使现有垂直条形图水平

Question

我有一个现有的条形图，工作正常。

但我想通过翻转轴将其设为水平。

完整代码：

$(document).ready(function() {
  render_chart();
});

function render_chart() {
  var stack = d3.stack;
  var dataset = {
    "categories": ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday'],
    "series": ["Group1", "Group2", "Group3"],

我试图这样做，但我每次都把它搞砸了。当我试图通过改变下面刚刚反转x和y的部分来翻转轴时，它没有正确显示：

var xAxis = d3.axisBottom(xScale)
    .tickSize(7)
    .tickPadding(6);

 var yAxis = d3.axisLeft(yScale).ticks(24);

我无法弄清楚这一点。

为什么 ：

因此，当它们处于水平状态时，我可以在每组条形图中放入更多的东西，因为它们会很长并且内部空间更大。
