本文实例讲述了php图形jpgraph操作。分享给大家供大家参考，具体如下：

SetScale("textlin");//设置图形的边距$graph->img->SetMargin(40,180,40,40);//设置图形的背景图片，填充方式有：BGIMG_FILLPLOT, BGIMG_FILLFRAME, BGIMG_COPY$graph->SetBackgroundImage("abc.jpg",BGIMG_FILLPLOT);$graph->img->SetAngle(45); //设置图形在图像中的角度//设置背景图片的对比度，must be between -1 <= x <= 1, (0,0)=original image$graph->AdjBackgroundImage(0,0);//设置投影；//$graph->SetShadow();//设置标题$graph->title->Set("test image");//设置标题字体样式$graph->title->SetFont(FF_FONT1,FS_BOLD);//设置标题的边距$graph->title->SetMargin(3);//设置图列的位置$graph->legend->Pos(0.05,0.5,"right","center");//设置图列的投影，颜色$graph->legend->SetShadow('[email protected]');$graph->legend->SetFillColor('[email protected]');//设置x轴的标记$graph->xaxis->SetTickLabels($label_x);//设置X轴的显示值的角度;$graph->xaxis->SetLabelAngle(30);//设置x轴标题和字体颜色$graph->xaxis->title->Set('Year 2006');$graph->xaxis->title->SetFont(FF_FONT1,FS_BOLD);$graph->xaxis->title->SetColor('white');//设置x轴的字体和颜色$graph->xaxis->SetFont(FF_FONT1,FS_BOLD);$graph->xaxis->SetColor('yellow');//设置y轴的字体和颜色$graph->yaxis->SetFont(FF_FONT1,FS_BOLD);$graph->yaxis->SetColor('yellow');//设置是否显示格子。默认为显示；//$graph->ygrid->Show(false);//设置格子的颜色和粗细。值越小，格子越粗。$graph->ygrid->SetColor('[email protected]');//设置y轴更优美一些$graph->yaxis->scale->SetGrace(20);//设置图列的数据$bplot1 = new BarPlot($datay1);$bplot2 = new BarPlot($datay2);//设置图列的填充颜色$bplot1->SetFillColor('[email protected]');$bplot2->SetFillColor('[email protected]');//设置值的格式$bplot1->value->SetFormat('%d');//设置图列标签$bplot1->SetLegend('Label 1');$bplot2->SetLegend('Label 2');//设置图列在图中的阴影$bplot1->SetShadow('[email protected]');$bplot2->SetShadow('[email protected]');//生成图列$gbarplot = new GroupBarPlot(array($bplot1,$bplot2));$gbarplot->SetWidth(0.9);$graph->Add($gbarplot);//生成图形$graph->Stroke();//上面所说的时在生成柱形图，当生成线性图时用下面的方法$p1 = new LinePlot($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")$lineplot->SetStyle("dashed");//设置线的样式$graph->yaxis->scale->SetGrace(20); //设置y轴更优美一些?>

2.柱形图和饼状图举例

if($tag == 1){$graph = new Graph(600,400,"auto");$graph->SetScale("textlin");$graph->setMarginColor('lightblue');$graph->SetShadow();$graph->setMargin(30,100,30,60);//设置标题;$graph->title->set("文章分类汇总");$graph->title->SetMargin(3);$graph->title->setfont(FF_SIMSUN,FS_BOLD);$graph->title->setcolor('[email protected]');$graph->yaxis->title->SetFont(FF_SIMSUN,FS_BOLD);$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);$bplot->SetLegend("文章数");$graph->Add($bplot);$graph->Stroke();}else{$graph1 = new PieGraph(600,400,"auto");$graph1->SetScale("textlin");$graph1->SetShadow();$graph1->title->setFont(FF_SIMSUN,FS_BOLD);$graph1->title->set("用户文章饼形图");$graph1->setMargin(30,100,30,60);$p1 = new pieplot3d($article_num);$p1->setAngle(80);$p1->setsize(0.5);$p1->setShadow();$p1->ExplodeSlice(2);$p1->SetCenter(0.4);$graph1->legend->SetFont(FF_SIMSUN,FS_NORMAL);$graph1->legend->setshadow();$p1->SetLegends($name);$graph1->Add($p1);$graph1->Stroke();}//生成本地图片$graph->Stroke("路径/文件名.png");
