使垂直條形圖垂直

Question

我正在嘗試根據此示例http://bl.ocks.org/mbostock/1283663創建垂直層次條形圖。 我能夠定位軸，但似乎無法將條形圖從圖表的底部而不是頂部開始移動。 有人可以幫忙嗎？

var margin = {top: 30, right: 120, bottom: 30, left: 120},
 width = 600 - margin.left - margin.right,
 height = 300 - margin.top - margin.bottom;

var y = d3.scale.linear()
  .range([height,0]);

var barWidth = 20;

var color = d3.scale.ordinal()
   .range(["steelblue", "#ccc"]);

var duration = 750,
  delay = 25;

var partition = d3.layout.partition()
  .value(function(d) { return d.size; });

var yAxis = d3.svg.axis()
   .scale(y)
   .orient("left");

 var xAxis = d3.svg.axis()
   .scale(barWidth)
   .orient("botom");

 var svg = d3.select(".sales-pipeline-chart").append("svg:svg")
  .attr("width", width + margin.left + margin.right)
  .attr("height", height + margin.top + margin.bottom)
.append("g")

我能夠移動這些條，因此它們現在從底部開始，但是動畫仍然存在一些問題。 向上鑽取不起作用，我也想將文本移到xAxis下方。

var margin = {top: 30, right: 120, bottom: 30, left: 120},
 width = 600 - margin.left - margin.right,
 height = 300 - margin.top - margin.bottom;

 var y = d3.scale.linear()
      .range([height,0]);

 var barHeight = 40;

 var color = d3.scale.ordinal()
    .range(["steelblue", "#ccc"]);

 var duration = 750,
   delay = 25;

 var partition = d3.layout.partition()
    .value(function(d) { return d.size; });

 var yAxis = d3.svg.axis()
    .scale(y)
    .orient("left");

 var xAxis = d3.svg.axis()
    .scale(barHeight)
    .orient("botom");

 var svg = d3.select(".sales-pipeline-chart").append("svg:svg")
    .attr("width", width + margin.left + margin.right)
    .attr("height", height + margin.top + margin.bottom)
   .append("g")
    .attr("transform", "translate(" + margin.right + "," + margin.top + ")");

 svg.append("rect")
   .attr("class", "background")
   .attr("width", width)
