导读:这篇文章主要介绍了php图形jpgraph操作,结合具体实例形式分析了php基于jpgraph图形库实现图形绘制的相关操作技巧,需要的朋友可以参考下
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('darkgray@0.1');
$graph->legend->SetFillColor('lightblue@0.3');
//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('yellow@0.5');
//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('orange@0.4');
$bplot2->SetFillColor('brown@0.4');
//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('black@0.4');
$bplot2->SetShadow('black@0.4');
//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 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('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("文章数"); $graph->Add($bplot); $graph->Stroke(); } else { $graph1 = new PieGraph(600,"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(30,60); $p1 = new pieplot3d($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");更多关于PHP相关内容感兴趣的读者可查看本站专题:《》、《》、《》、《》、《》、《》、《》及《》 希望本文所述对大家PHP程序设计有所帮助。 (编辑:甘南站长网) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
