Gnuplot is a free, command-driven, interactive, function and data plotting .. eine Einführung (in German): Windows from Mac .. Note: if you use German language settings in your shell, you. This section provides an overview of what gnuplot is, and why a developer might want to use it. It should also mention any large subjects within gnuplot, and link.

Official gnuplot documentation

The current public version of gnuplot is Gnuplot It deeutsch greek letters, super- gnuplott sub-scripts in postscript output. See “help postscript” for detail. The figure below is a sample output of gnuplot4. The horizontal axis is the type of points, and the vertical axis is the type of lines. The script file is hereand its output EPS file is here. Line and point color is specified by the linetype.

The above number-color correspondence in gnuplot But the “linestyle” in 3. Then the figure is saved in the PS file which you specified. Guide is here ps or here pdf.

The first one is 3-d plot, and the second one is a naive way of tutoroal multi-figures in one plot. Example of 3D plot.

Energy Surface of 12 C, taken from our paper. By using “splot”, we can draw surface and contours.

Drawing contour in 2D plot is not a trivial task When we try to draw 2D contour by using “set view 0,0” as in this scripty-axis is drawn in the right axis, and the contour line type cannot be specified, as in the left figure. Thus I usually do this in two steps. In the first step, I output the contour data in “tables”, and in the second step, I plot that data.

This enables us to plot some figures in one plot, if you are patient.

You can also use “set multiplot”, when the figures are not connected. In recent versions of gnuplot, we can set bmargin bottom margintmargin, lmargin, and rmargin in plot and multiplot.

It means that, without any functional transform, drawing axis by hand, or fine tuning of the position of figures in multiplot, we can draw compactly packed figures. It is also possible to use “multiplot layout”, but I think it is not yet in a satisfactory level. We can fill the area surrounded by your curve. You can draw a filled big circle in the following way, set size ratio 1 set parametric set tra [0: It may be a good idea to re-draw the curves twice.


I show the figure of prediced pressures and experimentally suggested area taken from our paper.

In this figure, since we want to show the keys seutsch theories before data key, we draw the theoretical lines twice before and after “filledcu” plot. Folloing two figures are also drawn with gnuplot.

I will explain later some time
