If file names are given on the command line, gnuplot loads and executes each file in the order specified, and exits after the last file is pro- cessed. If no files are given, gnuplot prompts for interactive com- mands. I am new to gnuplot and having a hard time to figure how to do conditional plot. I have a data file, and I want to plot the data from 1st and 2nd columns to generate a line chart, save to JPEG/PNG file. test.txt. 1 9.9999 0 2 9.9999 0 3 9.9999 1 4 5.6000 0 5 3.4000 0 6 9.9999 1 To plot data in 2D we will make use of the plot command that we used for the functions. The general form of the plot command when printing a file is the following: This will answer your questions: from the Gnuplot manual, "The scale on y and the aspect ratio of the plot are both ignored." Thus, if one wants the circle to match the exact There are commands to change the terminal type, load files and specify the output device. Thus, one can view or print the images created by Gnuplot . If you have run Gnuplot, you should have a plot control file with a ``.plt'' extension. Suppose that this file was stem.plt. You can start up Gnuplot and issue the command gnuplot> load "stem.plt" gnuplot> plot 'mydata.dat' and a window should pop up displaying a graph of your data. axis intervals of a plot are too large, use the right mouse button to drag a zoom region in the plot, and a plot of your region of interest will be generated. Multicolumn Data If your data file contains several columns of data, specify the The following steps must be taken in order to create a plot using ns-3 's Gnuplot class: Modify your code so that is uses the Gnuplot class and its functions.

In this section, we describe some basic gnuplot commands that you will use over and over again. To learn more gnuplot commands or advanced options of the commands listed here, you should consult the Gnuplot Manual. plot plot is the primary command for drawing plots with gnuplot. It creates 2-D plots of functions and data Gnuplot is a command-driven interactive function plotting program. If files are given, gnuplot loads each file with the load command, in the order specified. Gnuplot exits after the last file is processed. Here are some of its features: Plots any number of functions, built up of C operators, C library functions, and some things C doesn't have Gnuplot is a command-driven interactive function plotting program.
