Re: products with multiple variables

[Jonathan Callahan <Jonathan.S.Callahan@xxxxxxxx>]

Chris,

Greatly belated kudos for getting Vis5D output working.  I would be 
interested in seeing it and possibly including it in our 'las/contrib/' 
area.  Various default LAS products deal with multiple variables.

If you look in Ferret.pl for the subroutine 'sub data' you'll see the 
following code that deals with multiple variables:

my $vararray = $props->{variable_name};
my @vars = ref($vararray) eq "ARRAY" ? @{$vararray} : ($vararray);

...

The bottom line is that the list of variables is available in 
$self->{props}->{variable_name} which is a reference to an array.  Look 
in las/server/log/debug to see this.

If you write templated journal scripts you can pass the template this 
array of variables and use the templating language to loop through the 
array.   Contact me for further details if you'd like to pursue this route.
