我使用以下代码绘制图形，但没有成功：
<?php
$cwd = getcwd();
include($cwd."'pChart'class'pData.class.php");
include($cwd."'pChart'class'pDraw.class.php");
include($cwd."'pChart'class'pImage.class.php");
include($cwd."'pChart'class'pChart.class.php");
// Dataset definition
$DataSet = new pData;
$DataSet->AddPoint(array(1,4,3,2,3,3,2,1,0,7,4,3,2,3,3,5,1,0,7));
$DataSet->AddSerie();
$DataSet->SetSerieName("Sample data","Serie1");
// Initialise the graph
$Test = new pChart(700,230);
$Test->setFontProperties("Fonts/tahoma.ttf",10);
$Test->setGraphArea(40,30,680,200);
$Test->drawGraphArea(252,252,252);
$Test->drawScale($DataSet->GetData(),$DataSet->GetDataDescription(),SCALE_NORMAL,150,150,150,TRUE,0,2);
$Test->drawGrid(4,TRUE,230,230,230,255);
// Draw the line graph
$Test->drawLineGraph($DataSet->GetData(),$DataSet->GetDataDescription());
$Test->drawPlotGraph($DataSet->GetData(),$DataSet->GetDataDescription(),3,2,255,255,255);
// Finish the graph
$Test->setFontProperties("Fonts/tahoma.ttf",8);
$Test->drawLegend(45,35,$DataSet->GetDataDescription(),255,255,255);
$Test->setFontProperties("Fonts/tahoma.ttf",10);
$Test->drawTitle(60,22,"My pretty graph",50,50,50,585);
$Test->Render("Naked.png");
?>
与上相同http://pchart.sourceforge.net/documentation.php；任何帮助都将不胜感激。谢谢
自定义绘图图
自1.27b版本以来，可以将图片（仅支持GIF文件）与一个数据系列相关联。这张图将在绘制绘图图时替换小气泡。首先将一个图片与一个调用pData类的SetSeriesSymbol函数的序列相关联。使用drawTextBox函数将图表的标题写在图形区域上，该函数将透明度因子设置为30%
运行此脚本将在当前目录中创建一个example22.png文件。
输出：
<?php
// Standard inclusions
include("pChart/pData.class");
include("pChart/pChart.class");
// Dataset definition
$DataSet = new pData;
$DataSet->AddPoint(array(60,70,90,110,100,90),"Serie1");
