GNUPLOT is a command line tool to generate 2D and 3D graphs. Lets write a small program to create a graph as shown below using C / C++ program with gnuplot tool.
gnuplot.gnuplotPath: Path to the Gnuplot executable. Not used by this extension directly, but useful in tasks.json if it's checked into repositories. Use a command such as $ {config:gnuplot.gnuplotPath}.
To make use of the problem matcher, the task should pass the relative file path to Gnuplot. Example task in tasks.json: { "label": "Plot with Gnuplot", "command": "$ {config:gnuplot.gnuplotPath}", "args": [ "$ {relativeFile}" ], "problemMatcher": "$gnuplot" // ...

type “sudo apt-get install gnuplot" and Gnuplot will install. Now you should be in the Gnuplot environment which, like the Terminal, is com- mand line based. From here we are ready to plot to a file. Basic plotting from a file is straight forward.
Learn step-by-stepPlot a simple data set to understand the basic setup for gnuplot.Plot data sets with error bars.Perform operations on data sets and plot continuous functions.Perform operations in bash script.Fit functions and automatize the analysis process of a large number of data sets.
gnuplot is a not-quite-as-easy-to use, though extremely powerful, command-line plotting program. Running gnuplot is easy: from a command prompt on any system, type gnuplot. It is even possible to do this over a telnet or ssh connection, and preview the graphs in text mode!
C and Gnuplot can be used to plot complex functions. One can write the function in C and then write the values of the function at various values in a txt file, which can then be plotted using Gnuplot. The txt file should have numerical values in at least two columns. The first column is for x values.
There is also a graphical user interface (GUI) for gnuplot . It is called qgfe .
Installing Gnuplot on WindowsChoose the download for gnuplot 4.2. ... Download the file gp424win32.zip.Create a folder named gnuplot directly under C:\extract all of the zip file into that folder.Use Explorer to go to C:\gnuplot, and find the bin subdirectory. ... Create a desktop shortcut to this executable.
The Gnuplot history dates back to 1986. Current stable version of gnuplot is 5.2 released in Aug. 2017. Current development version of gnuplot is 5.5.
Introduction. Matplotlib is a plotting library like GNUplot. The main advantage towards GNUplot is the fact that Matplotlib is a Python module.
You can run a script two ways: Type load "scriptname" from within gnuplot. Or, from UNIX, run gnuplot by typing gnuplot scriptname . In this method, gnuplot will exit when your script is finished, so you may want to include PAUSE -1 "Hit any key to continue" as your last line.
Following steps were followed:Define the x-axis and corresponding y-axis values as lists.Plot them on canvas using . plot() function.Give a name to x-axis and y-axis using . xlabel() and . ylabel() functions.Give a title to your plot using . title() function.Finally, to view your plot, we use . show() function.
Gnuplot is a portable command-line driven graphing utility for many platforms. To leverage the powful gnuplot to plot beautiful image in efficicent way in python, we port gnuplot to python. Let's see an example at first: #!/usr/bin/env python3 #coding=utf8 from pygnuplot import gnuplot g = gnuplot.

gnuplot is a command-driven interactive function plotting program. It can be used to plot functions and data points in both two- and three- dimensional plots in many different formats. It is designed primarily for the visual display of scientific data.

At first something that really bothered me in C++ was this STDs everywhere.
I was learning about modules, and I tried writing some code with it, which is as follows:
hey guys, i have a basic knowledge of how things in c++ work (till c++11) but don't have what it takes to implement them. My main motive is finding bugs (memory corruption, logic , race etc) in c++ programs.
gnuplot is a powerful plotting program that can be utilized to display plots and save them as files. It is generally used with file data sets with the simple column-based format where each column is delimited with a single space, as shown below.
Alternatively, we can stream the previously stored data in a separate file directly from the program memory. The popen function is used again to open a pipe communication to the gnuplot program and then send the numbers stored in arrays with special formatting.
