PHP生成折线图和饼图等

pchart类库下载（地址：http://pchart.sourceforge.net/documentation.php） , 下载过后其中也有相应的例子，供选择

生成折线图

include("pChart/pData.class");  
include("pChart/pChart.class");  
// Dataset definition
$DataSet = new pData;
$DataSet->AddPoint(array(100,320,200,10,43),"Serie1");
$DataSet->AddPoint(array(20190726,20190727,20190728,20190729,20190730),"Serie3");
$DataSet->AddSerie("Serie1");
$DataSet->SetAbsciseLabelSerie("Serie3");
// Initialise the graph   
$Test = new pChart(700,230);
$Test->setFontProperties("Fonts/tahoma.ttf",8);
$Test->setGraphArea(85,30,650,200);
$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);
$Test->drawGrid(4,TRUE,230,230,230,50);
$Test->setFontProperties("Fonts/tahoma.ttf",6);
$Test->drawTreshold(0,143,55,72,TRUE,TRUE);
$Test->drawLineGraph($DataSet->GetData(),$DataSet->GetDataDescription());
$Test->drawPlotGraph($DataSet->GetData(),$DataSet->GetDataDescription(),3,2,255,255,255);
//生成图表
$imageFile = "1.png";
$Test->Render($imageFile);
echo '<img src="'.$imageFile.'">';

生成饼图
