jpgraph是php中一个非常非常强大的第三方报表工具,据说能完成一切你想要的图形…新手初识jpgraph肯定会遇到各种各样的问题,比如乱码什么的,本案例是jpgraph3.0.7制作,也经过本人的多次实验,解决乱码问题.

php报表 jpgraph柱状图实例代码如下:

<?php$ 
	datay=array();      //纵坐标数据 
	$datax=array();     //横坐标数据 
	foreach ($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);    //图像高宽 
	$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 make more 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);//开源代码phprm.com 
	$bplot->value->SetAngle(45); 
	$bplot->value->SetFormat('%d'); 
	$graph->Add($bplot);// Setup the titles 
	$graph->title->Set(iconv("UTF-8″, "gb2312″,"用户消费报表图")); 
	$graph->xaxis->title->Set(iconv("UTF-8″, "gb2312″,"用户姓名")); 
	$graph->yaxis->title->Set(iconv("UTF-8″, "gb2312″,"用户订单数量")); 
	$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();
