Re^2: parse a csv file and create array of arrays and then plot the data

:) i dont want anyone to write it for me. Even though looking at what i wrote looks that way. My Question is: In the code, i have the following as sample data

my $data = [
    [ 0,500,1000,1500,2000,2500,3000,3500,4000 ],
    [ 1000, 450, 550, 240, 120, 330 ],
    [ 3000, 650, 750, 555, 440, 550 ],
];

I tried substituting the individual arrays in $data with: $column4 because the array reference $column4 is in a while loop so what i need is a hint of how to incorporate $column in $data
