A quick Google tells me that SetLegends is for a pie chart. I think you need to set the legends individually as the chart is created, from this code I found:

PHP Code:

for ($i=0; $i < $tg; $i++) {                  // total groups 
  $bplot[$i] = new BarPlot($datay[$i]); 
  $bplot[$i]->SetFillColor($color[$i]); 
  $bplot[$i]->SetLegend($groupU[$i]); 
} 
$gbarplot = new GroupBarPlot($bplot); 


This page seems to contain all the information you might need [The wonders of Google ].

Then this page tells you how to position and customize the legend.

PHP Code:

$bplot1->SetFillColor("orange");
$bplot2->SetFillColor("brown");
$bplot3->SetFillColor("darkgreen");

$bplot1->SetLegend("Pass");
$bplot2->SetLegend("Fail");
$bplot3->SetLegend("NotEligible")

$gbarplot = new GroupBarPlot(array($bplot1,$bplot2,$bplot3));
$gbarplot->SetWidth(0.6);
$graph->Add($gbarplot);

$graph->Stroke();
