新手初識jpgraph肯定會遇到各種各樣的問題,比如亂碼什麼的,本案例是jpgraph3.0.7製作,也經過本人的多次實驗，解決亂碼問題
複製代碼 代碼如下:<?php
$datay=array(); //縱座標資料
$datax=array(); //橫座標資料
foreach ($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); //映像高寬
$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″,”使用者消費報表圖”));
$graph->xaxis->title->Set(iconv(“UTF-8″, “gb2312″,”使用者姓名”));
$graph->yaxis->title->Set(iconv(“UTF-8″, “gb2312″,”使用者訂單數量”));
$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();
?>
