<?php include ( "src/jpgraph.php" ); include ( "src/jpgraph_bar.php" ); $data = array (19,23,34,38,45,67,71,78,85,87,90,96); //定义数组 $graph = new Graph(400,300); //创建新的Graph对象 $graph ->SetScale( "textlin" ); $graph ->SetShadow(); //设置阴影 $graph ->img->SetMargin(40,30,20,40); //设置边距 $barplot = new BarPlot( $data ); //创建BarPlot对象 $barplot ->SetFillColor( 'blue' ); //设置颜色 $barplot ->value->Show(); //设置显示数字 $graph ->Add( $barplot ); //将柱形图添加到图像中 $graph ->title->Set( "年度收支表" ); //设置标题和X-Y轴标题 $graph ->xaxis->title->Set( "月份" ); $graph ->yaxis->title->Set( "总金额(兆美元)" ); $graph ->title->SetFont(FF_SIMSUN,FS_BOLD); //设置字体 $graph ->yaxis->title->SetFont(FF_SIMSUN,FS_BOLD); $graph ->xaxis->title->SetFont(FF_SIMSUN,FS_BOLD); $graph ->Stroke(); ?> |
运行效果如下图所示:
希望本文所述对大家的php程序设计有所帮助。
