This article mainly introduces the method of using Jpgraph to draw simple X-Y coordinate diagrams in PHP, and analyzes the related techniques of Jpgraph to draw coordinate diagrams and curves with examples. I hope to be helpful.
The specific implementation method is as follows:
SetScale("textlin"); //设置刻度样式 $graph->img->SetMargin(30,30,80,30); //设置图表边界 $graph->title->Set("Year to Date Cost"); //设置图表标题 // Create the linear plot $lineplot=new LinePlot($data); // 创建新的LinePlot对象 $lineplot->SetLegend("Amount(M dollars)"); //设置图例文字 $lineplot->SetColor("red"); // 设置曲线的颜色 // Add the plot to the graph $graph->Add($lineplot); //在统计图上绘制曲线 // Display the graph $graph->Stroke(); //输出图像 ?>
