无法放大 D3 图形
[英]Can't make a zoom on D3 graph
问题描述
I tried out many ways to create a zoom to my D3 graph working with the roots.
我尝试了很多方法来为我的 D3 图形创建缩放，并使用根。 By that I mean giving the option of zoom in and zoom out for the nodes circles from the root.我的意思是提供放大和缩小节点圆圈的选项。
<style>
.node circle {
fill: #fff;
stroke: steelblue;
stroke-width: 1.5px;
}
.node {
font: 10px sans-serif;
}
.link {
fill: none;
stroke: #ccc;
stroke-width: 1.5px;
}
</style>
The script:脚本：
<script>
var diameter = 960;
var tree = d3.layout.tree()
.size([360, diameter / 2 - 120])
.separation(function (a, b) { return (a.parent == b.parent ? 1 : 2) / a.depth; });
var diagonal = d3.svg.diagonal.radial()
.projection(function (d) { return [d.y, d.x / 180 * Math.PI]; });
var svg = d3.select("body").append("svg")
.attr("width", diameter)
.attr("height", diameter - 150)
.append("g")
.attr("transform", "translate(" + diameter / 2 + "," + diameter / 2 + ")");
d3.json("json.json", function (error, root) {
if (error) throw error;
var nodes = tree.nodes(root),
links = tree.links(nodes);
var link = svg.selectAll(".link")
.data(links)
.enter().append("path")
.attr("class", "link")
.attr("d", diagonal);
var node = svg.selectAll(".node")
.data(nodes)
.enter().append("g")
.attr("class", "node")
.attr("transform", function (d) { return "rotate(" + (d.x - 90) + ")translate(" + d.y + ")"; })
/*this will change the color of the class node to red*/
.on('mouseover', function (d) {
var nodeSelection = d3.select(this).style("fill", "red");
})
node.append("circle")
.attr("r", 4.5);
node.append("text")
.attr("dy", ".31em")
.attr("text-anchor", function (d) { return d.x < 180 ? "start" : "end"; })
.attr("transform", function (d) { return d.x < 180 ? "translate(8)" : "rotate(180)translate(-8)"; })
.text(function (d) { return d.name; });
/*try out*/
});
</script>

Append a container group element to the graph and set its class name as 'drawArea'.将容器组元素附加到图形并将其类名设置为“drawArea”。 Now add following code.现在添加以下代码。
d3.select("svg")
.call(d3.behavior.zoom()
.scaleExtent([0.5, 5])
.on("zoom", zoom));
function zoom() {
var h = w = diameter * 2;
var scale = d3.event.scale,
translation = d3.event.translate,
tbound = -h * scale,
bbound = h * scale,
lbound = -w * scale,
rbound = w * scale;
// limit translation to thresholds
translation = [
Math.max(Math.min(translation[0], rbound), lbound),
Math.max(Math.min(translation[1], bbound), tbound)
];
d3.select(".drawArea")
.attr("transform", "translate(" + translation + ")" +
" scale(" + scale + ")");
}
