The image can also be projected on a 3D figure of the world as shown in Fig. GNUPLOT contour over splot with pm3d from different data files.
Gnuplot lets you show contour maps, but you can't draw 2d points and lines on them. GNUPLOT contour over splot with pm3d from different data files. Gnuplot has strong support for creating three dimensional plots for functions and for properly formatted data files.
Another possibility is to use directly splot ... with pm3d instead of plot ... with image, but this could be undesirable if you use a vector-based terminal because of the file sizes. For contour options, try help set cntrparam. my script::: ~~~ Set terminal and output. The reason behind this is that in a 3D plot, we have to have some space for the z axis, and even if we drop it in the map view, the space-holder for the z axis is still there, therefore, gnuplot makes the whole plot a bit smaller. I need to plot a pm3d colour map, for the two variable function z=z(x,y) available in the form of discrete z values on a regular x-y grid.
set terminal postscript enhanced color set output 'plot.ps' . Plotting the map appears relatively easy, but it would be nice to have simultaneously contour lines on the plot, together gnuplot,contour. Perhaps there is no blank line in between two subsequent scans (isolines) in the data file?

You do set pm3d; splot ’a.dat’ and no plot but colorbox appears. Related: Gnuplot: Fitting asymptotic curve to data gnuplot I am
I want to plot two contours and a plot with datapoints on top of eachother.

Contour maps are very useful to make it easier to see the peaks and valleys, and see what areas have the same range of values. Gnuplot has strong support for creating three dimensional plots for functions and for properly formatted data files. i am struggling in trying to splot a nonuniform binary matrix from a datafile1, and plot over it a contour of another variable, over the same grid but another datafile. unset hidden3d # draw the surface using pm3d's hidden3d with line type 100 unset hidden unset surface set title "set pm3d hidden3d

Since my suggestion is a bit too long for a comment: Have you tried plotting both original files together? In gnuplot's case, 'properly formatted' means that the data is not arranged as sets of z values with their corresponding x and y values, but as z values whose x and y values are indicated by their relative position (the Gnuplot documentation calls this 'grid' format).
