Plotting data from a file - comp.graphics.apps.gnuplot

Hi, I'm using gnuplot 4.4.0 on OS X 10.6.2 and am trying to plot the file ecut.txt which looks like #Ecut Length Atomisation Energy 10 0.805312626 0.165625435 15 0.794875914 0.171276982 20 0.782939689 0.173722651 25 0.775818652 0.174689776 30 0.772 0.175219486 35 0.772614854 0.175525673 40 0.772084357 0.175793694 45 0.771989336 0.176002384 50 0.771522545 0.176162818 with the command (e.g) plot 'ecut.txt' using 1:2 and get the response warning: Skipping unreadable file "ecut.txt" No data in plot What am I doing wrong? Cheers.

The error message is really quite clear, isn't it? Gnuplot could not read the file. Likely as not, that's because whatever program created the file doesn't allow other programs to open it (yet), or you're simply running gnuplot from a directory other than the one that file is in.

Hi! Or - in addition to what Hans-Bernhard Br�ker wrote: You might simply have forgotten the ".txt" at the end of the file name... I am also working on OS X - and whenever that error appears, I have - by some misclicking in the editor's save-dialog - overridden the file extension - and OS X won't save it, if You don't ask it to do... I would check for that, it is most probably the case... (if You haven't already...). Best, Bj�rn

Hey I to support 'bbcda's' point. U might be skipping the extension of the file.
