//  data

$ydata = array(90,80,67,87,66,71,96,53,35,73);

// Create the graph. These two calls are always required

$graph = new Graph(300,250);

$graph->SetScale('textlin');

$graph->xaxis->title->Set("Number of students");

$graph->yaxis->title->Set("Marks");

// Create the linear plot

$lineplot=new LinePlot($ydata);

$lineplot->SetColor('blue');

// Add the plot to the graph

$graph->Add($lineplot);

// Display the graph

$graph->Stroke();

?>
