Question

我是d3.js的新手，我想根据示例here生成图表。

如果我可以单独存储此文件并运行它可以正常工作。但我不知道如何将其添加到我的html页面的特定元素中。

var margin = {top: 20, right: 30, bottom: 30, left: 40},
    width = 960 - margin.left - margin.right,
    height = 500 - margin.top - margin.bottom;

var y = d3.scale.linear()

svg.append("g")

    .call(yAxis);

svg.append("g")
    .attr("class", "x axis")
    .attr("transform", "translate(0," + height + ")")
    .call(xAxis);

svg.append("g").selectAll("g")
    .data(data)
  .enter().append("g")
    .style("fill", function(d, i) { return z(i); })
    .attr("transform", function(d, i) { return "translate(" + x1(i) + ",0)"; })
  .selectAll("rect")
    .data(function(d) { return d; })
  .enter().append("rect")
    .attr("width", x1.rangeBand())
    .attr("height", y)
    .attr("x", function(d, i) { return x0(i); })
    .attr("y", function(d) { return height - y(d); });
    </script>
  </body>
</html>

从上面的代码＆＃34;这里我想用d3.js＆＃34;绘制图形。在本节中，我想添加我的图表。

在定义SVG变量时，按ID选择此<div>。

首先，给它一个（唯一的）ID：

<div id="svgHere"></div>

然后：

var svg = d3.select("#svgHere")
    .append("svg")
    .attr("width", someValue)//the width value goes here
    .attr("height", someValue);//the height value goes here

如何在特定的<div>部分绘制d3.js图
