Hi!

I was wondering on how I can send values through php so that JpGraph would take them to plot graphs?

Thanks

This is an example that uses JPGraph:

PHP Code:

require_once("jpgraph.php");

require_once("jpgraph_bar.php");



// example - fill array 'databary2' with 12 values, one for each month

$databary2[] = '23';

$databary2[] = '34';

$databary2[] = '92';

$databary2[] = '71';

$databary2[] = '15';

$databary2[] = '16';

$databary2[] = '45';

$databary2[] = '66';

$databary2[] = '8';

$databary2[] = '69';





$datax=array("Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec");



// New graph with a drop shadow 

$graph = new Graph($xdim,$ydim,"auto");

$graph->SetScale("textlin"); 

$graph->SetShadow(); 



// left,right,top,bottom

$graph->img->SetMargin(40,30,20,60); 



// Create the bar plots 

//$b1plot = new BarPlot($databary1); 

//$b1plot->SetFillColor($gcolor1); 

$b2plot = new BarPlot($databary2); 

$b2plot->SetFillColor($gcolor2); 



//$b1plot->SetLegend("Scheduled"); 

$b2plot->SetLegend("Actual"); 



if ($useLabels == "on"){

    //$b1plot->value->SetFormat('%d');

    //$b1plot->value->Show(); 

    $b2plot->value->SetFormat('%d');

    $b2plot->value->Show(); 

    // set y-grace

    $graph->yaxis->scale->SetGrace(6,auto);

}else{

    $graph->yaxis->scale->SetGrace(3,auto);

}



// add the credit line if graph is big enough

if($xdim > 300){

$txt =new Text("SomeSite.com"); 

$pos1 = ($xdim - 120);

$pos2 = ($ydim - 22);

$txt->Pos( $pos1,$pos2); 

$txt->SetColor( "black"); 

$graph->AddText( $txt); 

}





// use a bar shadow if set

if ($shadow == "on"){

 // $b1plot->SetShadow($aShadowColor,$aShadowWidth);

  $b2plot->SetShadow($aShadowColor,$aShadowWidth);

}



$graph->legend->SetAbsPos($xlabel,$ylabel,'left','bottom'); 

$graph->legend->SetColumns(3); 

$graph->legend->SetFont(FF_FONT1,FS_NORMAL,14); 

$graph->legend->SetFillColor('#ffffff');



// Setup month on X-scale

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



// Create the grouped bar plot 

$gbplot = new GroupBarPlot(array($b1plot,$b2plot)); 



// ...and add it to the graPH 

$graph->Add($gbplot); 



// Set title and subtitle 

$graph->title->Set("$statYear - Legend For Sample Graph"); 

$graph->xaxis->title->Set("Month"); 

$graph->yaxis->title->Set("Days with Contact"); 



if($xdim > 400){

    $graph->title->SetFont(FF_FONT2,FS_BOLD); 

}else{

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

}

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

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



// Finally output the  image 

$graph->Stroke();

Thanks?

Anyway I could send that through a variable? (example.php?value1=[etc...]&value2=[...]

???

Just a quick modifcation of End User's code, but receiving data from within the URL, this should work. (I only modified how the array is being populated).

PHP Code:

require_once("jpgraph.php");

require_once("jpgraph_bar.php");



// example - fill array 'databary2' with 12 values, one for each month

$databary2[] = $_GET['value1'];

$databary2[] = $_GET['value2'];

$databary2[] = $_GET['value3'];

$databary2[] = $_GET['value4'];

$databary2[] = $_GET['value5'];

$databary2[] = $_GET['value6'];

$databary2[] = $_GET['value7'];

$databary2[] = $_GET['value8'];

$databary2[] = $_GET['value9'];

$databary2[] = $_GET['value10'];

$databary2[] = $_GET['value11'];

$databary2[] = $_GET['value12'];



$datax=array("Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec");



// New graph with a drop shadow 

$graph = new Graph($xdim,$ydim,"auto");

$graph->SetScale("textlin"); 

$graph->SetShadow(); 



// left,right,top,bottom

$graph->img->SetMargin(40,30,20,60); 



// Create the bar plots 

//$b1plot = new BarPlot($databary1); 

//$b1plot->SetFillColor($gcolor1); 

$b2plot = new BarPlot($databary2); 

$b2plot->SetFillColor($gcolor2); 



//$b1plot->SetLegend("Scheduled"); 

$b2plot->SetLegend("Actual"); 



if ($useLabels == "on"){

    //$b1plot->value->SetFormat('%d');

    //$b1plot->value->Show(); 

    $b2plot->value->SetFormat('%d');

    $b2plot->value->Show(); 

    // set y-grace

    $graph->yaxis->scale->SetGrace(6,auto);

}else{

    $graph->yaxis->scale->SetGrace(3,auto);

}



// add the credit line if graph is big enough

$pos1 = ($xdim - 120);

$graph->legend->SetColumns(3); 

$graph->legend->SetFont(FF_FONT1,FS_NORMAL,14); 

$graph->legend->SetFillColor('#ffffff');

Sure, I do it all the time to pass other parameters like color, shadow status, etc.
