more than one plot

what's wrong with the following code!

// Create a red line plot
$p1 = new LinePlot($datay);
$p1->SetColor("red");

// Create the 1st rate bar plot
$b1 = new BarPlot($databary1);
$b1->SetLegend("rate#1");
$b1->SetFillColor("orange");
$b1->SetAbsWidth(;

// Create the 2nd rate bar plot
$b2 = new BarPlot($databary2);
$b2->SetLegend("rate#2");
$b2->SetFillColor("Blue");
$b2->SetAbsWidth(;

// Create the 2nd rate bar plot
$b3 = new BarPlot($databary3);
$b3->SetLegend("rate#3");
$b3->SetFillColor("Yellow");
$b3->SetAbsWidth(;

// Drop shadow on bars adjust the default values a little bit
$b1->SetShadow("steelblue",2,2);
$b2->SetShadow("red",2,2);
$b3->SetShadow("Yellow",2,2);

// Create the grouped bar plot
$gbplot = new GroupBarPlot(array($p1,$b1,$b2,$b3));

then the stroke comes!

i can't find out what's wrong. i keep getting this msg:
JpGraph: Can't draw unspecified Y-scal.
you have either:
specified an Y axis for autoscaling but hanve not supplied any plots
specified a scale manually but have forgot to specify the tick steps

do some changes.

$gbplot= new GroupBarPlot(array($b1,$b2,b3));

then add ur group bar plot to ur graph

$graph->Add($gbplot);

//add ur line plot

$graph->Add($p1);

then ur stroke.

ope this helps..

there is a problem in this example code i downloaded with the jpgraph libraries!
any solutions?

<?php
include ("../jpgraph.php");
include ("../jpgraph_line.php");
include ("../jpgraph_error.php");

$errdatay = array(11,9,2,4,19,26,13,19,7,12);
$datax=array("Jan","Feb","Mar","Apr","May");

// Create the graph. These two calls are always required
$graph = new Graph(300,200,"auto");
$graph->img->SetMargin(40,30,20,40);
$graph->SetScale("textlin");
$graph->SetShadow();
$graph->xaxis->SetLabelAngle(0);
$graph->xaxis->SetFont(FF_ARIAL,FS_NORMAL,10);
$graph->img->SetAntiAliasing("white");

// Create the linear plot
$errplot=new ErrorLinePlot($errdatay);
$errplot->SetColor("red");
$errplot->SetWeight(2);
$errplot->SetCenter();
$errplot->line->SetWeight(2);
$errplot->line->SetColor("blue");
$errplot->SetLegend("Min/Max");
$errplot->line->SetLegend("Average");
// Add the plot to the graph
$graph->Add($errplot);

$graph->title->Set("Example 16");
$graph->yaxis->title->Set("Y-title");
$graph->yaxis->title->SetFont(FF_FONT1,FS_BOLD);
$graph->xaxis->title->Set("X-title");
$graph->title->SetFont(FF_FONT1,FS_BOLD);

$graph->xaxis->SetTickLabels($datax);
$graph->xaxis->SetTextTickInterval(2);

// Display the graph
$graph->Stroke();
?>

it's example16.php
