小编row*_*oat的帖子

参考Mike Bostock 的这个示例，我想将相同的想法应用于 X 和 Y 切换的条形图。所以标签沿着 Y 轴上下运行。

在这个小提琴中：http : //jsfiddle.net/2eLW6/我只是从 Mike 的示例中复制 wrap 函数并将其应用于我的图表。

function wrap(text, width) {
text.each(function() {
  var text = d3.select(this),
        words = text.text().split(/\s+/).reverse(),
        word,
        line = [],
        lineNumber = 0,
        lineHeight = 1.1, // ems
        y = text.attr("y"),
        dy = parseFloat(text.attr("dy")),
        tspan = text.text(null).append("tspan").attr("x", 0).attr("y", y).attr("dy", dy + "em");
    while (word = words.pop()) {
      line.push(word);
      tspan.text(line.join(" "));
      if (tspan.node().getComputedTextLength() > width) {
        line.pop();
        tspan.text(line.join(" "));
        line = [word];
        tspan = …

这是我的代码:

function toggleClass(element, className){
  d3.select(element).classed(className, !d3.select(element).classed(className));
}

d3.selectAll("rect").on("click", toggleClass(this, "clicked");

我无法让它工作,似乎将参数传递给DOM事件是坏消息.有谁知道解决这个问题？

谢谢

这是关于jsfiddle的项目:http://jsfiddle.net/mLnB3/

我有这种格式的数据:

var data = [
{
    "category": "Category1",
    "subcategories": [
        {

                    "count": 8,
                },
                {
                    "comment": "1Acomment2",
