how to create GIF animation in gnuplot | animation using gnuplot software

-

 GNUPLOT software is not only 2D and/or 3D plotting tool, but it also provides flexibility to create animation and GIF animation plots. 

GIF means Graphics Interchange Format. It is a repeated display of images from same of different sides.

It helps you to view the image clearly so that you don't need to pay much attention to understand it. 

This post provides you tools and techniques to create GIF animation in gnuplot.

Codes necessary for creating the GIF are given in links. Please check it as well.

GIF can also be both 2D and 3D.  You must use 'plot' command to create 2D GIF and 'splot' command to create 3D GIF.

Example of 2D GIF:



GNUPLOT code for creating above GIF, 👇

gnuplot > set title 'gif image of sine and cosine functions'

gnuplot > set xlabel 'x'

gnuplot > set ylabel 'sine and cosine'

gnuplot > f1(x,t) = sin(x-t)

gnuplot > f2(x,t) = cos(x-t)

gnuplot > set terminal gif animate delay 10 size 900, 800 

gnuplot > set output 'sinewave.gif' 

gnuplot > set xrange [-2*pi:2*pi]

gnuplot > set yrange [-1.5:1.5]

do for [i=1:96] {plot f1(x, i*0.1) title 'sin(x)', f2(x, i*0.1) title 'cos(x)'}
.................................................
To see the output, go to the FOLDER, where the newly created GIF 'sinewave.gif' is saved. Double click on this file and open it. If it does not open, then right on the file and follow the steps as follow:

sinewave.gif  -> right click -> open with -> google chrome or any other browser.

Example of 3D GIF:


Above GIF is a simple example of 3D GIF.
GNUPLOT Codes to create this GIF: 👇

gnuplot > unset border

gnuplot > unset ytics

gnuplot > unset xtics

gnuplot > unset ztics

gnuplot > unset key 

gnuplot > f1(x,t) = sin(x-t)

gnuplot > f2(y,t) = tan(y-t)

gnuplot > f3(x,t) = cos(x-t)

gnuplot > set xrange[-2*pi:2*pi]

gnuplot > set yrange[0:pi/2]

gnuplot > set terminal gif animate delay 10 size 900, 800

gnuplot > set output 'gif1.gif'

gnuplot > do for [i=1:96]{splot f1(x, i*0.1) lc 7 lw 3, f2(y, i*2.5) lc 10 lw 3, f3(x, i*0.1) lc 5 lw 3} 

Press ENTER  to get the GIF plot.

plot graph in gnuplot from csv and data file | knowledge of physics

-
 If you are using LINUX based OS, for example Ubuntu, you must be familiar with plotting data in gnuplot saved in a file with .dat extension. It is very simple technique.  To plot data in .dat format, you simply go to gnuplot and run following command, gnuplot> plot 'file_name.dat' using 1:2  This command gives you simple plot of your data saved in  file_name.dat. You can further modify this plot by adding title, axes names, legends and colors of plot and width etc. Here 1:2 means first column of data is along x-axis and second column along y-axis. But what about if you have data in a file of  .csv format ? Let's discuss. CSV means coma separated variables. This means each column of the data in the .csv file is separated by coma (,), and gnuplot does not accept this format directly just as you do for the .dat file.  For gnuplot to read data from .csv file, you should tell it that data you are applying are in coma separated format. So, write code as below...

projectile motion in fortran | relation of angle of projection and horizontal range

Image
 Have you ever tried to visualize projectile motion in fortran program? This post will help you to generate data and plot the graph of projectile motion.   Above figure shows you the angle of projection(°) versus horizontal range (meter) plot, where the speed of projection is 30 m/s. 👉 Click on link for NEB grade 12  physics numerical problem-solutions:-  LINK Let's start with some basic things: What is projectile and projectile motion ? Projectile:  A projectile is an object thrown to the sky with certain velocity against the earth's gravity. The motion that the projectile possesses during it's journey until it returns to the same surface, from where it was thrown, is called the projectile motion. In above figure, the projectile starts it's journey from point o and follows the curved path to reach another point on the same surface.  Suppose, `\theta` = angle of projection `\therefore` Angle of projection is the angle between the horizontal surface of ...

NEB physics exam numerical problems with solutions for grade 12 students

Image
 This post provides you the numerical problems and their solutions of physics based on NEB(National Examination Board) syllabus grade 12. Solutions of Previously Asked Numerical Problems in NEB exams. Q.1. A coil consisting of 100 circular loops with radius 0.60 cm carries a current of 5A. At what distance from the center, along the axis, the magnetic field has magnitude as `\frac{1}{8}` great as it is at the center? Solution:- Given, number of circular loops = N = 100 radius of the loop, `r = 0.60cm = 6.0 \times 10^-3` m. current, I = 5 A Magnetic field at the center of loop = B (suppose) magnetic field at distance x from the center = `\frac{1}{8}B`   To find, x = ? The magnetic field at distance x from center of the coil is given as, `B = \frac{\mu_o I N r^2}{2(x^2  + r^2)^(\frac{3}{2})}`. By given in question, magnetic field at x = `\frac{1}{8} \times` magnetic field at x = 0.       or, `\frac{\mu_o I N r^2}{2(x^2 + r^2)^(\frac{3}{2})} =\frac{1...

how to plot 3D and parametric graphs in gnuplot | three dimensional plot in gnuplot software

-
Image
Although being an open-source plotting software, gnuplot gives you almost all feasibilities to plot 2D, 3D, parametric plots and even the gif as well as animations.  Here you can learn to plot three dimensional graphs in gnuplot. Additionally, you also get the idea of parametric plots in gnuplot software. 1. 3D graphs in gnuplot To plot 3D graphs you just need to replace the command 'plot' for 2D graphs by 'splot' for 3D graphs.  Here, splot means surface plot.  Plotting graphs in 3D view allows you to observe it from all possible sides of the graph.  You rotate it upward, downward , left-side as well as to right-side.  Example: gnuplot >  splot sin(x) Then press ENTER key. You get the output as it looks as picture below: Fig. 1 3D graph of sin(x). 2. parametric plots Parametric plots can be created both in 2D and 3D.  For 2D graph, the dummy variable is t, whereas for 3D plot, they are u and v. Example: Image of parametric plot is shown below: Fig....

NEB board exam maths solved problems with proper solutions - available for free | short answered mathematics problems solved group A

-
Image
 This post provides you the problems with solutions of NEB board exam of grade 11 mathematics 2076. Attempt All Questions. Group A  `5 \times 3 \times 2 = 30` Get full question paper from Here . 1. a. Find the truth value of the biconditional statements of p and q where p represents '2 is an even number' and q represents '4 is an even number'. Solution:- Biconditional statements imply if one statement is true then another is also true. if one is false, then another statement is also false. So, one statement supports the other in case of biconditional statement.  Here, p: 2 is an even number.          q: 4 is an even number. 4 is the square of 2 and 2 is the square root of 4. 2 is even, then 4 is also even. So, both p and q represent true value (T). p q p ⇔ q T T T Thus truth value of p and q is T, i.e. 2 is an even number implies 4 is also an...
