Deprecated syntax

Gnuplot version 4 deprecated certain syntax used in earlier versions but provided a configuration option that allowed backward compatibility. Support for the old syntax has now been removed.

Deprecated in version 4 and removed in version 5:

     set title "Old" 0,-1
     set data linespoints
     plot 1 2 4               # horizontal line at y=1
Current equivalent:
     TITLE = "New"
     set title TITLE offset char 0, char -1
     set style data linespoints
     plot 1 linetype 2 pointtype 4
Deprecated but present in version 5 if configured -enable-backwards-compatibility
     if (defined(VARNAME)) ...
     set style increment user
     plot 'file' thru f(x)
     call 'script' 1.23 ABC 
        (in script:  print $0, "$1", "number of args = $#")
Current equivalent:
     if (exists("VARNAME")) ...
     set linetype
     plot 'file' using 1:(f(column(2)))
     call 'script' 1.23 "ABC"
        (in script:  print ARG1, ARG2, "number of args = ", ARGC
