  <p>This chart does not render but gives me an error message in the console of my Chrome browser: <code>Uncaught TypeError: Cannot read property 'plugins' of undefined</code>. The error points to a piece of code in the <em>jquery.flot.time.js</em> file: <code>$.plot.plugins.push({
          init: init,
          options: options,
          name: 'time',
          version: '1.0'
      });</code> </p>
  
  <p>"step2" passes OK, "step3" is never reached.
  Does anyone knows what to do? My jQuery is 3.1.1</p>
