Hello,

I have a hash:

$hash{$x_label}{$y_data}{$uri}

with at least 5 different $uri

and I have different x_label and y_data for each uri (x_label is timestamp "%H:%i" and y_data is clicks per minute), that I need to feed GD::Graph @data with.

The problem is that NO uri have the same number of data points and I want to display CPM over TIMESTAMP for each URI, along with the x_label TIMELINE.

The following code:

foreach my $x_label (sort keys %hash_data){
        foreach my $uri (keys %{$hash_data{$x_label}}){
                print "x: $x_label - value: $hash_data{$x_label}{$uri}
+ ($uri)\n";
        }
}

The question is, how do I generate arrays with the same size, for each url, to feed GD::Graph with a proper @data?

I'm trying with multidimensional arrays, but still could not figure out how to code to solve that problem, any thoughts?

thanks
