Export charts as PNG on server

    I’m currently trying out Canvasjs on Centos O/S. For our solution we are looking at generating a number charts, saving them as png and and then building a report in HTML, then creating a PDF report from the HTML file (URL).

    My question is:
    How can I export the rendered charts as PNG on the server, without intervention e.g. headless in the background from a PHP script?

    Thanks in advance




    In order to render chart on the server side you would require a headless browser like PhantomJS. Here is an article which might help.
    Please take a look at this sample PhantomJS project, that captures the chart image from web page and saves it to a particular location. Please refer to instructions.txt file for clear understanding.
