Will result in (gif mode) GNUPLOT - Graphic Data Analysis. Eric Thern Gnuplot is a function plotting program made for a command-line based system (Dos, Unix, linux, etc.).
It can run in multiple operating systems, and has many different plug-ins that offer a wide variety of data analysis. It can be used to plot functions and data points in both two- and three- dimensional plots in many different formats (GIF, LaTeX, etc.), and is an extremely wonderful tool for the graphical representation of data. Gnuplot is not part of GNU, but is distributed as part of the GNU package because it is a useful piece of software, and is free. Gnuplot can do all of the following: Plotting of two-dimensional functions and data points in many different styles (points, lines, error bars) plotting of three-dimensional data points and surfaces in many different styles (contour plot, mesh).
How to use Gnuplot, quickly and easily: This link will show some of the basics of Gnuplot. basics. Plot (3E) There are two methods to make a drawing which contains several figures. The first one is to use multiplot . The other way is to use the EPS format, then those files in this format are gathered by TeX or some drawing tools. Here we explain the multiplot command. With the command set multiplot you enter the multi-plot mode, and the gnuplot command prompt becomes multiplot> . In this mode a new figure overlaps the old one. Gnuplot> set multiplot multiplot> plot x multiplot> plot x*x multiplot> plot x*x*x multiplot> set nomultiplot Gnuplot determines the range, tics, and size of figure automatically for each plotting, then the plot gets into a mess.
Plot3d (1E) In the splot , the zero-point of Z-Axis is placed above the XY plane. To move this origin onto the XY plane, use set ticslevel . When ticslevel=0, the zero of Z-Axis moves to on the XY plane. gnuplot> set ticslevel 0 gnuplot> splot (x**2)*(y**2) In a 3-dimensional plot, mesh size (XY coordinate) is determined by isosample . The smaller this number, the more rough mesh you get. If the mesh is too rough, it sometimes makes trouble when a hidden line option set hidden3d is used. To avoid this problem, make isosample larger. Gnuplot> set isosample 40 The view point in the 3-dimensional plot is controlled by set view command.
Gnuplot> show view view is 60 rot_x, 30 rot_z, 1 scale, 1 scale_z Initially (before rotation), your screen is parallel to the X-Y plane and the Z-axis is perpendicular to that. Firstly, the X-axis is rotated to 60 degrees (rot_x), then the Z-axis slants. Next, the new Z-axis is rotated to 30 degrees (rot_z). The set view command rotates the graph. set view 60,30. Plot3d (1E) In the splot , the zero-point of Z-Axis is placed above the XY plane. To move this origin onto the XY plane, use set ticslevel . When ticslevel=0, the zero of Z-Axis moves to on the XY plane. Contours with gnuplot - Buscar con Google. Gnuplot how to obtain a contour profile. Gnuplot manpage 4.6 « Gnuplotting. Gnuplot homepage.
