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(); ?>
