Hello First you should also reply to the gnuplot-info list gnuplot-infoWhile strings and pages of data seem cryptic, a plot reveals the entire data flow at a glance. Interpretation suddenly seems much easier. Understanding that maze of numbers requires just a glance. Scientists, mathematicians, engineers and statisticians rely heavily on plots. It is very popular amongst scientists and student communities.
The fact that GNUPlot can be used along with applications like Octave makes it even more indispensable. While the source code is copyrightedit can be freely distributed. GNUPlot supports many types of plots in 2D and 3D, and can draw using lines, points, boxes, contours, vector fields, surfaces, and various associated text, besides Web scripting.

Use this sample syntax to set the xtics:. Similarly, for the title of the graph, use the set title command as indicated below:. The default size of a Postscript plot is You can change the size with the set size width height command.
Rarely would you find a data set with only a single column of data. Let us consider a data set with three columns, with a blank space between columns, as shown below Data Set 1 :.
Copy the data set into an ASCII editor, hash the first line, and save it in your home directory as data1. To obtain the plot using Columns 1 and 2 and Columns 1 and 3, use the command below:. Experimental work always turns up errors — either instrumental, human or otherwise. The quality of work depends on the smallness of errors.
Here, we have used error bars parallel to the y axis. We could also use error bars in the x direction, with xerrorbars. Type in the following:.Today's Posts. Quick Links. Search Forums. Show Threads.

Basically its usage is common to those systems, so that this tutorial may be helpful for the other operating systems. First of all, exec gnuplot. Gnuplot is a command line driven plotting tool. You give commands here to make your figure. Actually there are more commands which cannot be categorized into the items above, so that it is hard to explain everything here.
See gnuplot online help by help command. Here we explain the simplest way to draw a graph with gnuplot. Once you quit gnuplot, all of setting you made will be lost. To save the current setting, use save command followed by a file name in which parameters and functions you defined are stored.
The file name is quoted by a single or double quotation. The file name is arbitrary, but if the same name exists in the current directory, gnuplot overwrites internal parameters in that file without any warnings. The saved file is a usual text file. You can edit the contents with a text editor.
To draw a graph again with this file, use the load "savefile. If you give the data-file name as a command line option the second casegnuplot ends after it reads the file, and you come back to shell. This is a batch mode. There are two basic commands to plot a graph, plot and splot. The former is used for a 2-dimensional graph, and the latter is for a 3-dim. Gnuplot makes a graph of any kinds of functions or numerical data stored in a file. You can omit the range parameters.
This is the 2-dimensional graph gnuplot generates. The frame is drawn by a thick line, which is called "border". The X and Y axes have graduation called "major tics", and numeric labels are written at the tics location.
Oh no! Some styles failed to load. 😵
The intervals between each major tic can be divided by minor tics. You can draw names of X and Y axes. The X-axis name -- "xlabel" -- is shown below the x-axis border, while the position of "ylabel" depends on your terminal. If your terminal can rotate letters, the degree rotated ylabel should go to the left of y-axis, otherwise it is shown at the top of y-axis.
If ranges of X and Y axes are not specified, gnuplot determines appropriate values for those automatically. To set the X range 0 to 5, . There are a number of parameters which change your plot appearance.
You can change them by the set command. See online help.
