Thanks for helping me on my previous question; I was able to get it
afterwards. I have another question. I am trying to draw a graph.
First, I have created @1, @2, @3 within html. This prints out 3 columns with values
of each array on the array like below on a browser after calculation:
@X @Y @Z
1X 1Y 1Z
2X 2Y 2Z
. . .
. . .
Now, I want to create a bar graph of @1 and @2. The question I have is whether or not
I can do the following;
Section2:
my @dataforgraph = (@1,@2);
my $graph = GD::Graph::bars->new(1000, 1000);
$mygraph->set(
x_label => 'values of @X',
y_label => 'values of @Z',
title => '@X to @Z',
) or warn $mygraph->error;
my $myimage = $mygraph->plot([EMAIL PROTECTED]) or die $mygraph->error;
print "Content-type: image/png\n\n";
print $myimage->png;
Should I be placing the Section 2’s script within the html or after print end_html?
Also, is there possible way to place the graph next o the columns, instead of below
it? If so, do I use a function from Perl or have to design by using HTML? Can you
tell me what I should look up? Thanks for your help.
