   jpgraph是php中一個非常非常強大的第三方報表工具,據說能完成一切你想要的圖形…

  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

  $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();

  ?>
