js，我用的是v3.js 我很确定我的图表的问题出在我的 x 轴上。我有这样的结构：[ {date: "OCT 2020", close: 57370} {date: "SEP 2020", close: 60100} {date: "AGO 2020", close: 62530} {date: "JUL 2020", close: 68840} {date: "MAY 2020", close: 91470} {date: "ABR 2020", close: 54130} {date: "MAR 2020", close: 57960} {date: "FEB 2020", close: 55720} {date: "ENE 2020", close: 54360}]轴x将是键“日期”，并且 是y-axis，close我不知道如何定义 ，x-axis以便每个表示 x 轴的值将是一个标签。（我的x轴上不会重复任何值，并且我的数据已排序）我依赖这个例子： https://bl.ocks.org/d3noob/4414436我该如何修复它？

这是工作代码：： http://plnkr.co/edit/pdjNBWCYd91drndL ?open=lib%2Fscript.js
这是使用 D3v3，您可能需要升级 D3 版本并浏览 D3docs，因为最新的 D3 版本中有很多更改。
以下是使用您的数据的基本工作示例
<!DOCTYPE html>
<meta charset="utf-8">
<style> /* set the CSS */
body { font: 12px Arial;}
path {
stroke: steelblue;
stroke-width: 2;
fill: none;
}
.axis path,
.axis line {
fill: none;
stroke: grey;
stroke-width: 1;
shape-rendering: crispEdges;
}
</style>
<body>
<!-- load the d3.js library -->
<script src="https://cdnjs.cloudflare.com/ajax/libs/d3/3.5.17/d3.min.js"></script>
<script>
// Set the dimensions of the canvas / graph
var margin = {top: 30, right: 20, bottom: 30, left: 50},
width = 600 - margin.left - margin.right,
height = 270 - margin.top - margin.bottom;
// Set the ranges
var x = d3.scale.ordinal().domain(["OCT 2020",
"SEP 2020",
"AGO 2020",
"JUL 2020",
"MAY 2020",
"ABR 2020",
"MAR 2020",
"FEB 2020",
"ENE 2020"])
.rangePoints([0, width]);
var y = d3.scale.linear().range([height, 0]);
// Define the axes
var xAxis = d3.svg.axis().scale(x)
.orient("bottom").ticks(100);
var yAxis = d3.svg.axis().scale(y)
.orient("left").ticks(10);
// Define the line
var valueline = d3.svg.line()
.x(function(d) { return x(d.date); })
.y(function(d) { return y(d.close); });
// Adds the svg canvas
var svg = d3.select("body")
.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 + ")");
// Get the data
let data=[
{date: "OCT 2020", close: 57370},
{date: "SEP 2020", close: 60100},
{date: "AGO 2020", close: 62530},

{date: "FEB 2020", close: 55720},
{date: "ENE 2020", close: 54360}
]
// Scale the range of the data
// x.domain(d3.extent(data, function(d) { return d.date; }));
y.domain([0, d3.max(data, function(d) { return d.close; })]);
// Add the valueline path.
svg.append("path")
.attr("class", "line")
.attr("d", valueline(data));
// Add the X Axis
svg.append("g")
.attr("class", "x axis")
.attr("transform", "translate(0," + height + ")")
.call(xAxis);
// Add the Y Axis
svg.append("g")
.attr("class", "y axis")
.call(yAxis);
</script>
