php uses Jpgraph to draw a simple X-Y coordinate graph, jpgraphx-y

This article describes the example of php using Jpgraph to draw a simple X-Y coordinate graph. Share it with everyone for your reference. The specific implementation method is as follows:

<&#63;php 
include ("src/jpgraph.php"); 
include ("src/jpgraph_line.php"); 
//将要用于图表创建的数据存放在数组中 
$data = array(19,23,34,38,45,67,71,78,85,87,90,96); 
$graph = new Graph(400,300); //创建新的Graph对象 
$graph->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 
&#63;>

The rendering after operation is as follows:
