Building 3D Data with Gnuplot

Question

My 3D data is stored in a TXT file as follows

3423.432 4353.23 45345.435 324.4 4352.2 3342.3 1234.3 3988.4 342. ... 

therefore, each column corresponds to a separate axis (x, y, z). How could I plot the data in 3D with Gnuplot so that the x, y, and z axes are shown for orientation?

Answer 1

See the Pseudo 3D Bar graph section in this article. You are about to use the splot command, specially created for 3D graphics. The article provides simple examples that match what you are looking for. The data in the format that you already have, "XYZ" is also good, so you do not need to configure anything.
