Hi Monks, I'm trying to plot a chart in perl from the excel sheet that I also create in the program. Below is the actual code. If I understood it correctly, the $A and $B etc under "values" in add_series function are the excel column number. I'm facing a problem where it would plot data only if I put $A in it. No other column(tried $B, $CJ). I'll appreciate help with these questions: 1. Why is nothing being plotted if I try any column other than $A? 2. I need to automate it to pick the last column of any sheet. I couldn't figure a syntax to do that. 3. How do I automate the worksheet name “sim_*” to as many sheets I have? 


#!/usr/intel/pkgs/perl/5.14.1/bin/perl 

use Spreadsheet::WriteExcel;


$num_files = @ARGV[0];
print "Help - Syntax: 
       ./process_xyz.pl <number_of_csv_files> <all_csv_files>\n";

print " The output file is: xyz_stat.xls \n";
my $workbook                = Spreadsheet::WriteExcel->new('xyz_stat.x
+ls') or die $!;
my $worksheet_chart         = $workbook->add_worksheet('chart');

my $chart                   = $workbook->add_chart(type => 'line', emb
+edded => 1);

for ($k = 1; $k <= $num_files; $k++) {
  $stat_file[$k] = @ARGV[$k];
  open (_file, "$stat_file[$k]") or die "cannot open $stat_file[$k]";
  $frm_num = 0;
  $frm_start = 2;
  $frm_end   = 3;
  $tmp_var = "sim_$k";
  $worksheet[$k]            = $workbook->add_worksheet($tmp_var);

  while ($line = <_file>) {
    @frame_stats = split(/,/,$line);

    my $col = 0;
    foreach $el(@frame_stats) {
        $worksheet[$k]->write($frm_num, $col, $el);
        $col ++;
    }

    $frm_num++;
  }

}
  $chart->add_series(
#      categories => '=test1!$A$2:$A$10',
      values     => '=sim_1!$B$2:$B$361',
#      values     => '=sim_1!$A$2:$A$361',
      name       => 'sim1',
  );

  $chart->add_series(
#      categories => '=test1!$A$2:$A$10',
      values     => '=sim_2!$CU$2:$CU$361',
      name       => 'sim2',
  );

$worksheet_chart->insert_chart('E2', $chart, 15, 10);
