So I had an old script that had the following in it:

set style data pm3d
set palette defined (0 "#663c5c", 1 "#ff96e8", 2 "black", 3 "#96a0ff", 4 "#3c4066")

set view equal xy
set view 60,30,1,1
set contour base
set cntrparam levels incremental 0.0,0.5,10.0

unset key
splot 'data.txt' u 1:2:3 t ""


It would plot the data as well as contour lines below. With newer versions of gnuplot, 5.2p7 or p8, it plots with no errors but is missing the contour lines. I'm looking at the help file but can't seem to see what I should change to get the contours back...help.

Thanks!
