php jpgraph

I want to move the y-axis line over as the numbers overlap with the y-axis title. It's been a long time since I worked with jpgraph and found little or no documentation on moving just the line so larger numbers don't overlap the title.

Here is some example code I am using to play around with the position of the graph. See attached image.

<?php

require_once ('jpgraph/src/jpgraph.php');
require_once ('jpgraph/src/jpgraph_line.php');

$ydata = array(11,3,598,412,5,901,9,13,5,7);
$y2data = array(354,200,265,99,111,91,198,225,293,251);

// Create the graph and specify the scale for both Y-axis
$graph = new Graph(600,400,'auto');
$graph->SetScale('textlin');
$graph->SetY2Scale('lin');
$graph->SetShadow();
 
// Adjust the margin
$graph->img->SetMargin(80,140,20,40);
 
// Create the two linear plot
$lineplot=new LinePlot($ydata);
$lineplot2=new LinePlot($y2data);
 
// Add the plot to the graph
$graph->Add($lineplot);
$graph->AddY2($lineplot2);
$lineplot2->SetColor('orange');
$lineplot2->SetWeight(2);

// Adjust the axis color
$graph->y2axis->SetColor('orange');
$graph->yaxis->SetColor('blue');

$graph->yaxis->scale->ticks->Set(20, 20);

$graph->title->Set('Example 6');
$graph->xaxis->title->Set('X-title');
$graph->yaxis->title->Set('Y-title');

$graph->title->SetFont(FF_FONT1,FS_BOLD);
$graph->yaxis->title->SetFont(FF_FONT1,FS_BOLD,12);
$graph->xaxis->title->SetFont(FF_FONT1,FS_BOLD);

// Set the colors for the plots
$lineplot->SetColor('blue');
$lineplot->SetWeight(2);
$lineplot2->SetColor('orange');
$lineplot2->SetWeight(2);

// Set the legends for the plots
$lineplot->SetLegend('Plot 1');
$lineplot2->SetLegend('Plot 2');

// Adjust the legend position
$graph->legend->Pos(0.05,0.5,'right','center');

      // Display the graph
      //$graph->Stroke();
      $gdImgHandler = $graph->Stroke(_IMG_HANDLER);
      $rand = date("U");
      $fileName = ".output/$rand.png";
      $graph->img->Stream($fileName);
      print "<img src=\"$fileName\"><br>";
?>

Have you tried fiddling with SetMargin?

You need to play with:
$graph->SetMargin(x,y,z,w);
$graph->yaxis->title->SetMargin(5);

Thanks Dan! That was the trick. I though I tried that but guess not.
