title: Avoid to show tooltip in barspacing of sparkline bar chart
body: <p>I have created space between bar graphs. But I want to show tooltip only on bar not in blank space. </p>
  
  <pre><code>var values = [100.00,100.00,100.00,80.00,80.00,66.67];
  
  // Draw a sparkline for the #sparkline element
  $('#sparkline').sparkline(values, {
      type: "bar",
      // Map the offset in the list of values to a name to use in the tooltip
      tooltipFormat: '{{offset:offset}} {{value}}',
      barSpacing: '50px',
      tooltipValueLookups: {
          'offset': {
              0: 'Jul',
              1: 'Aug',
              2: 'Sep',
              3: 'Oct',
              4: 'Nov',
              5: 'Dev',
          }
      },
  })
  </code></pre>
