Hi monks, Wondered if you could help -

I have a data-file which has numerical information on up to 96 different positions on a grid. e.g no 12 may be missing etc but the scale is from 1-96.

I am iterating through these lines in a foreach loop, extracting the grid reference number (1-96) and computing a clickable image leading to graphs etc for each position.

The problem is occuring when a particular number is missing, e.g if number 12 is missing graphs are produced for 1-95, not 1-11 and 13-96, meaning the grid number does not correspond to the graph created. I have tried using counters etc to get around this problem but nothing i working - I wondered if anyone had a simple logical way to get around this. Thankyou. 



foreach my $line (@grid)       {


      $line =~ s/^(\d+){1,2}//;
      $grid_no = $1;

      # @numbers and @data irrelevent

      $plot = plot_graph (\@numbers, \@data, $grid_no);
    
      push @graph_links, $plot . ' ';

  }

my $graph_links  = join ('', @graph_links);
@graph_links = split (/\s+/, $graph_links);


print qq(<P>Please click on a spot! <P>);
print qq(<P><div align=center><img src=array.bmp border=0 usemap=#arra
+y><map name=array><P>);
print qq(<area href="http://biolarfs1/~khh103/cgi-bin/$graph_links[0]"
+ ALT="" shape="circle" coords="13,9,6">);

## etc ..........
