Hi, I have a 2D array where each element is a dot or a space. Along the margins I have two strings that I compare and print a dot if there is a match. The output file is too large to attach but right now it's printing to a text file.

I would like to know is it possible to use GD to either convert the file to a graph or just create a graph directly so that the plot could be viewed in a single window without the dots being made smaller (i.e. reduce the whitespace in the file so that the dots would be closer together in a single graph). I could probably make the x- and y- axes numerical using the length of the strings but the strings are ~1500 characters long so I would need to compress this.

I have looked at GD and tried to achieve it but couldn't get it to work. I would be very grateful if you could provide some guidance on how to achieve this if it is possible.

In reply to GD module help please by egorleg
