PHP - How To Color Label When Passing Value "0"

Hi All,

I am currently using jpgraph on a site, and I'm trying to get the (x,y) coordinates an a chart to have two different colors ... (x = green, y = red)

You can see an example he
http://entropylinks.com/testgraph-dev.php?energy=2.2&entropy=1.75

Here is my code:
Code: [Select]
<?php // content="text/plain; charset=utf-8"
require_once ("graph/src/jpgraph.php");
require_once ("graph/src/jpgraph_scatter.php");
 DEFINE('MATRIX','images/matrix-big-2.png');
 $datax = array(0,3);
 $datay = array(0,3);
 if(isset($_SESSION['counter']) && $_SESSION['counter'] > 1){
$x = 1.98;
$y = 1.2;
$count = $_SESSION['counter'];
for($i = 0; $i < $count; $i++){
$datax[] += $_SESSION["entropy_$i"];
$datay[] += $_SESSION["energy_$i"];
}
}
else
{
$datax = explode('-', $_GET['energy']);
$datay = explode('-', $_GET['entropy']);
} 

$idx=0;
function xyCallback($yval) {
  global $datay, $idx;
  return "($yval-".$datay[$idx++].")";
}
 
$graph = new Graph(550,550);
$graph->SetScale("intint",0,3,0,3);
$graph->img->SetMargin(40,40,40,40);        
$graph->SetBackgroundImage(MATRIX,BGIMG_FILLPLOT);
$graph->title->SetFont(FF_ARIAL,FS_BOLD);
$graph->xaxis->SetTitle('CORPORATE ENTROPY','middle'); 
$graph->yaxis->SetTitle('CORPORATE ENERGY','middle'); 
$graph->yaxis->SetTextTickInterval(1,2);
 
$sp1 = new ScatterPlot($datax,$datay);
$sp1->mark->SetSize(10); 
$sp1->mark->SetFillColor("darkblue");
$sp1->mark->SetType(MARK_FILLEDCIRCLE);

$sp1->value->SetMargin(17);

$sp1->value->SetFormatCallback('xyCallback');
$sp1->value->SetColor("darkgreen");

$sp1->value->SetFont(FF_FONT0,FS_NORMAL);

$sp1->value->Show();


$txt = new Text("Low"); // store text
$txt->SetFont(FF_FONT0,FS_NORMAL); 
$txt->SetScalePos(0.5,0);
$txt->SetColor('darkblue'); 
$txt->Center(50,150,75); 
$graph->AddText( $txt); // write to position



$txt = new Text("Medium"); // store text
$txt->SetFont(FF_FONT0,FS_NORMAL); 
$txt->SetScalePos(1.5,0);
$txt->SetColor('darkblue'); 
$txt->Center(50,150,75); 
$graph->AddText( $txt); // write to position



$txt = new Text("High"); // store text
$txt->SetFont(FF_FONT0,FS_NORMAL); 
$txt->SetScalePos(2.5,0);
$txt->SetColor('darkblue'); 
$txt->Center(50,150,75); 
$graph->AddText( $txt); // write to position




$txt = new Text("Low"); // store text
$txt->SetFont(FF_FONT0,FS_NORMAL); 
$txt->SetScalePos(-0.03,0.5);
$txt->SetAngle(90); 
$txt->SetColor('darkblue'); 
$txt->Center(50,150,75); 
$graph->AddText( $txt); // write to position



$txt = new Text("Medium"); // store text
$txt->SetFont(FF_FONT0,FS_NORMAL); 
$txt->SetScalePos(-0.03,1.5);

$txt->Center(50,150,75); 
$graph->AddText( $txt); // write to position



$txt = new Text("High"); // store text
$txt->SetFont(FF_FONT0,FS_NORMAL);

$txt->SetAngle(90); 
$txt->SetColor('darkblue'); 
$txt->Center(50,150,75); 
$graph->AddText( $txt); // write to position

$graph->Add($sp1);

$graph->Stroke();

Does anyone have a solution for this?

Is it even possible?

Do I need to somehow modify the class to render these different colors?

Feel free to ask any questions you may have, I'm 99% complete with this, but I just can't seem to change the colors of the plot labels.

Thanks!

Is it possible to have a link at the top of a page that has been displayed from a database? Just that some results show thousands of rows. Thanks.

Hi,
I have a select menu like this:

Now I am outputting the result of the currency conversion like this:

Code: [Select]
<?php echo $currency_amount?> &euro; = <?php echo $total_euros?> <?php echo HERE_I_WANT_THE_CURRENCY_NAME?>but because the select men labels are not dynamically pulled from my DB (due to the way the DB had to be done), I can't figure out how to echo the currency name at the end of the conversion result.
Any ideas?...Thanks

ok i think and hope this will be my last issue with this site.

i have two forms on the same contact page, but right now theyre using the same error label. this means if ONE has an error, both forms show as that same error.  id like to somehow separate this and give each one its own label.
i tried doing like error[2] for the 2nd button instead of error[] but then i didnt know what to change the actual "error label" to. do i changed the "$errors = array();" part? to create a second label? i tried to google on it and couldnt figure it out.  thanks a million to anyone who even reads

<?php
if (isset($errors)) {

foreach ($errors as $error) {

echo("<p>$error<p>\n");

}
}
?>

so my question basically is, how do i use this code below to create a second error case AND label please!!

<?php
if ($_POST['send']) {

$errors = array();

if ($_POST['captcha'] != $_SESSION['captchacode']) {

$errors[] = "You didn't enter the correct letters!";
}



+
<?php
if (isset($errors)) {

foreach ($errors as $error) {

echo("<p>$error<p>\n");

}
}
?>

Hello.

I have a basic form and I want to check for errors by making sure the user inputs everything, if not an error explaining to the user what needs to be fixed. (very common on all forms)

When I use echo in my script, it displays at the top of my browser.  How do I put the error codes right beside my form elements?
I currently don't have all the error checking included but I want to get a few sorted out before anything else.
