I'm new to gnuplot. I am reading the manual but am having a hard time finding explanations for some of the abbreviations people use in their scripts. For example, I am working with an script that says:

f(x)=invnorm(x)
g(x)=norm(x)

plot \
    "file.curve" u (f($3)):(f($2)) ti "Curve 1" ls 1 lw 3, \
    "file.curve" u (f($3)):(f($2)) ti "Curve 2" ls 2 lw 3, \
    "file.curve" u (f($3)):(f($2)) ti "Curve 3" ls 3 lw 3, \
    f(1-g(x)) noti lt rgb "#FF0000" lw 0.75, \
    f(12.5*g(x)) noti lt rgb "#808080" lw 0.75

I think I understand that ti stands for title, ls for line style, and lw for line width, but what about lt and noti? (where can I look this up)?

With this, what do these last two lines do?

There are duplicates in the list. An alphabetically sorted list would be more helpful. – Joce Jul 20 at 16:54
    
@Joce Thanks for the spot. Take a moment to see the other answer where you can find a printable page with all the abbreviations sorted (and another not sorted): here the abbreviations are not alphabetically sorted because they come from the code as it is parsed, so that they result grouped in commands then in options relative to the each command (I know it misses the command but to parse all more than one level was over the extent of the answer). For example ti can be valid as title after a plot statement or as tics after the command set... – Hastur Jul 20 at 17:03

gnuplot has a set of commands and a set of options for each command. The name of each command and option can be abbreviated to the shortest unique string that describes it, e.g. p for the plot command, sp for the splot command, t for the title option to plot. Note that you can't, for example, use s for splot because it conflicts with set.

The two-letter abbreviations in gnuplot starting with l are usually for a line characteristic, like lt for linetype, lw for linewidth. These are actually unique flags which can be used interchangeably with the long form: lw, linew and linewidth specify the same option. You can see this in the command-line documentation for the set style line command:

help set style line

This gives

 Syntax:
       set style line <index> default
       set style line <index> {{linetype  | lt} <line_type> | <colorspec>}
                              {{linecolor | lc} <colorspec>}
                              {{linewidth | lw} <line_width>}
                              {{pointtype | pt} <point_type>}
                              {{pointsize | ps} <point_size>}
                              {{pointinterval | pi} <interval>}
                              {palette}
       unset style line
       show style line

and you can see that the options separated by a pipe ('|') are equivalent.

To be safe when starting with gnuplot, I recommend typing out the full commands, and when you get more experienced/lazy you can start abbreviating more.

[EDIT] to finish answering your questions:

1) lt stands for linetype. You can see what the line types are for the current terminal with the test command.

2) noti stands for notitle, which does what you think.

3) The last two lines draw f(1-g(x)) with no title and a 0.75pt wide red line; and f(12.5*g(x)) with no title and a 0.75pt gray line.

Here

gnuplot 5.0.3 List of Abbreviations

I think it is a useful resource and I followed my own suggestion (see below) :-). You can download the not sorted version too , where the abbreviation are not alphabetically sorted, and so are grouped in commands, and option relative to the commands.

Two ways

As far as I am aware there is not a complete list of abbreviations, at least it is not so simple to find it. Moreover it will be updated at each new version.

The assertion that gnuplot accepts the shorten unambiguous string for good is NOT TRUE.
I have to admit that it is a good rule of thumb to guess, but on which you cannot blindly rely: for example p is used for plot but it is ambiguous with print. So what to do?

  • Ask help to gnuplot itself
    In case of ambiguity you can ask for help to the CLI (command line interface) of gnuplot itself.

    gnuplot> help ti
    Ambiguous request 'ti'; possible matches:
           tics
           tikz
           time
           tips
           title
    
  • "If you want something doing, do it yourself!"
    Download from the gnuplot site the source code of your version.
    Extract the archive. Enter in the src directory and search for the tables.c file.
    Now your fortune depends from the tools you have on your system.
    It is a text file so you can read it with every word processor (but even notepad).
    Reading inside you will find a lot (e.g. 349 for the 5.0.3 version) of lines as the following:

    { "e$rrorbars", YERRORBARS }
    { "errorl$ines", YERRORLINES },
    { "eval$uate", eval_command },
    

    From the above you can understand that when you use e the CLI will understand errorbars, with errorl instead errorlines (here is the first unambiguous match different from the other just chosen) and so on...

    More down in the file you will find again an abbreviation for e

    { "e$rrorbars", YERRORBARS },
    

    but there is no ambiguity because it will be parsed not as command but as option of a command.

  • Ask a bash to work for you...

    If you are under Linux or a bash shell you can ask to your shell to work for you:

    grep '\$' tables.c  | sed 's/{//g ; s/}//g ; s/,//g ; s/"//g'
    

    that you can clean even more

    grep '\$' tables.c  | sed 's/{//g ; s/}//g ; s/,//g ; s/"//g' \
    | awk '{split ($1,a, "$"); printf ("%10s - %s \n", a[1],a[1]a[2] ) }'
    

    that gives those and other 345 lines...

         p - plot 
       rep - replot 
        sp - splot 
     multi - multiplot 
    

    still not perfect but, IMHO, acceptable.
