What is splot in Gnuplot?

What is splot in Gnuplot?

splot is the command for drawing 3D plots (well, actually projections on a 2D surface, but you knew that). It is the 3D equivalent of the plot command. splot provides only a single x, y, and z axis; there is no equivalent to the x2 and y2 secondary axes provided by plot.

What are Isosamples in gnuplot?

Isolines provide a simple means to display a surface. By fixing the u parameter of surface s(u,v), the iso-u lines of the form c(v) = s(u0,v) are produced, and by fixing the v parameter, the iso-v lines of the form c(u) = s(u,v0) are produced.

How use gnuplot data file?

To plot functions simply type: plot [function] at the gnuplot> prompt. Discrete data contained in a file can be displayed by specifying the name of the data file (enclosed in quotes) on the plot or splot command line. Data files should have the data arranged in columns of numbers.

Can the filledcurves style be used with Splot in 3D plots?

The filledcurves style is only available for 2d plots. But it can be used with some limitations with splot in 3d plots as well. In this entry we want to visualize an effect known from psychoacoustics, called comodulation masking release.

How to change the resolution of a gnuplot plot using text file?

The text file includes the longitude, latitude and three rgb color values. You have to invoke the script in the following way. where $RES is the desired resolution in pixel of your gnuplot plot and $FILE the input tif-file.
