Dear All, I need a help to add a feature to my perl script. the script takes as input a file & finds the maximum & minimum value of it. Based on the min and max value you can defined the scale by using the bin size. (user input) For example bin size is 30 and min -100ps max 100ps then the scale to be -100 to -80, -80 to -60, -60 to -40, -40 to -20, -20 to 0, 0 to 20, 20 to 40, 40 to 60, 60 to 80, 80 to 100 Count the number of points falling in the scale range and display the file similar as shown below. 
-60 < x <= -30           (  6273 pts)  |**

 -30 < x <= 0                  ( 44623 pts)  |********

  0 < x <= 30                  ( 55626 pts)  +**********

  30 < x <= 60                 ( 11244 pts)  |**

please find the code below, 
my $file  = $ARGV[0]; # input file
my $bin    = $ARGV[1]; # bin size normally 20 or 30 
my $outfile    = "temp.stat";
open (IN_LOG,"$file") || die "cannot open $file for reading: $!";
open (OUT_LOG,">$outfile") || die "cannot open $outfile for writing: $
+!";
my $colName;
my @array;
while (<IN_LOG>) {
   push (@array,$_);
 }
}

my @sortArray = sort { $a <=> $b } @array;

$max = $sortArray[-1];
$min = $sortArray[0];

print OUT_LOG "#- - - - - - - - - - - - - - - - -  - - - -\n";
print OUT_LOG "#MAX : $max \n";
print OUT_LOG "#MIN : $min \n";
print OUT_LOG "#- - - - - - - - - - - - - - - - -  - - - -\n";
$temp=$max-$bin;
while ($max>=$min) { 
  $i=0;
  print OUT_LOG "\n$max > $bin < $temp:";
  foreach $val (@array) {
    if($val<=$max && $val>=$temp) {
      $i+=1;  
    }
   }
   $max= $temp;
   $temp=$temp-$bin;
   print OUT_LOG " $i pts ";
   my $star = int($i/500) + 0.5;
   $var= '*' x $star;
   print OUT_LOG "| $var\n ";
 
}
 
close IN_LOG;
close OUT_LOG;
close MYFILE;

currently i am able to sort the array & find the maximum & minimum values but not able to generate the scale/chart as shown above. the sampe of input file will be (as it is a huge file) 
45.980
-34.99
89.00
35.87
75.00
-30.173
-40.178
