@Carl Love thank you so much for the help, now i can get on with my bachlor project!:) and @tomleslie 159, i shall upload it to the site from now on, was completely oblivious to the upward pointing arrow until now. 

@Carl Love 

Here are the files:

mw: http://www.filedropper.com/plotscript_2

data1: http://www.filedropper.com/test1out

data2:http://www.filedropper.com/test1outpreciselarge

Yes i tried your solution, unfortunately, the problem was that once i converted the array, the converted list was only 1 element wide, not the 3 that are needed as points.

@tomleslie thank you for the feedback, the files have been uploaded to filedropper in a rar file. 

@Carl Love Wauw, i can't even blame myself for not detecting that one :S thank you very much for the quick help!:)
