本文實例講述了php使用Jpgraph繪制柱形圖的方法。分享給大家供大家參考。具體實現方法如下:
<?php include ("src/jpgraph.php"); include ("src/jpgraph_bar.php"); $data = array(19,23,34,38,45,67,71,78,85,87,90,96); //定義數組 $graph = new Graph(400,300); //創建新的Graph對象 $graph->SetScale("textlin"); $graph->SetShadow(); //設置陰影 $graph->img->SetMargin(40,30,20,40); //設置邊距 $barplot = new BarPlot($data); //創建BarPlot對象 $barplot->SetFillColor('blue'); //設置顏色 $barplot->value->Show(); //設置顯示數字 $graph->Add($barplot); //將柱形圖添加到圖像中 $graph->title->Set("年度收支表"); //設置標題和X-Y軸標題 $graph->xaxis->title->Set("月份"); $graph->yaxis->title->Set("總金額(兆美元)"); $graph->title->SetFont(FF_SIMSUN,FS_BOLD); //設置字體 $graph->yaxis->title->SetFont(FF_SIMSUN,FS_BOLD); $graph->xaxis->title->SetFont(FF_SIMSUN,FS_BOLD); $graph->Stroke(); ?>
運行效果如下圖所示:
希望本文所述對大家的php程序設計有所幫助。
