title: Chart.js Bar Chart: How to remove space between the bars in v2.3?
body: <p>I'm trying to remove the space between my bar chart bars, but even though I see this solution many places it doesn't work for me.  It's also not mentioned in the Chart.js docs so that is odd.  Can someone tell me how to specify it?</p>
  
  <pre><code>var options = {
      barValueSpacing : 1,        // doesn't work; find another way
      barDatasetSpacing : 1,      // doesn't work; find another way
  
      legend: {
          display: false          // Hides annoying dataset label
      },
      tooltips: {
          callbacks: {
              label: function(tooltipItem) {
                  return tooltipItem.yLabel;
              }
          }
      }
  };
  
  var ctx = document.getElementById("canvasX").getContext("2d");          
  var myBarChart = new Chart(ctx, {
      type: 'bar',
      data: data,
      options: options
  });
  </code></pre>
