Problem with linespoints style in 3D plotting

[Mohammad]

Sample code

$xyz << EOD
# X   Y    Z
0   0    0
0   1    1
0   2    4
0   3    9
0   4   16
0   5   25

1   0    1
1   1    2
1   2    5
1   3   10
1   4   17
1   5   26

2   0    4
2   1    5
2   2    8
2   3   13
2   4   20
2   5   29

3   0    9
3   1   10
3   2   13
3   3   18
3   4   25
3   5   34
EOD

#
# create the contour lines
set contour base
set cntrparam level incremental -3, 0.5, 3
unset surface
unset key

set style data linespoints

set table $xyz_contour
splot $xyz
unset table
plot $xyz_contour 

Problem
In the above code if you remove the line

set style data linespoints

The gnuplot works but with the above line the following error raised and an empty graph is shown

Error:

Tabular output of this 3D plot style not implemented

Is there any conflict with these settings? If you even use style lines, gnuplot still works!

The error message is correct. Gnuplot's tabulation mode ("set table")
does not handle all possible
gnuplot plot styles. In particular it does not handle "with linespoints"
for 3D plots.
