php使用Jpgraph绘制复杂X

本文实例讲述了php使用jpgraph绘制复杂x-y坐标图的方法。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_line.php"); $data1 = array(19,23,34,38,怎么写读书笔记45,67,71,78,85,87,90,96); //第一条曲线的数组 $data2 = array(523,634,371,278,685,587,490,256,398,545,367,577); //第二条曲线的数组 $graph = new graph(400,300); //创建新的graph对象 $graph->tscale("textlin"); $graph->ty2scale("lin"); $graph->tshadow(); //设置图像的阴影样式 $graph->img->tmargin(40,50,20,70); //设置图像边距 $graph->title-&集体游戏室内gt;t("年度收支表"); //设置图像标题 $lineplot1=new lineplot($data1); //创建设置两条曲线对象 $lineplot2=new lineplot($data2); $graph->add($lineplot1); //将曲线放置到图像上 $graph->addy2($lineplot2); $graph->xaxis->title->t("月份"); //设置坐标轴名称 $graph->yaxis->title->t("兆美元"); $graph->y2axis->title->t("兆美元"); $graph->title->tfont(ff_simsun,fs_bold); //设符号名字大全置字体 $graph->yaxis->title->tfont(ff_simsun,fs_bold); $graph->y2axis->title->tfont(ff_simsun,fs_bold); $graph->xaxis->title->tfont(ff_simsun,fs_bold); $lineplot1->tcolor("red"); //设置颜色 $lineplot2->tcolor("blue"); $lineplot1->tlegend("cost amount"); //设置图我总也忘不了那句话例名称 $lineplot2->tlegend("revenue amount"); $graph->但使龙城飞将在不教胡马度阴山的意思legend->tlayout(legend_hor); //设置图例样式和位置 $graph->legend->pos(0.4,0.95,"center","bottom"); $graph->stroke(); //输出图像 ?>

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。
