title: nvd3: remove y-axis tick labels from discrete bar chart
body: <p>I am trying to remove y-axis tick labels from a discrete bar chart in nvd3.</p>
  
  <p>I already looked into the nvd3 source, but can't find an obvious function I could change. Can anyone point me to the solution?</p>
  
  <p>Update: Code</p>
  
  <pre><code>function Transform(value1, value2, chart_name,value3) {
  value3 = typeof value3 !== 'undefined' ? value3 : 'no_header';
  var chart = nv.models.discreteBarChart()
      .x(function (d) {
      return d.label;
  })
  
      .y(function (d) {
      return d.value;
  })
  
      .staggerLabels(true)
      .tooltips(false)
      .showValues(true);
  
  var a = [];
  var f = [{
      values: []
  }];
  d3.csv("../../csv/master.csv").get(function (error, rows) {
  
   if (error){
      console.log(error);
      loadError("Uh Oh. This  data set is missing... Try going &lt;a href='/'&gt;back to the start&lt;/a&gt;");
      return;
      }
  
      for (var i = 0; i &lt; rows.length; i++) {
          a.push(rows[i]);
      }
      console.log(a[0].agency);
      for (var key = 0; key &lt; a.length; key++) {
          var b = a[key];
          for (var c in b) {
              if (c != "agency" &amp;&amp; c != "division" &amp;&amp; c != "pod") {
                  var d = b[c];
                  a[key][c] = +d;
              }
          }
          console.log(a[0].changes);
          }
    try {
      var e = $.grep(a, function (v) {
        return v.division == {{division|safe}};
          });
      var k = $.grep(e, function(v) {
        return v.agency == {{agency|safe}};
        })[0];
      console.log(k.division);
        }
    catch (TypeError) { loadError("Uh Oh. We could not find this combination\
        of Agency &amp; Division. Try going back to the &lt;a href='/pitchview'&gt;selection menu&lt;/a&gt;");
      return;
    }
    if (k.agency){
      for (var g in k) {
          if (g == value1 || g == value2 || g == value3) {
              var h = {
                  "label": g,
                      "value": k[g]
              };
              f[0].values.push(h);
          }
      }
  
  
      d3.select('#' + chart_name + ' svg')
          .datum(f)
          .transition().duration(500)
          .call(chart)
      nv.utils.windowResize(chart.update);
