Question

My PHP web-site generates (among other things) a pie-chart which is built with Google Chart API. I would like to give the user an option to tweet a picture with the pie chart. These are the steps I thought I should take:
1. Taking a snapshot of the div I’m displaying the pie chart in
2. U/L it to a picture sharing service.
3. twitting that link through twitter API

How can I achieve step (1)?
Would you maybe recommend a different method to implement the task I’m after?

Answer 1

With FGC:

<?php
$image = file_get_contents('http://chart.googleapis.com/chart?chs=320x200&cht=bvs&chd=t:30,-60,50,140,80,-90&chds=-80,140&chxt=y');
file_put_contents('temp.png',$image);
?>
