How To Auto Create Pdf Using Highchart Graphs

I am using yii framework 1.14 with php on centos 5. I have designed a view that contains 4 graphs created using highcharts. i want to export this page to pdf from my controller/act

Solution 1:

I have installed phantomjs in my controller, created an array and encoded it with json with output to file. Then used phantomjs to convert it to image. See the code below.

I am using Yii and have highcharts located in the extensions folder which contains everything I need. I had to download and place batik in that directory.

$json = json_encode(array(
                        "chart"=>array(
                            "type"=>'column',
                            "width"=>1000,
                            "height"=>350
                            ),
                        "title"=>array(
                                "text"=>$title[$i]
                                ),                          
                        "xAxis"=>array(
                            "categories"=>$cat,                         
                            "labels"=>array(
                                "rotation"=>$rotation,
                                "align"=>'left',
                                "style"=>array(
                                    "fontSize"=>'8px',
                                    "fontFamily"=>'Verdana, sans-serif',
                                    "width"=>"75px"
                                )
                            )
                        ),
                        "yAxis"=>array(
                            "min"=>0,
                            "max"=>100,
                            "title"=>array(
                                "text"=>'% COMPLETE'
                            ),
                            "tickInterval"=>10
                        ),

                            //"floating"=> true
