There may be occasions where we don't want an entire server running to render a few charts. In this case, we can opt for a slightly simpler solution and render to specific image formats at the same time.

Getting ready

To set up and run PhantomJS, refer to the Getting ready section of the Rendering charts on the server side recipe given earlier in this chapter.

How to do it...

        "series": [{
            "name": "Bar #1",
            "data": [1, 2, 3, 4]
        }]
    }
  2. Change directories to Highcharts/exporting-server/phantomjs.

  3. Run the following command to generate a chart from options.json:
