d3.js - 如何绘制堆积条形图的x轴

时间:2014-01-31 11:25:15

标签: d3.js

我将x轴作为时间刻度而不是序数刻度添加到堆积条形图中,并将月 - 月格式作为值。 x轴上的刻度线未正确对齐:

我的代码是:

此代码中的错误是什么?如何将x轴标签与条形对齐?

我的csv数据是:

date,scanned,unscanned,compid,sbu
01/2014,10,90,101,f&r
02/2014,55,40,101,f&r
03/2014,45,23,101,f&r
04/2014,65,35,101,f&r
05/2014,100,20,101,f&r
06/2014,50,30,101,f&r
07/2014,10,90,101,f&r
08/2014,22,48,101,f&r
09/2014,0,100,101,f&r
10/2014,3,97,101,f&r
11/2014,22,60,101,f&r
12/2014,57,37,101,f&r

我做了以下更改:

x = d3.time.scale().range([1, 80]);

另外

var rect = cause.selectAll("rect")
      .data(Object)
    .enter().append("svg:rect")
      .attr("id", function(d,i) { return i + " comp " + d.z;  })
      .attr("x", function(d,i) { 
                        if (i ==0) 
                        { 
                            return x(d.x) ;
                        } 
                        else 
                        {
                            return x(d.x);
