主要分为三步：
- * 读取用于生成图表数据（数据库、文件）
- * 设计图表样式（圆角、底色等）
- * 制作标签、题目、图例并生成图表
下面看一个简单的柱状图表：
代码如下：
<?php
// Standard inclusions
include("pChart/pData.class");
include("pChart/pChart.class");
// Dataset definition
$DataSet = new pData;
//图表数据
$DataSet->AddPoint(array(1,4,-3,2,-3,3,2,1,0,7,4),"Serie1");
$DataSet->AddPoint(array(3,3,-4,1,-2,2,1,0,-1,6,3),"Serie2");
$DataSet->AddPoint(array(4,1,2,-1,-4,-2,3,2,1,2,2),"Serie3");
$DataSet->AddAllSeries();
$DataSet->SetAbsciseLabelSerie();
//数据图例
$DataSet->SetSerieName("Microsoft","Serie1");
$DataSet->SetSerieName("IBM","Serie2");
$DataSet->SetSerieName("Google","Serie3");
// Initialise the graph
$Test = new pChart(700,230);
//设置图表尺寸、样式
$Test->setFontProperties("Fonts/tahoma.ttf",8);
$Test->setGraphArea(50,30,680,200);
$Test->drawFilledRoundedRectangle(7,7,693,223,5,240,240,240);
$Test->drawRoundedRectangle(5,5,695,225,5,230,230,230);
$Test->drawGraphArea(255,255,255,TRUE);
$Test->drawScale($DataSet->GetData(),$DataSet->GetDataDescription(),SCALE_NORMAL,150,150,150,TRUE,0,2,TRUE);
$Test->drawGrid(4,TRUE,230,230,230,50);
// Draw the 0 line
$Test->setFontProperties("Fonts/MankSans.ttf",6);
$Test->drawTreshold(0,143,55,72,TRUE,TRUE);
// Draw the bar graph
//柱状图要使用drawBarGraph()
$Test->drawBarGraph($DataSet->GetData(),$DataSet->GetDataDescription(),TRUE,80);
// Finish the graph
//制作图例、标题、字体等属性
$Test->setFontProperties("Fonts/MankSans.ttf",10);
$Test->drawLegend(596,150,$DataSet->GetDataDescription(),255,255,255);
$Test->setFontProperties("Fonts/MankSans.ttf",10);
$Test->drawTitle(50,22,"Example",50,50,50,585);
//生成图表
$imageFile = "example12.png";
$Test->Render($imageFile);
echo '<img src="'.$imageFile.'">';
?>这个是雷达效果的：
代码：
<?php
// Standard inclusions
include("pChart/pData.class");
include("pChart/pChart.class");
// Dataset definition
$DataSet = new pData;
$DataSet->AddPoint(array("Memory","Disk","Network","Slots","CPU"),"Label");
$DataSet->AddPoint(array(6,4,7,4,5),"Serie1");
$DataSet->AddPoint(array(2,3,5,2,4),"Serie2");
$DataSet->AddSerie("Serie1");
$DataSet->AddSerie("Serie2");
$DataSet->SetAbsciseLabelSerie("Label");
$DataSet->SetSerieName("Reference","Serie1");
$DataSet->SetSerieName("Tested computer","Serie2");
// Initialise the graph
$Test = new pChart(400,400);
$Test->setFontProperties("Fonts/tahoma.ttf",8);
$Test->drawFilledRoundedRectangle(7,7,393,393,5,240,240,240);
$Test->drawRoundedRectangle(5,5,395,395,5,230,230,230);
$Test->setGraphArea(30,30,370,370);
$Test->drawFilledRoundedRectangle(30,30,370,370,5,255,255,255);
$Test->drawRoundedRectangle(30,30,370,370,5,220,220,220);
// Draw the radar graph
//要使用drawRadarAxis()生成雷达效果
$Test->drawRadarAxis($DataSet->GetData(),$DataSet->GetDataDescription(),TRUE,20,120,120,120,230,230,230);
$Test->drawFilledRadar($DataSet->GetData(),$DataSet->GetDataDescription(),50,20);
// Finish the graph
$Test->drawLegend(15,15,$DataSet->GetDataDescription(),255,255,255);
$Test->setFontProperties("Fonts/tahoma.ttf",10);
$Test->drawTitle(0,22,"Example",50,50,50,400);
$imageFile = "example8.png";
$Test->Render($imageFile);
echo '<img src="'.$imageFile.'">';
?>再看几个其他的效果
1，饼图：
2, 双座标曲线图：
3, 层叠柱状图：
4, 多图表：
图表的种类已经相当丰富了，具体图表设置请参考

当然可以，用php读取数据(从数据库或者文本文件中读取)，包括图片文件名，然后生成html的table，里面就可以加入<img>了。

你可以学习下
JpGraph简介
以前用PHP作图时必须要掌握复杂抽象的画图函数，或者借助一些网上下载的花柱形图、饼形图的类来实现。没有一个统一的chart类来实现图表的快速开发。
现在我们有了一个新的选择：JpGraph。专门提供图表的类库。它使得作图变成了一件非常简单的事情，你只需从数据库中取出相关数据，定义标题，图表类型，然后的事情就交给JpGraph，只需掌握为数不多的JpGraph内置函数（可以参照JpGraph附带例子学习），就可以画出非常炫目的图表
