2.js代码
var data = [1,3,4,6,2,9,7,3,8],
bar_width = 50,
bar_padding = 10,
svg_height = 500,
svg_width = (bar_width +bar_padding)*data.length;
var scale = d3.scale.linear()
.domain([0, d3.max(data)])
.range([svg_height, 0]);
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("+i*(bar_width+bar_padding)+", 0)"})
bar.append("rect")
.attr({
"y":function(d){return scale(d);},
"width":bar_width,
"height":function(d){return svg_height-scale(d);}
})
.style("fill","cornflowerblue")
bar.append("text")
.text(function(d){return d;})
.attr({
"y":function(d){return scale(d)},
"x":bar_width/2,
"dy":15,
