【问题描述】:
我复制了下面的 sn-p 表单 D3 (https://www.d3-graph-gallery.com/graph/arc_highlight.html) 来创建弧形图
var margin = { top: 20, right: 30, bottom: 20, left: 30},
width = 1100 - margin.left - margin.right,
height = 400 - margin.top - margin.bottom;
// append the svg object to the body of the page
var svg = d3.select("#my_dataviz")
.append("svg").attr("width", width + margin.left + margin.right).attr("height", height + margin.top + margin.bottom)
.append("g") .attr("transform", "translate(" + margin.left + "," + margin.top + ")");
var data = { "nodes": [{ "id": 1, "name": "uto-ujamaki"}, {"id": 2, "name": "saske-uchiha"}.......], "links": [{"source": 1, "target": 2}, {"source": 1, "target": 5 }......]};
// List of node names
var allNodes = data.nodes.map(function(d){ return d.name })
// A linear scale to position the nodes on the X axis
var x = d3.scalePoint().range([0, width]).domain(allNodes)
// Add the circle for the nodes
var nodes = svg.selectAll("mynodes").data(data.nodes).enter().append("circle")
.attr("cx", function(d){ return(x(d.name))})
.attr("cy", height-30).attr("r", 8)
.style("fill", "#69b3a2")
// And give them a label
var labels = svg.selectAll("mylabels").data(data.nodes).enter().append("text")
.attr("x", function(d){ return(x(d.name))})
.attr("y", height-10)
.text(function(d){ return(d.name)})
.style("text-anchor", "middle")
// <------ below attribute, it work but rotate whole x-axis instead of node text ---->
// .attr("transform", "translate(250, 0) rotate(60)")
现在 x 轴有水平放置的标签,当有大量数据/节点时,它会重叠。
我想将轴上的文本旋转一定程度(比如 60 度)以避免重叠,但是当我添加变换属性时,它会将整个轴而不是节点文本旋转 60 度。我是造型新手。
