本文实例讲述了php使用Jpgraph绘制柱形图的方法。分享给大家供大家参考。具体实现方法如下：

<?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。
