Skipping data file with no valid points

Show all headers | View raw

Hello,

I have a single .xlsx file that contains the data I'd like to plot.  After reading Gnuplot in Action I only see Janert using .dat & .txt file formats.  So, on my mac I 'save as' to .txt 'tab delimited' (as opposed to the other two .txt options of MS-DOS & Windows formatted).  Then I navigate to the directory of interest in Terminal, launch gnuplot and type -- plot "trial.txt" u 1:3 w lp  -- with no luck (warning: Skipping data file with no valid points).

I tried adding a # to the first line.  I tried alternative .txt formats.  I manually re-created the first ten entries in my TextEdit app only to find out there is no save as option for .txt files (wtf?).  Then I re-created in Xcode which saved it with no file extension BUT it plots as expected.  Copying and pasting from the xlsx file into a blank Xcode file and saving also works as expected.  

Can someone provide pointers so that I do not have to do this each time I want to play with my data?

In case it was not obvious, I am within my first 4 hours learning gnuplot - and Janert's book is great but I'm having trouble getting going with real data sets I'd like to analyze.

Thanks.
