$graph->SetAxisLabelBackground(LABELBKG_NONE,'orange','red','lightblue','red');

// Use Ariel font
// $graph->xaxis->SetFont(FF_ARIAL,FS_NORMAL,9);
// $graph->yaxis->SetFont(FF_ARIAL,FS_NORMAL,9);
$graph->xaxis->SetFont(FF_FONT1,FS_NORMAL,9);
$graph->yaxis->SetFont(FF_FONT1,FS_NORMAL,9);
$graph->xgrid->Show();

// Create the plot line
$p1 = new LinePlot($ydata);
$graph->Add($p1);

// Output graph
$graph->Stroke();

この例では、データを$ydate=array(....)の箇所でセットしています。
