• contour lines not showing up in new version 5.2 patch 7 or 8

    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.
