(bubble.nodes(classes(root))
.filter(function(d) { return !d.children; }))
.enter().append("g")
.attr("class", "node")
.attr("transform", function(d) { return "translate(" + d.x + "," + d.y + ")"; });
node.append("title")
.text(function(d) { return d.className + ": " + format(d.value); });
node.append("circle")
.attr("r", function(d) { return d.r; })
.style("fill", function(d) { return color(d.packageName); });
node.append("text")
.attr("dy", ".3em")
.style("text-anchor", "middle")
.text(function(d) { return d.className.substring(0, d.r / 3); });
});
}
addChart("DataGreatEnglishWriters.json", "dv.foo");
addChart("Dubliner.json", "div.bar");
addChart("2LeftFeet.json", "div.head");
// Returns a flattened hierarchy containing all leaf nodes under the root.
function classes(root) {
var classes = [];
function recurse(name, node) {
if (node.children) node.children.forEach(function(child) { recurse(node.name, child); });
else classes.push({packageName: name, className: node.name, value: node.size});
}
recurse(null, root);
return {children: classes};
}
d3.select(self.frameElement).style("height", diameter + "px");
</script>
答案 0 :(得分:4)
这是你提到的Mike的例子FIDDLE。
var chart = $(".bubble"),
aspect = chart.width() / chart.height(),
container = chart.parent();
$(window).on("resize", function() {
var targetWidth = container.width();
chart.attr("width", targetWidth);
chart.attr("height", Math.round(targetWidth / aspect));
}).trigger("resize");
基本上,您使用viewBox
上的preserveAspectRatio
和svg
属性并相应地重新调整大小。
