[Gnuplot-info] Splot (contour, view map) and plot on same graph

[Martin I. de O. <mar...@gm...>]

Hello,

I am trying to plot two graphs on the same plot.

The first is a simple x-y points plot:

plot myfile u 1:2

The second is a contour plot at level 0, which I can plot with the
following commands:

set contour
unset surface
set map view
set cntrparam levels discrete 0
splot a*y**3 + b(x)*y**2 + c(x)*y + d(x)

b(x), c(x) and d(x) are known polynomial functions on x.

Both use the same xrange and yrange.

How can I plot them both in the same graph?

Thank you,
Martin
