Gnuplotis a free, command-driven, interactive, function and data plotting program. Pre-compiled executeablesand source code for Gnuplot 4.2.4 may be downloaded for OS X,Windows,OS2, DOS, andLinux. The enhancements provided by version 4.2 are described here.
Gnuplot is a free plotting tool thatcan be run from the command-line or invoked by third-party applications. Despiteits name, the program is not related to the GNU project. The plotting commandsand the input data are read from files or stdin. The development ofGnuplot started already in 1986.
Instead of transfering the output data to Gnuplot by file, we can feedplotting options and data values directly by connecting both applications withUnix pipes. Theoutput of the Fortran program will become the input of Gnuplot.
Or, run echo \"set term\" gnuplot in the terminal. The backendssixelgd and sixeltek require a Sixel-compatibleterminal, such as xterm(1) or mlterm(1) on Unix(table 1). Terminal emulators that do not support the format will ignoreany Sixel data. XTerm has to be run in VT340 mode to enable Sixel graphics:
gnuplot is a portable command-line driven interactive datafile (text or binary) and function plotting utility for UNIX, IBM OS/2, MS Windows, DOS, Apple Mac, VMS, Atari and many other platforms. The software is copyrighted but freely distributed (i.e., you don't have to pay for it). It was originally intended as graphical program which would allow scientists and students to visualize mathematical functions and data. It does this job pretty well, and in addition it serves as non-interactive plotting engine for miscellaneous portable third-party applications, like Octave. Gnuplot is developed and supported since 1986, and having its scripts and commands easy to understand text files, it is time-portable as well.
Gnuplot is a command-driven interactive function plotting program. It can plot functions and data points in both two- and three-dimensional plots in various formats (points, lines, surfaces, contours). A set of built-in terminal drivers support many different graphics devices, eg. for plotting to different types of terminals or for generating GIF, postscript, latex files.
At the time of this writing, there are two supported client programmes available to display Cactus ASCII output graphically, namely xgraph and gnuplot. Although xgraph is the default output format, gnuplot offers many more features to the intermediate and expert user. Among those are the capability to choose which part(s) of the dataset to display, or to combine with other data. Below you find an introduction to creating and viewing Cactus ASCII output files in the gnuplot format. Step by step you are then introduced to more advanced features of gnuplot.
By default, 1D ASCII output from the released Cactus thorns uses xgraph format, and most of the example parameter files distributed with thorns follow this convention. The parameter file wavetoyc_gnuplot.par in thorn WaveToyC in the CactusWave arrangement produces gnuplot output, demonstrating all released output methods which can produce gnuplot output. To test this out:
You can not only display files, but arbitrary output produced by other programmes. This is especially helpful to preprocess data files through scripts, e. g. using paste, awk, or perl. For reasons of space I will not describe using awk or perl here.
Gnuplot (together with the various scripting languages) is a very powerful tool. You can produce reasonable graphs with just a few commands, but there are many more than shown here in this introduction. The ability to write programmes and execute them later makes it easy to repeat previous work, should, hypothetically, any data files change just hours prior to a deadline. It also makes it less tedious to produce many similar graphs.
We need to download some data files. We can do that, and add another line to the gnuplot script. The escaping on the quotes and commas is especially tedious in this one ;) but, we don't need those pesky line-continuations here.
The macro above will do the grunt work on each form in the gnuplot macro. Finally, for the gnuplot macro, I want to take all the forms, convert them to gnuplot commands, write them to a temporary file, and then run gnuplot on the file, and finally delete the temp file. I assume we start with a gui terminal so graphs pop up unless you change it in your macro body. Here is that macro. It returns the generated code so it easy to see if you got the right program.
We often write code in supporting information files that generates figures or tables in a scientific manuscript. Today, we explore how to call those code blocks remotely but get the output in the file we call it from. We will write code in si.org that generates an interactive figure that is presented in this file. We will use data published in hallenbeck-2015-compar-co2. You can find the data we used in the SI for that paper, or more conveniently here .
Continuing the exploration of interactive figures, today we consider the Python plotting library mpld3 . We will again use our own published data. We wrote this great paper on core level shifts (CLS) in Cu-Pd alloys boes-2015-core-cu. I want an interactive figure that shows the name of the calculation on each point as a tooltip. This data is all stored in the supporting information file, and you can see how we use it here. This figure shows how the core level shift of a Cu atom changes depending on the number of nearest neighbor Cu atoms. Just hover your mouse over a point to see the name and CLS for that point.
We will get the data from our paper on coverage dependent adsorption energies xu-2014-probin-cover. There are some data rich figures there that would benefit from some interactivity. You can get the data here: . Extract out the supporting-information.org and energies.json file to follow here. We will make Figure 2a in the SI document here, and make it interactive with hover tooltips.
Gnuplot is a command-line-driven program. As such,it has been co-opted to provide graphic capabilities in several otherapplications, such as octave. Thus, you may have used gnuplot without evenrealizing you were doing so. You can use gnuplot in several ways. It not only can accept input data to plot, but it also canplot functions. Gnuplot can send its output either to the screen(in both a static file format display or an interactive display), orit can send output to any of a large number of file formats. Additionally, lots of functions are available to customize your plots, changing thelabels and axes, among other things.
This is fine if you are just trying to see what some expression looks likewhen it is plotted out, but in real science, you often collect data inexperiments that need to be plotted so you can do some graphicalanalysis and get ideas as to what may be happening. Gnuplot canhandle this type of plotting too. To do so, you simply need to hand inthe filename of the file containing the data to be plotted. This fileshould have the data elements arranged in columns, where the columns areseparated by white space of some kind. Any lines that start with #are treated as comments by gnuplot and are ignored. If your data filecontains several data columns, you can select which columns are pulled into be plotted as options to the plot or splot functions. As an example,say you have a data file that has the temperature and pressurefor each day. You can plot the temperature with:
Gnuplot is a program for creating plots, charts, and graphs thatruns on Linux as well as on a wide variety of free and proprietary operating systems.The purpose of a plot, in general, is to help to understand data orfunctional relationships by representing them visually. Some plotting programs, including gnuplot, may perform calculations and massage data,which can also be convenient.
Having the right packages installed before compiling gnuplot will ensure that the resulting binary supports the \"terminals\" that you want to use. In gnuplot land, a terminal is the form taken by the output: either a file on disk or a (possibly interactive) display on the screen. Gnuplot is famous for the long list of output formats that it supports. You can create graphs using ASCII art on the console, in a canvas on a web page, in various ways for LaTeX and ConTeXt, as a rotatable, zoomable object in an X window, for Tektronix terminals, for pen plotters, and much else, including Postscript, EPS, PNG, SVG, and PDF.
Gnuplot comes withextensive help. For extra information about any of the commands used below, try typing\"help command\" at the gnuplot interactive prompt. For more, try theofficial documentation [PDF], the many examples on the web,or the two books about gnuplot:one by Philipp K. Janert and one by me. The command stanzas here can be entered as shown at the gnuplot prompt or saved ina file and executed with: gnuplot file.
Gnuplot and LaTeX share a family resemblance. They are both earlyopen-source programs that demand a certain amount of effort on the part of the userto achieve the desiredresults, but that repay that effort handsomely. They're both popularwith scientists and other authors of technical publications. Both programsare unusually extensively documented by both their creators and a cadreof third parties. And both systems, originating in an era of more anemichardware, do a great deal with a modest amount of machine memory. Gnuplot has a good reputation for the ability to plot large data filesthat cause most other plotting programs to crash or exhaust the availableRAM. 153554b96e
