title: How can I construct a jquery/flot bar chart, without the vertical axis lines?
body: <p>I am exploring flot, the jquery graphing library. </p>
  
  <p>I'd like to be able to create a bar chart. Seems like it was not really set up for this.  If I contort my data a little, I can get it to mostly do what I envision.  Using this code: </p>
  
  <pre><code>  var dataSet = [
      [ 15132, "Inez" ],
      [ 21441, "Rocky" ],
      [ 29141, "Jim" ],
      [ 18211, "Sophia" ],
      [ 17556, "Perry" ],
      [ 32251, "Jorge" ],
      [ 43560, "Madison" ],
      [ 20180, "Gil" ],
      [ 12180, "Fran" ],
      [ 31018, "Sheila" ],
      [ 45143, "Nial" ],
    ];
  
  
    function plotChart() {
      var d1, xaxisLabels = [], i=0;
  
      d1 = dataSet.map(function(elt){return {label: elt[1], data: [[i++, elt[0]]]};});
      i = 0;
      // example for xaxis option: {ticks: [[1,'One'], [2,'Two'], [3,'Three'], [4,'Four'], [5,'Five']]},
      xaxisLabels = dataSet.map(function(elt) { return [i++, elt[1]]; });
      $.plot($("#chart1"),
             d1,
             {
               legend: {
                 show: true,
                 container: $('#legend1'),
               },
               series: {
                     bars: {
                       show       : true,
                       align      : 'center',
                       //dataLabels : true,
                       barWidth : 0.4
                     }
               },
               xaxis: { ticks: xaxisLabels },
               yaxis: {
                     ticks: 10
               },
               grid: {
                     show: true,
                     backgroundColor: { colors: ["#fff", "#eee"] }
               }
             });
  }
  
  $(document).ready(plotChart);

  <p>This is what I get: </p>
  
  <p><img src="https://i.stack.imgur.com/nhe54.png" alt="enter image description here"></p>
  
  <p>That's pretty good.   But I'd like to remove the vertical axis lines. These might make sense in a line chart, but not in a bar chart. </p>
  
  <p>Anyone know how I can do that?  </p>
