我需要一个带有d3.js的圆形辐条图。我想在角度js应用程序中添加它。基于Json文件数据,必须绘制图表。我不需要任何动画和缓动效果。请帮忙,找到附图。
我有一个源代码,但我无法删除动画和缓动效果。我只需要静态图。
源代码:
var width = 960,
height = 600,
root;
var force = d3.layout.force()
.linkDistance(200)
.charge(-200)
.gravity(0)
.size([width, height])
.on("tick", tick);
var svg = d3.select("svg").append("svg")
.attr("width", width)
.attr("height", height);
var link = svg.selectAll(".link"),
node = svg.selectAll(".node");
d3.json("graph.json", function(error, json) {
root = json;
update();
});
function update() {
var nodes = flatten(root),
links = d3.layout.tree().links(nodes);
// Restart the force layout.
force
.nodes(nodes)
.links(links)
.start();
// Update links.
link = link.data(links, function(d) { return d.target.id; });
link.exit().remove();
link.enter().insert("line", ".node")
.attr("class", "link");
// Update nodes.
node = node.data(nodes, function(d) { return d.id; });
node.exit().remove();
var nodeEnter = node.enter().append("g")
.attr("class", "node")
.on("click", click)
.call(force.drag)
.attr("href", function(d) { return d.link; });
nodeEnter.append("svg:a")
.attr("xlink:href", function(d){return d.link;})
.append("circle")
.attr("r", function(d) { return Math.sqrt(d.size) / 10 || 4.5; });
nodeEnter.append("text")
.attr("dy", ".35em")
.text(function(d) { return d.name; });
node.select("circle")
.style("fill", color);
}
function tick() {
link.attr("x1", function(d) { return d.source.x; })
.attr("y1", function(d) { return d.source.y; })
.attr("x2", function(d) { return d.target.x; })
.attr("y2", function(d) { return d.target.y; });
node.attr("transform", function (d) { return "translate(" + d.x + "," + d.y + ")"; });
node.forEach(function (d) {
if (d._children || d.children) {
d.x = width / 2, d.y = height / 2;
d.fixed = true;
}
});
}
function color(d) {
return d._children ? "#3182bd" // collapsed package
: d.children ? "#2F9BC1" // expanded package
: "#fd8d3c"; // leaf node
}
// Toggle children on click.
function click(obj) {
if (d3.event.defaultPrevented) return; // ignore drag
if (d.children) {
d._children = d.children;
d.children = null;
} else {
d.children = d._children;
d._children = null;
}
update();
}
// Returns a list of all nodes under the root.
function flatten(root) {
var nodes = [], i = 0;
function recurse(node) {
if (node.children) node.children.forEach(recurse);
if (!node.id) node.id = ++i;
nodes.push(node);
}
recurse(root);
return nodes;
}
