columnheader - How do I set axis label with column header in gnuplot? -


my question simple. suppose have datafile column headers, follows

first second 1 1  2 1 3 6 4 9

in gnuplot how make datafile plotted using column header axis label? e.g. calling

plot datafile using 1:2

i xaxis labeled first , yaxis labeled second?

edit: know can use column header key entry via set key auto title column head, that's not quite i'm looking for.

to elaborate suggestion of @andyras, here how can it:

datafile = 'filename.txt' firstrow = system('head -1 '.datafile) set xlabel word(firstrow, 1) set ylabel word(firstrow, 2) plot datafile using 1:2

you must plot explicit using statement, otherwise gnuplot complain bad data on line 1.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
