绘制水平柱状图表的方法也不是很难，首先在svg中插入g，然后在g中插入rect。
1.html代码
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title></title>
</head>
<body>
<div id="container"></div>
</body>
<script type="text/javascript" src="js/d3.js" ></script>
<script type="text/javascript" src="js/shuzhuangtu.js" ></script>
</html>
2.js代码
var data = [1,3,4,6,2,9,7,3,8],
bar_height = 50,
bar_padding = 10,
svg_width = 500,
svg_height = (bar_height +bar_padding)*data.length;
var scale = d3.scale.linear()
.domain([0, d3.max(data)])
.range([0, svg_width]);
var svg = d3.select("#container")
.append("svg")
.attr("width", svg_width)
.attr("height", svg_height)
var bar = svg.selectAll("g")
.data(data)
.enter()
.append("g")
.attr("transform",function(d, i){return "translate(0, "+i*(bar_height+bar_padding)+")"})
bar.append("rect")
.attr({
"width":function(d){return scale(d);},
"height":bar_height
})
.style("fill","cornflowerblue")
bar.append("text")
.text(function(d){return d;})
.attr({
"x":function(d){return scale(d)},
"y":bar_height/2,
"text-anchor":"end"
})
