[Gnuplot-info] Can one save and retrieve contours in splot?

[David K. <da...@gn...>]

Because of the current epslatex terminal's inability to draw dashed line
patterns in contours, I am in trouble.

Issue 1612 would indicate that temporarily saving contours to data may
help, but that apparently is only feasible when using the data with plot
(and thus a rectangular projection) rather than splot: for the following
fragment

set table $blobs
splot [-pi:pi][-3:3] 2*pi*Vm0m1(1,-1,0,pi/4,x,y) title "$2\\pi V_{1,-1}^{(0,\\pi/4)}(\\theta,p)$" nosurface
unset table
splot [-pi:pi][-3:3] 2*pi*Vm0m1(1,-1,0,pi/4,x,y) title "$2\\pi V_{1,-1}^{(0,\\pi/4)}(\\theta,p)$" nocontours, $blobs nosurface

I get

splot [-pi:pi][-3:3] 2*pi*Vm0m1(1,-1,0,pi/4,x,y) title "$2\\pi V_{1,-1}^{(0,\\pi/4)}(\\theta,p)$" nocontours, $blobs nosurface
                                                                                                               ^
"wigner4.gp", line 190: 2 columns only possible with explicit pm3d style (line 8)

Is there any expedient for reattaching exported contours into a full
splot command, allowing me to root around the current dash pattern
initialization bug?
