[Gnuplot-info] howto do a surface plot with contour lines and dots for the original data points

[Lorenz <lor...@ya...>]

Hello all,

I'm trying to create a 3D surface plot with contour lines and overlay
it with dots denoting the original data points

what I've got so far is the following:

>set contour both
>set cntrparam levels incremental 0,10,100
>splot "data.text" u 1:2:3 w pm3d, "" u 1:2:3 w p pt 7

That's almost what I want, besides the that dots on the contour lines
(both on the contour lines themself and on there projection).


If I reduce the splot command to:

>set contour both
>set cntrparam levels incremental 0,10,100
>splot "data.text" u 1:2:3 w pm3d

I get the plot without any points. Adding the "w p" part adds the
lines both to the data points, as to the contourlines.

Using only the second part:

>set contour both
>set cntrparam levels incremental 0,10,100
>splot "data.text" u 1:2:3 w p pt 7

results in only (but all) the dots I get from the combined command.

So it looks like I need to "unset contour" between the two parts of
the splot command.
Is this possible? Or do I need a different approach altogether?
