Visual Cue Narration
Slide Number 1

Title Slide

Welcome to the tutorial on Example Scripts and Demo Folder.
Slide Number 2

Learning Objectives

In this tutorial, we will learn,
  • About gnuplot terminal and the graphics interface
  • About demo folder of gnuplot
  • About example script files
  • To load the script file to generate a graph
Slide Number 3

System and Software Requirement

To record this tutorial, I am using
  • Debian Linux 9.3
  • gnuplot 5.2.6
  • gedit text editor 3.22
  • Firefox web browser 52.5
  • Working Internet connection to access online script files
Slide Number 4

Pre-requisites

To follow this tutorial,

learner must be familiar with high school level Mathematics.

Slide Number 5

Extract gnuplot-5.2.6 folder

At the time of installation, we downloaded and extracted the gnuplot folder.

Generally, the folder gnuplot-5.2.6 would be in the Downloads folder.

Slide Number 6

Extract gnuplot-5.2.6 folder

If you had saved it elsewhere, then use that location for the next steps.
Slide Number 7

Missing gnuplot folder

What should you do in case the gnuplot folder is missing on your machine?

You have to follow the steps explained in the prerequisite tutorials in this series.

Open file manager, go to Downloads, gnuplot-5.2.6 and demo folder Open file manager.

Click on File Manager icon. In my machine, this icon is located on the menu bar at the bottom. Navigate to Downloads, gnuplot-5.2.6 and then to demo folder.

Scroll/highlight Notice the various files in the folder.
Press Ctrl+Alt+T keys We will now open a terminal by pressing Ctrl, Alt and T keys simultaneously.
cd Downloads/gnuplot-5.2.6/demo Type cd space Downloads slash gnuplot-5.2.6 slash demo and press Enter.

We are in the demo directory, which contains the example files.

Type ls and press enter Type ls to list the files in the demo directory.
Hover mouse over the .dem extension files Notice there are several files with dot dem extension.
Scroll up They are simple text scripts, which are used to generate plots.
Ctrl shift k on rdp machine Let me clear the screen.
Now let's look at the structure of demonstration an example script using a text editor.

I will use gedit text editor. You can use any other editor of your choice. Windows users may open the file in Notepad.

Type gedit simple.dem and press enter Type gedit space simple dot dem and press Enter.
The script file opens in the text editor window.
Hover mouse near required files in header.

Hover mouse next to the three functions in plot command

Details about this plot are mentioned in the header.

The required data files are also mentioned. This script plots three functions together.

Hover mouse next to left and right key in script Scroll down to view the entire file.

This is the structure of a script file.

Close gedit Now, close the text editor window.
Clear screen. I will clear the terminal.

Next, let's run this script in gnuplot and generate the plot.

>gnuplot

Press enter

In the terminal, type gnuplot and press Enter.
Hover mouse near gnuplot prompt The prompt changes to gnuplot prompt.

To execute a command in the terminal, press Enter after typing it. I will not mention this separately.

Ctrl shift k on rdp machine I will clear the terminal and bring the prompt back to the top of the terminal.
>load ''simple.dem'' To load the script, type load space within single quotes simple dot dem
Click on graphics window. A graphical window opens.

Click on this graphics window.

Hover mouse next to sin(x), atan(x) and cos(atan(x)) Three functions, sin x, atan x and cos atan x are plotted.
Scroll further in axis limits Using arrow keys, scroll, left, right, up and down within the plot.

Doing this allows us to scroll further in the axis limits. This feature is enabled in the script file.

Hover mouse next to “press enter to continue” and press enter simple dot dem can plot many graphs.

Go through the script file again, at this stage.

Go to terminal To see the next plot, go to the terminal by clicking on it.

We can read a message “Hit return to continue”.

Hit return Press the Enter key to continue.

From now on, you have to do this every time to get the next plot.

Show the change in graphics window Immediately, the next script and it's function gets plotted.
Press enter in terminal Press Enter again, as shown in the prompt to plot other functions from the script.
Show graphics window. Likewise, you can scroll through some more example files in the demo directory.
Close graphical window Now I will close this graphical window.
Press Ctrl + C Press Ctrl and C keys in the terminal, to come back to the gnuplot prompt.
Now, I will open a 3D plot demo example file.
load ‘hidden2.dem’ and enter Load the hidden2 dot dem file on the terminal.

Use the command as shown before to load the script file.

Show the graph A graphics window opens.
Go terminal press enter, view graph , repeat for 3 graphs Go through the 3 examples of the 3D plots this script can generate.
Close the graphics terminal. Then close the graphics window.
I encourage you to try other example files in this folder, likewise.
