Gnuplot error on command "set data s l"

Question

My program has gnuplot script and its first line is

set data s l

But this makes error

"cdia.GNUBAND", line 1: unrecognized option - see 'help set'.

I think it's the version problem and I have to change the "set data s l" command in right way. I searched on web but couldn't find it.. How do I solve this?

Answer 1

That is the shortcut for set data style lines, which is deprecated since version 4.0 (released in 2004). To replace this line, use

set style data lines

This sets the default plotting style for data set to lines, i.e. the commands

set style data lines
plot 'data.dat'

and

plot 'data.dat' with lines

are equivalent.
