PHP generates line charts, pie charts, etc.

pchart class library download (address: http://pchart.sourceforge.net/documentation.php), there are also corresponding examples for selection after downloading

Generate line chart

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 '';

Generate pie chart

AddPoint(array(100,320,200,10,43,417),"Serie1"); $DataSet->AddPoint(array("20190726","20190727","20190728","20190729","20190730","20190731"),"Serie2"); $DataSet->AddAllSeries(); $DataSet->SetAbsciseLabelSerie("Serie2"); // Initialise the graph $Test = new pChart(500,200); $Test->setFontProperties("Fonts/tahoma.ttf",8); $Test->drawFilledRoundedRectangle(7,7,293,193,5,240,240,240); $Test->drawRoundedRectangle(5,5,295,195,5,230,230,230); // Draw the pie chart $Test->AntialiasQuality = 0; $Test->setShadowProperties(2,2,200,200,200); $Test->drawFlatPieGraphWithShadow($DataSet->GetData(),$DataSet->GetDataDescription(),120,100,60,PIE_PERCENTAGE,8); $Test->clearShadow(); $Test->drawPieLegend(230,15,$DataSet->GetData(),$DataSet->GetDataDescription(),250,250,250); $imageFile = 'example12.png'; $Test->Render($imageFile); echo ''; ?>
