PHP 生成柱状图，折线图，饼状图——可保存本地文件

首先：并非原创，这次连二次开发都没算上，纯纯转载

我只是发现作者好像并没有把饼状图的调用方法写出来，于是读了一下代码，补在下面了。

项目结构：

---libchart
---linepic.php  ////生成折线图
---piepic.php   ////生成饼状图
---pillarpic.php ///生成柱状图

折线图生成的代码：

<?php
include "libchart/classes/libchart.php";
$chart = new LineChart();

$serie1 = new XYDataSet();
$serie1->addPoint(new Point("08-01", 50));
$serie1->addPoint(new Point("08-02", 30));
$serie1->addPoint(new Point("08-03", 150));
$serie1->addPoint(new Point("08-04", 600));
$serie1->addPoint(new Point("08-05", 450));
$serie1->addPoint(new Point("08-06", 800));

$serie2 = new XYDataSet();	
$serie2->addPoint(new Point("06-01", 280));
$serie2->addPoint(new Point("06-02", 300));
$serie2->addPoint(new Point("06-03", 212));
$serie2->addPoint(new Point("06-04", 542));
$serie2->addPoint(new Point("06-05", 600));
$serie2->addPoint(new Point("06-06", 850));

$dataSet = new XYSeriesDataSet();
$dataSet->addSerie("第一曲线的图例", $serie1);
$dataSet->addSerie("第二曲线的图例", $serie2);
$chart->setDataSet($dataSet);

$chart->setTitle("折线图表头");
$chart->render("line.png");

柱状图的生成代码：

<?php

include "libchart/classes/libchart.php";

$chart = new VerticalBarChart(600, 250);
$dataSet = new XYDataSet();

$dataSet->addPoint(new Point("蓄电池",878));
$dataSet->addPoint(new Point("空气滤清器",560));
$dataSet->addPoint(new Point("前减震器",429));
$dataSet->addPoint(new Point("后制片器",72));
$dataSet->addPoint(new Point("前制动盘",1));
$dataSet->addPoint(new Point("雨刷器",1));
$dataSet->addPoint(new Point("后减震器",1));

$chart->setDataSet($dataSet);
$chart->setTitle("配件统计信息");
$chart->render("pillar.png");

饼状图的生成代码：

<?php

include "libchart/classes/libchart.php";
$chart = new PieChart(500, 250);
$dataSet = new XYDataSet();

$dataSet->addPoint(new Point("学习",0.5));
$dataSet->addPoint(new Point("娱乐",560));
$dataSet->addPoint(new Point("生活",429));
$dataSet->addPoint(new Point("其他",72));

$chart->setDataSet($dataSet);


$chart->setTitle("饼状图");
$chart->render("pie.png");

不得不说，确实比网上好多源码做得好了
