我希望得到10的间隔，从0开始直到50.但我得到间隔为5。
这是代码
<!DOCTYPE html>
<html>
<head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/d3/3.5.12/d3.min.js"></script>
</head>
<body>
<script>
var xAxis = d3.svg.axis();
var axisScale = d3.scale.linear()
.domain([0,100])
.range([0,100]);
var xAxis = d3.svg.axis()
.scale(axisScale);
typeof(xAxis);
var svgContainer = d3.select("body").append("svg")
.attr("width", 700)
.attr("height", 100);
//Create the Scale we will use for the Axis
var axisScale = d3.scale.linear()
.domain([0, 50])
.range([0, 400]);
//Create the Axis
var xAxis = d3.svg.axis()
.scale(axisScale);
//Create a group Element for the Axis elements and call the xAxis function
var xAxisGroup = svgContainer.append("g")
.call(xAxis);
</script>
</body>
任何形式的帮助将不胜感激。谢谢。
在D3轴中指定值的最安全方法是使用axis.tickValues。在你的情况下：
.tickValues(d3.range(axisScale.domain()[0], axisScale.domain()[1] + 10, 10));
以下是您更改的代码：
var svgContainer = d3.select("body").append("svg")
.attr("width", 700)
.attr("height", 100);
var axisScale = d3.scale.linear()
.domain([0, 50])
.range([0, 400]);
var xAxis = d3.svg.axis()
.scale(axisScale)
.tickValues(d3.range(axisScale.domain()[0], axisScale.domain()[1] + 10, 10));
var xAxisGroup = svgContainer.append("g")
.attr("transform", "translate(20,50)")
.call(xAxis);path,
line {
fill: none;
stroke: black;
