เรื่องการดึงรูปของ กราฟออกมาแสดงครับผม .....คือผมใช้ระบบกราฟของ jpgraph.

<?php
require_once ('jpgraph/jpgraph.php');
require_once ('jpgraph/jpgraph_bar.php');

$datay[0]=50;
$datay[1]=550;
$datay[2]=550;
$datay[3]=550;
$graph = new Graph(500,350);
$graph->SetScale("textlin");

$bplot = new BarPlot($datay);


$fmtStr = "javascript:window.open('details.php?id=%d','_new','width=500,height=300');void(0)";

$n = count($datay);
$targ=array();
$alts=array();
for($i=0; $i < $n; ++$i) {
    $targ[$i] = sprintf($fmtStr,$i+1);
    $alts[$i] = 'val=%d'; 
}
$bplot->SetCSIMTargets($targ,$alts);
$graph->Add($bplot);
$graph->title->Set("day");
$graph->title->SetFont(FF_FONT2,FS_BOLD);
$graph->title->SetCSIMTarget(sprintf($fmtStr,-1),'Title for Bar'); 

$graph->StrokeCSIM();

?>

include('bar.php');
