javascript - Equal Space between the legends in d3 -

i newbie in using d3 library, trying have equal space between legends. in current stage of work -attached- not provide equal spaces.

i know how able fix.

here code have far:

var margin = { top: 20, right: 50, bottom: 30, left: 60 };      self.drawlegends = function () {              var legenddata = [{ "color": "blue", text: "normal distribution" }, { color: "green", text: " ave a" }, { color: "red", text: "ave b" }]             var legends = self.svg.selectall("g legends").data(legenddata);             var legendbox = legends.enter()                  .append("g")                  .attr("transform", function (d, i) { return "translate(" + parsefloat((i + 1) * (($("#chart").width() - margin.left - margin.right) / 4)) + ",-10)" })          var circles = legendbox.append("circle")             .attr("r", 5)             .attr("stroke", "black")             .attr("fill", function (d, i) { return d.color })          legendbox.append("text")            .attr("dx", function (d) { return 10 })            .attr("dy", function (d) { return 5 })            .attr("fill","white")            .text(function (d) { return d.text })     }, 

here's updated fiddle think you're after: http://jsfiddle.net/henbox/7le4tc92/2/

when first draw circle , text in each g element, don't use transform. then, select each g , text length (using getcomputedtextlength()) calculate translation want:

svg.selectall("g")     .attr("transform", function (d, i) {         var x_pos = d3.select(this).select("text").node().getcomputedtextlength() + 20;         x_offset = x_offset + x_pos;             return "translate(" + (x_offset - x_pos + margin.left) + ", 20)"     })
