小編給大家分享一下php圖形jpgraph操作的示例分析,相信大部分人都還不怎么了解,因此分享這篇文章給大家參考一下,希望大家閱讀完這篇文章后大有收獲,下面讓我們一起去了解一下吧!
具體如下:
<?php include ("src/jpgraph.php"); include("src/jpgraph_bar.php"); include ("src/jpgraph_line.php"); //設置顯示的數據數組; //調用類庫 //設置圖像的大小 $graph = new Graph(400,200,"auto"); $graph->SetScale("textlin"); //設置圖形的邊距 $graph->img->SetMargin(40,180,40,40); //設置圖形的背景圖片,填充方式有:BGIMG_FILLPLOT, BGIMG_FILLFRAME, BGIMG_COPY $graph->SetBackgroundImage("abc.jpg",BGIMG_FILLPLOT); $graph->img->SetAngle(45); //設置圖形在圖像中的角度 //設置背景圖片的對比度,must be between -1 <= x <= 1, (0,0)=original image $graph->AdjBackgroundImage(0,0); //設置投影; //$graph->SetShadow(); //設置標題 $graph->title->Set("test image"); //設置標題字體樣式 $graph->title->SetFont(FF_FONT1,FS_BOLD); //設置標題的邊距 $graph->title->SetMargin(3); //設置圖列的位置 $graph->legend->Pos(0.05,0.5,"right","center"); //設置圖列的投影,顏色 $graph->legend->SetShadow('darkgray@0.1'); $graph->legend->SetFillColor('lightblue@0.3'); //設置x軸的標記 $graph->xaxis->SetTickLabels($label_x); //設置X軸的顯示值的角度; $graph->xaxis->SetLabelAngle(30); //設置x軸標題和字體顏色 $graph->xaxis->title->Set('Year 2006'); $graph->xaxis->title->SetFont(FF_FONT1,FS_BOLD); $graph->xaxis->title->SetColor('white'); //設置x軸的字體和顏色 $graph->xaxis->SetFont(FF_FONT1,FS_BOLD); $graph->xaxis->SetColor('yellow'); //設置y軸的字體和顏色 $graph->yaxis->SetFont(FF_FONT1,FS_BOLD); $graph->yaxis->SetColor('yellow'); //設置是否顯示格子。默認為顯示; //$graph->ygrid->Show(false); //設置格子的顏色和粗細。值越小,格子越粗。 $graph->ygrid->SetColor('yellow@0.5'); //設置y軸更優美一些 $graph->yaxis->scale->SetGrace(20); //設置圖列的數據 $bplot1 = new BarPlot($datay1); $bplot2 = new BarPlot($datay2); //設置圖列的填充顏色 $bplot1->SetFillColor('orange@0.4'); $bplot2->SetFillColor('brown@0.4'); //設置值的格式 $bplot1->value->SetFormat('%d'); //設置圖列標簽 $bplot1->SetLegend('Label 1'); $bplot2->SetLegend('Label 2'); //設置圖列在圖中的陰影 $bplot1->SetShadow('black@0.4'); $bplot2->SetShadow('black@0.4'); //生成圖列 $gbarplot = new GroupBarPlot(array($bplot1,$bplot2)); $gbarplot->SetWidth(0.9); $graph->Add($gbarplot); //生成圖形 $graph->Stroke(); //上面所說的時在生成柱形圖,當生成線性圖時用下面的方法 $p1 = new LinePlot($datay); $p1->mark->SetType(MARK_FILLEDCIRCLE); $p1->mark->SetFillColor("red"); $p1->mark->SetWidth(4); $p1->SetColor("blue"); $p1->SetCenter(); $p1->SetLegend("Triumph Tiger -98"); $graph->Add($p1); $p2 = new LinePlot($data2y); $p2->mark->SetType(MARK_STAR); $p2->mark->SetFillColor("red"); $p2->mark->SetWidth(4); $p2->SetColor("red"); $p2->SetCenter(); $p2->SetLegend("New tiger -99"); $graph->Add($p2); // Style can also be specified as SetStyle([1|2|3|4]) or // SetStyle("solid"|"dotted"|"dashed"|"lobgdashed") $lineplot->SetStyle("dashed");//設置線的樣式 $graph->yaxis->scale->SetGrace(20); //設置y軸更優美一些 ?>
2.柱形圖和餅狀圖舉例
if($tag == 1) { $graph = new Graph(600,400,"auto"); $graph->SetScale("textlin"); $graph->setMarginColor('lightblue'); $graph->SetShadow(); $graph->setMargin(30,100,30,60); //設置標題; $graph->title->set("文章分類匯總"); $graph->title->SetMargin(3); $graph->title->setfont(FF_SIMSUN,FS_BOLD); $graph->title->setcolor('black@0.5'); $graph->yaxis->title->SetFont(FF_SIMSUN,FS_BOLD); $graph->xaxis->title->SetFont(FF_SIMSUN,FS_BOLD); $graph->xaxis->SetFont(FF_SIMSUN,FS_NORMAL); $graph->xaxis->SetColor('darkblue','black'); $graph->xaxis->SetTickLabels($name); $graph->xaxis->SetLabelAngle(30); $bplot = new BarPlot($article_num); $bplot->SetFillColor("orange"); $bplot->value->SetFormat('%d'); $bplot->SetShadow('darkgray'); $bplot->value->show(); $graph->legend->SetFont(FF_SIMSUN,FS_BOLD); $bplot->SetLegend("文章數"); $graph->Add($bplot); $graph->Stroke(); } else { $graph2 = new PieGraph(600,400,"auto"); $graph2->SetScale("textlin"); $graph2->SetShadow(); $graph2->title->setFont(FF_SIMSUN,FS_BOLD); $graph2->title->set("用戶文章餅形圖"); $graph2->setMargin(30,100,30,60); $p1 = new pieplot3d($article_num); $p1->setAngle(80); $p1->setsize(0.5); $p1->setShadow(); $p1->ExplodeSlice(2); $p1->SetCenter(0.4); $graph2->legend->SetFont(FF_SIMSUN,FS_NORMAL); $graph2->legend->setshadow(); $p1->SetLegends($name); $graph2->Add($p1); $graph2->Stroke(); } //生成本地圖片 $graph->Stroke("路徑/文件名.png");
