PHP / Re:podrian resolverme una duda de graficas
« en: 23 de Octubre de 2009, 22:37:35 pm »
ya encontre este codigo, pero solo me hace una sola barra y quiero saber si alguien me puede ayudar a poner varias barras o un grupo de barras, ojala me puedan ayudar, muchas graxias 
Código: [Seleccionar]
<?php // content="text/plain; charset=utf-8"
include_once ("jpgraph/jpgraph.php");
include_once ("jpgraph/jpgraph_bar.php");
// Some random data to plot
$datay=array(12,26,9,17,31,8,9);
// Create the graph.
$graph = new Graph(440,440,'auto');
$graph->SetScale("textlin");
// Create a bar pot
$bplot = new BarPlot($datay);
// Create targets for the image maps so that the details are o*****d in a separate window
$fmtStr = "javascript:window.open('barcsim_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';
// Note: The format placeholder val=%d will be replaced by the actual value in the ouput HTML by the
// library so that when the user hoovers the mouse over the bar the actual numerical value of the bar
// will be dísplayed
}
$bplot->SetCSIMTargets($targ,$alts);
// Add plot to graph
$graph->Add($bplot);
// Setup the title, also wih a CSIM area
$graph->title->Set("CSIM with popup windows");
$graph->title->SetFont(FF_FONT2,FS_BOLD);
// Assume we can give more details on the graph
$graph->title->SetCSIMTarget(sprintf($fmtStr,-1),'Title for Bar');
// Send back the HTML page which will call this script again to retrieve the image.
$graph->StrokeCSIM();
?>
