I can now see my data. Current view: https://s15.postimg.org/ni570gxl7/pyscreenshot2.png Yes, you are correct on how the points are going to be plotted. My question is, how do you plot only rows on python? I found an example online, but the data is in columns. (http://www.ast.uct.ac.za/~sarblyth/pythonGuide/PythonPlottingBeginnersGuide.pdf, pg. 14). How do I change this particular part on the example so it reads the rows: pl.plot(data[:,0], data[:,1], ’ro’):: Or will this not work in this case? I was thinking of making two arrays like this: x=np.array [] and y=np.array[] and the inserting the data between the brackets, but then though wouldn't that defeat the purpose of the file?

Yes, that will only work once you get the file path sorted out. -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ http://www.amazon.com/author/alan_gauld <http://www.amazon.com/author/alan_gauld> Follow my photo-blog on Flickr at: http://www.flickr.com/photos/alangauldphotos <http://www.flickr.com/photos/alangauldphotos> _______________________________________________ Tutor maillist - Tutor@python.org <mailto:Tutor@python.org> To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor <https://mail.python.org/mailman/listinfo/tutor> _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
