I have been playing with pChart library and have been having issues getting it to work with both IE6 and Safari. It appears to work fine with IE7 and above and Firefox, but I would really like to get it to work with IE6 and Safari (iPhone browser).

 

I am not getting any errors when it renders the chart, but am getting a blank image. Does anyone have any experience with this utility?

Thise sample is designed to pass a few arrays via session variables to the litmChart.php page (pChart rendering processes). You will need to have the pChart classes in order for this to work (notice the include path), and the images will not show up, but everything else should be good.

Here is the main page:

<?php
       ob_start();
        include ('config.inc');
        session_start();
        header("Cache-control: private"); // IE 6 Fix.
        $dodebug=0;
        $hosturl=(substr($_SERVER['HTTP_HOST'],0,9)=='localhost')?"http://".$_SERVER['HTTP_HOST']:$_SESSION['http'].$_SERVER['HTTP_HOST']."/itemCost";
        echo $hosturl."<br>";
        $valid=1;
        /*
        if(!isset($_SESSION['firstload'])){
            echo '<meta http-equiv="refresh" content="2">';
            $_SESSION['firstload']=true;
            $valid=99;
        }
        else{
        */
        if($valid==1){
            $litm='Part Number';
            $aitm='Part Description';
            $branch='PA';
            // build working arrays
            $arr = array(736000,248400,1628400,55200,0,0,0,0,0,0,0,0);
            $arr1 = array(386400,156400,303600,165600,193200,616400,414000,257600,276000,349600,101200,82800);
            $arr2 = array(358800,220800,303600,174800,828000,119600, 92000,542800,717600,303600,257600, 478400);
            //for($i=1;$i<=12;$i++){$arr2[$i]=0;}
            $year=2009; 
            $year1=2008;
