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 
 
$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); 
 
$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(); 
 
?>
