thanks guys, the following problem is solved now.

hi, i hope that someone can help me with this.
the array @xValues is a reference. how can i find out the length of the array? i have used

Code:

length(@xValues)
@xValues.length

already, but it only enters my loop once.
if i use

Code:

@{$#xValues}

, then it doesn'e even enter the loop at all.
please help!
thank you.

Code:

else
   {
   print "elsif loop\n";
#@{$#xValues}
      $number = $maxDataY - $minDataY;
      $scale = ($height - 60) / $number;
      $i = 0;
      
      for ($j = 0; $j < @{$#xValues}; $j++) # here i need to know the length of the array
      {
      print "for loop\n";
         
         $xCoordinate = $X + @$xValues[$i] - $minDataX;
         $yCoordinate = int($Y + (@$yValues[$i] * $scale));
         $i++;
         $xCoordinate2 = $X +@$xValues[$i] - $minDataX;
         $yCoordinate2 = int($Y + (@$yValues[$i] * $scale));
         $$page->color( $red, $green, $blue,'RG');
         print "color($red, $green, $blue, 'RG')\n";
         $$page->line($xCoordinate, $yCoordinate, $xCoordinate2, $yCoordinate2);
         
         print "line($xCoordinate, $yCoordinate, $xCoordinate2, $yCoordinate2)\n";
      }# end for
   }# end else
