I read the filters documentation and I typed the following code for example:
[% FILTER null;
data = [ ["1st","2nd","3rd","4th","5th","6th"],
[ 4, 2, 3, 4, 3, 3.5] ];
USE my_graph = GD.Graph.pie( 250, 200 );
my_graph.set(
title => 'A Pie Chart',
label => 'Label',
axislabelclr => 'black',
pie_height => 36,
transparent => 0,
);
my_graph.plot(data).png | redirect("/home/savio.png", binmode=1);
END; -%]
taken from:
http://perl.asylog.net/perl5.6.1/site_perl/5.6.1/sun4-solaris/Template/Plugin/GD/Graph/pie.html
I changed stdout(1) with redirect("/home/savio.png", binmode=1);
but I have the following error:
Software error:
redirect error - OUTPUT_PATH is not set
