JpGraph常用的几种图表

本文只是介绍了JpGraph生成常见的几种图表的方法，如果无法满足需求，可查看官方文档example中的例子。

柱状图1：

<?php
include ("jpgraph/jpgraph.php");
include ("jpgraph/jpgraph_bar.php");
 
$data = array(19,23,34,38,45,67,71,78,85,87,96,145);         //定义数组
$ydata = array("一","二","三","四","五","六","七","八","九","十","十一","十二");
$graph = new Graph(500,300);                                //创建新的Graph对象
$graph->SetScale("textlin");
 
$graph->SetShadow();                                         //设置阴影
$graph->img->SetMargin(40,30,40,50);                         //设置边距
$barplot = new BarPlot($data);                               //创建BarPlot对象
$barplot->SetFillColor('orange');                            //设置颜色
                                    
$graph->Add($barplot);                                       //将柱形图添加到图像中
$barplot->value->Show();                                      //设置显示数字
 
$graph->title->Set("CDN流量图");                             //设置标题和X-Y轴标题
$graph->title->SetColor("red");
$graph->title->SetMargin(10);
$graph->xaxis->title->Set("月份");
$graph->xaxis->title->SetMargin(5);
$graph->xaxis->SetTickLabels($ydata);
$graph->yaxis->title->Set("流 量(Mbits)");
 
$graph->title->SetFont(FF_SIMSUN,FS_BOLD);                                                      //设置字体
