ここに私のコードhttp://jsfiddle.net/qkHK6/2174/へのリンクがあります。矩形の外側の領域を隠したり、クリップしたりしたいのですが、バーはy軸の左側に移動するので、そのエリアをクリップしたいと思います。誰か助けてください。異なる年齢のためD3.js - グループ化された棒グラフをズームインするときに矩形外の領域をクリップする方法
var color = d3.scale.ordinal()
.range(["#98abc5", "#8a89a6", "#7b6888", "#6b486b", "#a05d56", "#d0743c", "#ff8c00"]);
creating axis and bar graph
VAR X軸= d3.svg.axis（） .scale（X0） .orient（ "底部"）を使用
var margin = {

},
width = 300 - margin.left - margin.right,
height = 400 - margin.top - margin.bottom;
