Example of a jpgraph column chart for PHP reports

Jpgraph is a very powerful Third-party reporting tool in PHP and is said to be able to do all the graphics you want ...

Novice first know Jpgraph will encounter a variety of problems, such as garbled something, this case is jpgraph3.0.7 production, also through my many experiments, solve garbled problem

$datay =array (); Ordinate data

$datax =array (); Horizontal coordinate data

foreach ($usernums as $key => $value) {

$datay [] = $value;

$datax [] = $userids [$key];

}

Require_once (' jpgraph-3.0.7/jpgraph/jpgraph.php ');

Require_once (' jpgraph-3.0.7/jpgraph/jpgraph_bar.php ');

Create the graph. These two calls are always required

$graph = new Graph (800,600); High image width

$graph->setscale ("Textlin");

$graph->xaxis->setticklabels ($datax);

$graph->xaxis->setfont (ff_verdana,fs_normal,10);

$graph->xaxis->setlabelangle (30);

$graph->yaxis->scale->setgrace (20);

$graph->xaxis->scale->setgrace (20);

Add a drop Shadow

$graph->setshadow ();

Adjust the "margin a bit to" room for titles

$graph->img->setmargin (40,30,20,40);

Create a bar pot

$bplot = new Barplot ($datay);

Adjust Fill Color

$bplot->setfillcolor (' orange ');

$bplot->value->show ();

$bplot->value->setfont (ff_arial,fs_bold,10);

$bplot->value->setangle (45);

$bplot->value->setformat ('%d ');

$graph->add ($bplot);

Setup the titles

$graph->title->set (Iconv ("Utf-8″," Gb2312″, "User Consumption Report Chart"));

$graph->xaxis->title->set (Iconv ("Utf-8″," Gb2312″, "user name"));

$graph->yaxis->title->set (Iconv ("Utf-8″," Gb2312″, "Number of User Orders"));

$graph->xaxis->title->setfont (Ff_simsun,fs_bold);

$graph->yaxis->title->setfont (Ff_simsun,fs_bold);

$graph->title->setfont (Ff_simsun,fs_bold);

Display the graph

$graph->stroke ();

?>
