title: How do you change the width of a Y-axis in a D3 chart?
body: <p>I have a simple, working bar chart in D3, configured as follows:</p>
  
  <pre><code>&lt;script&gt;
  
  var margin = {top: 20, right: 20, bottom: 70, left: 40},
      width = 600 - margin.left - margin.right,
      height = 300 - margin.top - margin.bottom;
  
  // Parse the date / time
  var parseDate = d3.time.format("%Y-%m").parse;
          //var format = d3.timeFormat("%Y-%m");
  
  var x = d3.scale.ordinal().rangeRoundBands([0, width], .05);
  
  var y = d3.scale.linear().range([height, 0]);
  
  var xAxis = d3.svg.axis()
      .scale(x)
      .orient("bottom")
      .tickFormat(d3.time.format("%Y-%m"));
  
  var yAxis = d3.svg.axis()
      .scale(y)
      .orient("left")
      .ticks(10);
  
          var svg = d3.select("#arrChart").append("svg")
      .attr("width", width + margin.left + margin.right)
      .attr("height", height + margin.top + margin.bottom)
    .append("g")
      .attr("transform", 
            "translate(" + margin.left + "," + margin.top + ")");
  
          d3.csv("/chart-arr", function(error, data) {
  
      data.forEach(function(d) {
          d.date = parseDate(d.date);
          d.value = +d.value;
      });
  
    x.domain(data.map(function(d) { return d.date; }));
    y.domain([0, d3.max(data, function(d) { return d.value; })]);
  
    svg.append("g")
        .attr("class", "x axis")
        .attr("transform", "translate(0," + height + ")")
        .call(xAxis)
      .selectAll("text")
        .style("text-anchor", "end")
        .attr("dx", "-.8em")
        .attr("dy", "-.55em")
        .attr("transform", "rotate(-90)" );
  
    svg.append("g")
        .attr("class", "y axis")
        .call(yAxis)
        .attr("width", "150")
      .append("text")
        .attr("transform", "rotate(-90)")
        .attr("y", 6)
        .attr("dy", ".91em")
        .attr("width", "150")
        .style("text-anchor", "end")
        .text("Value ($)");
  
    svg.selectAll("bar")
        .data(data)
      .enter().append("rect")
        .style("fill", "steelblue")
        .attr("x", function(d) { return x(d.date); })
        .attr("width", x.rangeBand())
        .attr("y", function(d) { return y(d.value); })
        .attr("height", function(d) { return height - y(d.value); });
  
  });
  
  &lt;/script&gt;
  </code></pre>
  
  <p>Right now the Y-axis is not wide enough to accommodate the text labels.  My question is, how can I make the Y-axis wider to accommodate longer text labels on the Y-axis?  </p>
  
  <p>I tried attr("width") and various other tweaks but nothing is working.  </p>
  
  <p>Any help is greatly appreciated!</p>
