Making a guess from your data, maybe something like this might work?

#! perl -slw
use strict;
use GD::Graph::bars;

my @data = (
    [ qw (   A   B   C ) ],
    [ qw ( 100 300 150 ) ],
    [ qw ( 200 100 100 ) ],
);

my $graph = GD::Graph::bars->new(400, 300);

$graph->set(
    show_values => 1,
    x_label           => 'Store',
    y_label           => 'Sales',
    title             => 'Sales/Store/Quarter',
    y_max_value       => 400,
    y_min_value       => 000,
    y_tick_number     => 8,
    y_label_skip      => 1,
    bargroup_spacing  => 10,
) or die $graph->error;

$graph->set_legend( qw[ Q1 Q2 ]);

my $gd = $graph->plot(\@data) or die $graph->error;

open(IMG, '>file.gif') or die $!;
binmode IMG;
print IMG $gd->gif;
close IMG;

I had the same idea, but like always the best answer depends on information we don't have about the original data!

Like whats the maximum timespan, number of stores and expected information gain.

I guess that distinguishing up to 20 stores by color or symbols should be sufficient to represent them all into one 2D chart (Sales x Time). Connecting the points might help:

Like here or even with perspective.

Looking at your small excerpt it seems to me you could combine @x and @y into a single array and use it as labels on the x axis, and you could use @z as the values on the y axis.

Hi Mortiz,

Yes that can be done, But in my case it's going to be huge number of combination (Cartesian). So X values going to be really messy.

My idea was, graph will be having one X-Axis with X values and one Y-Axis with Y values. There will not be any Z axis but in the canvas it'll show the values.

So it sounds you either want a 3D plot, or a density plot/heat map where the z value is encoded in the color.

I have done neither with Perl so far, but these key words should give you an idea what to search for. A quick search showed up tridens, which might do what you want.

Perl 6 - second systems done right

You want to represent a set of 3D points in a 2D plane with the z coordinates plotted as values?

This can only work if 2 points never have the same x/y coordinates.

Like showing a map for New York's skyscraper's from above by plotting the heights, this can only work because buildings "rarely" share the same coordinates.

Are you sure your data fits into this criteria?

Anyway the words "matrix" and "graph" are misleading, graphs are normally represented as connected lines, not plotted points.

And representations of matrices have a equidistant grid, i.e. a tabular structure.

If the latter is the case (and that's what your data looks like) you could simply use perl's format to plot your z-values.

Hi All, thanks for the responses.

To get more clarity, I have uploaded one sample graph here

The linked graph is a type of scattergram, but it is quite hard to relate that to your sample data?

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority".

In the absence of evidence, opinion is indistinguishable from prejudice.

You want to represent z-values by colors within a x/y-grid?

Cheers Rolf

Maybe try using perl + gnuplot, similar to what's shown here: http://www.oreillynet.com/pub/a/sysadmin/2007/02/02/3d-logfile-visualization.html ?
