#Gnuplot surface plot how to

3 It is a program with a fairly long history, dating back to 1986. The program runs on all major computers and operating systems ( Linux, Unix, Microsoft Windows, macOS, FreeDOS, and many others). It is the 3D equivalent of the plot command.

Create a contour plot by looking straight down onto the coordinate plane and using contour lines (similar to the ones found on topographic maps) to indicate the elevation (or whatever the dependent variable represents). gnuplot is a command-line and GUI program that can generate two- and three-dimensional plots of functions, data, and data fits. splot is the command for drawing 3D plots (well, actually projections on a 2D surface, but you knew that).

Create a rendering of a raised surface.In gnuplot, you have essentially the same options cartographers have:

Its syntax is very similar to the syntax for the plot command. But what if you want to show how some quantity depends on two independent variables? In other words, how can you best visualize a single “output” variable as a function of two “input” variables? That’s basically the problem cartographers have: show a quantity (the elevation above sea level or the type of ground cover) as a function of two coordinates (the position on the surface). Surface plots (and contour plots) are created using the splot command. The plot command discussed in this book creates graphs that show how one variable ( y) behaves as a function of another one ( x).
