包装文本标签 [英] Wrapping text labels

问题描述

目前正尝试在图表上包装一些文字标签。我按照Mike Bostock的示例在这里。当我尝试实现他的例子，它适用于我的Y轴，但我需要它在我的X轴上工作，我不知道为什么它不工作。

Currently trying to wrap some text labels on my graph. I'm following Mike Bostock's example here. When I tried implementing his example it works for my y-axis but I need it to work on my x-axis and I'm not exactly sure why it's not working.

 chart2.append("g")
        .attr("class", "y axis")
        .call(yAxis)
        .append("text")
        .attr("transform", "rotate(-90)")
        .attr("y", 6)
        .attr("dy", ".71em")
        .style("text-anchor", "end")
        .text("Potential Years Lost")
        .call(wrap, x0.rangeBand());


  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 = text.append("tspan").attr("x", 0).attr("y", y).attr("dy", ++lineNumber * lineHeight + dy + "em").text(word);
      }
    }
  });
}

function type(d) {
  d.value = +d.value;
  return d;
}

推荐答案

小改变，你实际上没有在x轴刻度线上调用 wrap （你只是为y轴标签调用它） 。

Small change, you weren't actually calling wrap on the x-axis tick text (you were only calling it for the y-axis label).

您需要将最后两行添加到此x轴所在的块中

You needed to add the final two lines to this block where the x-axis is appended

//draw the bars
chart2.append("g")
    .attr("class", "x axis")
    .attr("transform", "translate(0," + height + ")")
    .call(xAxis)
    .selectAll(".tick text")
    .call(wrap, x0.rangeBand());
