Generating pngs of charts on cron job

[jpawl1982]

Hi, I have been looking through CanvasJS and I really like how it looks and functions and would serve most of my needs. However, besides generating charts and graphs to the end user through the website, I also have a cron job written in PHP that crunches database input every few hours, and from that I would like to generate static pngs of charts (mostly line graphs). I’m using a run-of-the-mill jquery website and from how I see it, I can’t think of a way that this would be possible. Am I missing something simple / obvious that will allow me to do it, or is canvasjs really not suited for this?

@jpawl1982,

You can save the chart as image on the server with the help of headless browser like PhantomJS.

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 setup instruction.
