新手初識jpgraph一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:
$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); //圖像高寬
$graph->SetScale(“textlin”);
$graph->xaxis->SetTickLabels( $datax);
$graph->xaxis->SetFont(FF_VERDANA,FS_NORMAL,10);
$graph->xaxis->SetLabelglegle(30);
$graph->yaxis->scale->SetAngle(30);
$graph->yaxis->scale->SetAngle(20);
$graph->xaxis->scale->SetGrace(20);
// Add a drop shadow
$graph->SetShadow();
// Adjust the margin a bit to make more room for titles 🎟 >img->SetMargin(40,30,20,40);
// Create a bar pot
$bplot = new BarPlot($datay);
// Adjust fill color
$bplot->SetFillor(''prange) ;
$bplot->value->Show();
$bplot->value->SetFont(FF_ARIAL,FS_BOLD,10);
$bplot->value->SetAngle(45); >SetFormat('%d');
$graph->Add($bplot);
// Setup the titles
$graph->title->Set(iconv(“UTF-8″, “gb2312″,”用戶消費報表圖」));
$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();
