title: How to pass data in jqPlot meter gauge?
body: <p>I' m using this <a href="http://www.jqplot.com/examples/meterGauge.php" rel="nofollow noreferrer">plugin</a></p>
  
  <p>There's a gauge on my page:</p>
  
  <pre><code>s1 = [50000];
  
     plot4 = $.jqplot('chart4',[s1],{
       seriesDefaults: {
         renderer: $.jqplot.MeterGaugeRenderer,
         rendererOptions: {
             label: 'Metric Tons per Year',
             labelPosition: 'bottom',
             labelHeightAdjust: -5,
             intervalOuterRadius: 85,
             ticks: [10000, 30000, 50000, 70000],
             intervals:[22000, 55000, 70000],
             intervalColors:['#66cc66', '#E7E658', '#cc6666']
         }
       }
   });
  </code></pre>
  
  <p>I want the next scenario: user enters a number in input, presses submit and arrow shows this value on gauge. So, I've made an input and added this code right above the gauge code:</p>
  
  <pre><code>$(".btn").click(function() {
    var data = $("#test").val();
    s1 = [data];
    console.log(s1);
    return s1;
  });
  </code></pre>
  
  <p>Console outputs value, but how to make the arrow show this value? Cannot find any method for this in the documentation.</p>
