   One way to do this is to use an invisible graphic as a clickable element that covers the chart area. That is, add the following 'graphic' option to your chart
   ```
   var chart_width = 1000
   var chart_height = 200
   
   function(params) {
     console.log('CLICK')
   }
   
   {graphic: {
     type: 'rect',
     shape: {
       x: 0,
       y: 0,
       height: chart_height,
       width: chart_width
     },
     onclick: onClick,
     invisible: true,
     z: 100
   }}
   ```
