I'm using jpgraph or GD for charts making, and the picture is correctly made
in cache or in directory and there is no error log but when I use it in php
page ( <IMG src=graph.php >, I have a no-pict icon instead of my graph.
For information the graph.php script :
<%
$sitename="scafoot"; include("/var/www/jpgraph/src/jpgraph.php");
include("/var/www/jpgraph/src/jpgraph_line.php");
require("./connect.php");
$graph = new Graph(400,250,"auto"); $graph->SetScale("textlin");
$graph->img->SetMargin(40,20,20,40);
$sql="select idstat,week(date) as week,count(*) as count from pages where
host like '%$sitename%' group by week"; condb($sql,$result);
$ydata=array(0); $xdata=array(0);
while($row=mysql_fetch_array($result))
{
array_push($xdata,$row[week])
array_push($ydata,$row[count])
}
$graph->yaxis->title->Set("freq");
$graph->xaxis->title->Set("semaine");
$graph->xaxis->SetTrickLabels($xdata);
$lineplot=new LinePlot($ydata);
$lineplot->SetColor("blue");
$graph->Add($lineplot);
Header("Content-type: image/png");
$graph->Stroke();
