title: How to Set Color of Column Graph On Click in amCharts?
body: <p>I am trying to change color of selected column in a column graph (built using amCharts).</p>
  
  <p>I have an event listener in place like this:</p>
  
  <pre><code>function handleClick(event) {
  
          event.item.graph.backgroundColor = "#3C3C3C"; // NOT WORKING
          display_value = event.item.graph.valueField + ": " + event.item.category + ": "  + event.item.values.value;
          console.log(display_value);
  
  }
  chart.addListener('clickGraphItem', handleClick);
  </code></pre>
  
  <p>This didn't work and I couldn't find any related example. I saw an example for Maps, but chart objects work differently.</p>
  
  <p>Please siggest</p>
