目前正试图在我的图表上包装一些文字标签。我跟随Mike Bostock的例子here。当我尝试实现他的例子时,它适用于我的y轴,但我需要它在我的x轴上工作,我不确定它为什么不起作用。
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;
}

小变化,你实际上并没有在x轴刻度文本上调用wrap
(你只是为y轴标签调用它)。
您需要将最后两行添加到此块中,其中附加了x轴
//draw the bars
chart2.append("g")
.attr("class", "x axis")
.attr("transform", "translate(0," + height + ")")
.call(xAxis)
.selectAll(".tick text")
.call(wrap, x0.rangeBand());

或者你可以使用带有html的外来对象:
var fo = nodes.append("foreignObject")
.style("pointer-events", "none")
.attr("id", "fo")
.attr("width", function(d) {
return Math.max(32, this.getComputedTextLength() + 12);
});
fo.append("xhtml:body")
.style("text-align", "center")
.append("div")
.attr("class", "fotext")
.style("margin", "0px auto")
.style("font", "14px 'Helvetica Neue'")
.style("overflow", "auto")
.html(function(d) {
return d.name
});
fo.attr("transform", function(d) {
return translateInMiddle(this)
});
function translateInMiddle(object) {
bbox = object.getBBox();
return "translate(" + [-bbox.width / 2, -bbox.height / 8] + ")";
}
