PHP圖形映像的典型應用 –常用映像的應用（統計圖）

基於GD庫和JPgraph庫

說明：對於具體的Jpgraph類庫的用法，請參照官網的文檔:http://jpgraph.net/download/manuals/classref/index.html

對於下面涉及到的代碼，裡面的JPgraph類檔案可能路徑不一樣，我是按照我自己檔案存放的路徑引入的。你們可自行更改

1、使用直條圖統計月銷量額

<?php    /*        具體的Jpgraph類庫的用法，請參照官網的文檔:http://jpgraph.net/download/manuals/classref/index.html    */    /*****************************使用直條圖統計月銷量額**************************/    include("D:/PHP_Config/jpgraph-3.5.0b1/src/jpgraph.php");    include("D:/PHP_Config/jpgraph-3.5.0b1/src/jpgraph_bar.php"); //引用直條圖對象所在的檔案    $datay = array(160,180,203,289,405,488,489,408,299,166,187,105); //定義數組    $graph = new Graph(600,300,"auto"); //建立畫布 --要JPgraph庫的支援    $graph->SetScale("textlin");    $graph->yaxis->scale->SetGrace(20);    $graph->SetShadow();  //建立畫布陰影    //設定統計圖所在畫布的位置，左邊距40、右邊距30、上邊距30、下邊距40，單位為像素    $graph->img->SetMargin(40,30,30,40);        $bplot = new BarPlot($datay);  //建立一個矩形的對象    $bplot->SetFillColor('orange');   //設定直條圖的顏色    $bplot->value->Show();   //設定顯示數字    $bplot->value->SetFormat('%d');   //在直條圖中顯示格式化的圖書銷量        $graph->Add($bplot);  //將矩形圖添加到映像中    $graph->SetMarginColor("lightblue");  //設定畫布背景色為淺藍色    $graph->title->Set("<<PHP for Introduction 2009>> Annual sales statistics");  //建立標題    //設定X軸座標文字    $a=array("1 月","2 月","3 月","4 月","5 月","6 月","7 月","8 月","9 月","10 月","11 月","12 月");    $graph->xaxis->SetTickLabels($a);   //設定X軸    $graph->title->SetFont(FF_SIMSUN);  //設定標題字型    $graph->xaxis->SetFont(FF_SIMSUN);  //設定X軸的字型    $graph->Stroke();  //輸出映像?>

<?php    /***************************使用折線圖統計月銷量額*******************************/    include("D:/PHP_Config/jpgraph-3.5.0b1/src/jpgraph.php");    include("D:/PHP_Config/jpgraph-3.5.0b1/src/jpgraph_line.php"); //引用折線圖LinePlot類檔案    //定義數組    $datay = array(8320,9360,14956,17028,13060,15376,25428,16216,28548,18632,22724,28460);     $graph = new Graph(600,300,"auto");    //設定統計圖所在畫布的位置，左邊距50，右邊距40，上邊距30，下邊距40，單位為像素    $graph->img->SetMargin(50,40,30,40);    $graph->img->SetAntiAliasing();  //設定折線的平滑狀態    $graph->SetScale("textlin");  //設定刻度樣式    $graph->SetShadow();   //建立畫布陰影    $graph->title->Set("<<PHP for Introduction 2009>> Annual sales statistics");  //設定標題    $graph->title->SetFont(FF_SIMSUN,FS_BOLD);  //設定標題字型    $graph->SetMarginColor("lightblue");  //設定畫布背景色為淡藍色    $graph->yaxis->title->SetFont(FF_SIMSUN,FS_BOLD);   //設定Y軸標題的字型    $graph->xaxis->SetPos("min");   //    $graph->yaxis->HideZeroLabel();    $graph->ygrid->SetFill(true,'#EFEFEF@0.5','#BBCCFF@0.5');    //X軸    $a=array("1 月","2 月","3 月","4 月","5 月","6 月","7 月","8 月","9 月","10 月","11 月","12 月");    $graph->xaxis->SetTickLabels($a);  //設定X軸    $graph->xaxis->SetFont(FF_SIMSUN);  //設定X坐軸的字型    $graph->yscale->SetGrace(20);          $p1 = new LinePlot($datay);  //建立折線圖對象    $p1->mark->SetType(MARK_FILLEDCIRCLE);  //設定資料座標點為圓形標記    $p1->mark->SetFillColor("red");   //設定填充顏色    $p1->mark->SetWidth(4);  //設定圓形標記的直徑為4像素    $p1->SetColor("blue");  //設定折線顏色為藍色    $p1->SetCenter();  //在X軸的各座標點中心位置繪製折線        $graph->Add($p1);  //在統計圖上繪製折線    $graph->Stroke();  //輸出映像?>

<?php    /*************************使用3D餅圖進行統計***************************/    include("D:/PHP_Config/jpgraph-3.5.0b1/src/jpgraph.php");    include("D:/PHP_Config/jpgraph-3.5.0b1/src/jpgraph_pie.php");    //引用 3D 餅形圖 PiePlot3D對象所在的類檔案    include("D:/PHP_Config/jpgraph-3.5.0b1/src/jpgraph_pie3d.php");    //定義數組    $data = array(266036,295621,335851,254256,254254,685425);    $graph = new PieGraph(540,260,'auto');  //建立畫布    $graph->SetShadow();  //設定畫布陰影        //建立標題    $graph->title->Set("<<PHP for Introduction 2009>> Annual sales statistics -3DPie");    $graph->title->SetFont(FF_SIMSUN,FS_BOLD);  //設定標題字型    $graph->legend->SetFont(FF_SIMSUN,FS_NORMAL);  //設定圖例字型        $p1 = new PiePlot3D($data);  //建立3D餅圖對象    $p1->SetLegends(array("IT","Appliance","Daily","Clothing","Health","Food"));    $targ = array("D:/PHP_Config/jpgraph-3.5.0b1/src/Examples/pie3d_csimex1.php?v=1","D:/PHP_Config/jpgraph-3.5.0b1/src/Examples/pie3d_csimex1.php?v=2","D:/PHP_Config/jpgraph-3.5.0b1/src/Examples/pie3d_csimex1.php?v=3","D:/PHP_Config/jpgraph-3.5.0b1/src/Examples/pie3d_csimex1.php?v=4","D:/PHP_Config/jpgraph-3.5.0b1/src/Examples/pie3d_csimex1.php?v=5","D:/PHP_Config/jpgraph-3.5.0b1/src/Examples/pie3d_csimex1.php?v=6");    $alts = array("val=%d","val=%d","val=%d","val=%d","val=%d","val=%d");    $p1->SetCSIMTargets($targ,$alts);    $p1->SetCenter(0.4,0.5);  //設定餅圖所在畫布的位置        $graph->Add($p1);  //將3D餅形圖添加到映像中    $graph->StrokeCSIM();  //將映像輸出到遊覽器?>
