I've been reading the documentation that JPGraph offers but the class doesn't seem to be generating a graph. The code has no syntax error nor does JP report any errors but nothing is returned to the browser.
I'm running a loop that runs 12 times, 1 for each month. This is the code I have at the moment, hopefully somebody can spot an error with the way I'm using JP. Having all the graphs in 1 images isn't really a concern, multiple images on 1 page would suit me better to be fair. I've tried looping 12 times through a standard bar chart but nothing is returned then either.
Code: Select all
for($i = 1; $i <= 12; $i++) {
foreach($orders as $rName => $array) {
foreach($array as $month => $numOrders) {
$leg[] = $rName;
if($i == $month)
$data{$i}[] = $numOrders;
}
}
$graph{$i} = new Graph(1300,700);
$graph{$i}->SetScale("textlin");
$graph{$i}->SetFrame(false);
$graph{$i}->yaxis->title->Set("No. Orders");
$graph{$i}->title->Set("Graph");
$graph{$i}->xaxis->SetTickLabels($leg);
$graph{$i}->xaxis->SetLabelAngle(90);
$bplot{$i} = new BarPlot($data);
$bplot{$i}->SetFillColor("blue");
$bplot{$i}->value->SetFormat('%d');
$bplot{$i}->value->Show();
}
$mgraph = new MGraph();
$xpos1=3;$ypos1=3;
$xpos2=3;$ypos2=200;
$mgraph->Add($graph1,$leg,$data);
$mgraph->Add($graph2,$leg,$data);
$mgraph->Stroke();
