| Type '''gnuplot''' and press '''Enter''' to open '''gnuplot'''.

|-
|| Hover mouse next to '''term X11'''.
|| Notice, the terminal type is shown here as '''x11'''.
For some users '''qt''' or '''wxt terminal''' will be the default '''terminal'''.

|-
|| Cursor on the '''terminal'''.
|| '''Gnuplot''' supports several types of terminals.
Let’s open the details about terminal types using the help documentation.

|-
|| Press '''Control+Shift+K'''.
|| I will clear the screen.

|-
|| Type '''help set term''' and press '''Enter '''.
|| Enter the command '''help space set space term'''.

|-
|| Hover mouse over '''set terminal'''.
| The help documentation for the '''terminal''' opens.

|-
||
|| The '''set terminal''' command allows to set, the type of output to be generated.

|-
|| Hover mouse over '''set output'''.
|| This is commonly used together with '''set output''' command.
This directs the output to a file or a device.

|-
|| Hover mouse over '''Press return for more'''.
Press '''Enter'''.
Press '''Enter''' again.
|| The prompt reads as, '''Press return for more'''.
So, press '''Enter'''.
Press '''Enter''' again, till you notice the terminal list on the screen.

|-
|| Hover mouse on the terminals shown on the screen.
|| Nearly 40 types of terminals are supported by '''gnuplot'''.

|-
|| Hover mouse over '''x11, xterm'''.
|| For example, '''x11''' and '''xterm''' are interactive terminals.
They help to plot graphs on the screen.

|-
|| Hover mouse over '''postscript, pdf, svg'''.
|| '''Postscript''' and '''svg''' terminals direct output to a file in their respective formats.
The output can be saved and edited by the user.

|-
|| Point mouse to terminals available.
|| These aid the user in printing and sharing of graphs.

|-
||
|| Next, we will explore the options for '''postscript terminal'''.

|-
|| Hover mouse near '''subtopic'''.
|| The prompt is at '''subtopic of set term''' indicating the user to enter a '''subtopic'''.

|-
|| Cursor on the terminal.
|| Let's access help files for '''postscript''' file generation.

|-
|| Type '''postscript''' and press '''Enter'''.
| I will type '''postscript''' in the subtopic of set term prompt and press '''Enter'''.

|-
|| Hover mouse over syntax seen on screen.
|| Detailed syntax options for generating '''postscript''' file is shown on the screen.

|-
|| Hover mouse over '''landscape''' | '''portrait '''.
|| The orientation can be set to '''landscape''' or '''portrait'''.

|-
|| Hover mouse below on '''color, duplex''' and '''size'''.
|| Color, '''duplex''' option and size of the plot and other details can also be set here.

|-
|| Press '''Enter'''.
|| Press '''Enter''' as seen at the prompt.

|-
|| Show on screen help setting.
|| More details about the settings appear on the screen.

|-
||
|| You may pause the video and explore more about the command options.

|-
|| Press '''Ctrl+C '''.
|| I will press '''Ctrl C''' to exit the help details.

|-
|| Press '''Control+Shift+K'''
|| I will clear the '''terminal'''.

|-
|| Cursor on the '''terminal'''.
|| Next, let's make a '''postscript''' file for the '''sin x''' plot.

|-
|| Type '''plot sin(x)''' and press '''Enter'''.
|| Enter the command '''plot space sin x '''with x in parenthesis.

|-
|| Show the graph on the screen.
Close the graphics window.
|| '''Sin x versus x''' graph appears on the screen.
Close the graphics window.

|-
|| Go to the '''terminal'''.
| Go to the '''terminal'''.

|-
|| Type '''set term postscript landscape''' and press '''Enter '''.
|| Type '''set space term space postscript''' '''space landscape'''.
This sets a '''postscript''' capable '''terminal''' in '''landscape''' orientation.

|-
|| Type '''set output “sinx.ps”''' and press '''Enter'''.
| Next, type '''set space output space in double quotes sinx dot ps'''.
|-
|| Hover mouse next to the command.
|| This sets output in the user specified filename '''sinx dot ps'''.
|-
|| Type '''plot sin(x)''' and press '''Enter'''.
|| Enter command '''plot sin(x)''' to generate output to the file '''sinx.ps'''.
The output files are generated in the working directory.

|-
|| Press '''Control+Shift+K'''
|| I will clear the '''terminal'''.

|-
|| Type '''pwd''' and press '''Enter'''.
Hover mouse over the result.
|| Let's check the path of '''gnuplot'''.
Enter the command '''pwd'''.
The path shown here is '''Desktop''' directory.

|-
|| Go to '''Desktop''' and show the '''sinx.ps''' file.
|| Go to '''Desktop''' and notice the newly created file.

|-
|| Open '''sinx.ps''' file.
|| Double click on the icon to open and view the file.

|-
|| Close '''sinx.ps''' and go back to '''gnuplot'''.
|| We will close the output file and go back to '''gnuplot'''.

|-
|| Press '''Control+Shift+K '''.
|| I will clear the screen.
Let's save the output to a '''svg image''' file.

|-
|| Type '''set term svg background “cyan” size 400,400 '''
and press '''Enter'''.
|| For this, enter the command as shown here.
Type '''set space term space svg'''.
I will continue to add more specifications on the same line.

|-
|| Hover mouse on the command at '''background “cyan” size 400,400''' on the screen.
|| I will set a '''cyan''' background for the plot.
I will also define the output image pixel size to be '''400 by 400'''.

|-
|| Type '''set output “sinx.svg”''' and press '''Enter'''.
|| Now, specify a file name for the plot.
Type the following command.
'''set space output space in double quotes sinx dot svg'''.

|-
|| Type '''show palette colornames''' and press '''Enter'''.
|| The command, '''show palette colornames''' returns the color codes in '''gnuplot'''.

|-
|| Hover mouse over the 3 column output.
|| The output shows color name, corresponding '''hex code''' and the '''RGB code'''.
You may use this command to know more about color codes for different colors.

|-
|| Press '''Ctrl+Alt+K'''.
|| I will clear the screen.

|-
|| Type '''plot sin(x)''' and press '''Enter'''.
|| Enter the command, '''plot sin(x)''' to generate the '''svg''' image.

|-
|| Go to '''Desktop''' and show '''sinx.svg''' file icon.
|| Next, go to '''Desktop''' and notice the '''sinx.svg''' file that is generated.

|-
|| Double click to open the '''first.svg''' file.
|| Open the '''sinx.svg''' file.
View the square '''400''' by '''400''' '''pixel''' image of the graph.
The '''background''' has cyan color as specified.

|-
|| Close the image file and go back to '''gnuplot'''.
|| We will close the output file and go back to '''gnuplot'''.

|-
|| Type '''save term “svg.term” '''
and press '''Enter'''.
|| We can save the '''terminal''' setting for future use.
Type '''save''' space '''term''' space in double quotes '''svg dot term'''.

|-
|| Go to Desktop and show svg.term file icon.
|| Let us go to the '''Desktop''' and notice the newly created '''svg dot term''' file.

|-
|| Open svg.term file in text eidtor.
|| I will open it in a text editor.

|-
|| Show the opened '''svg.term''' file.
|| This file will have the details of the color and size as we entered.

|-
|| Close the image file and go back to '''gnuplot'''.
|| We will close the output file and go back to '''gnuplot'''.

|-
|| Type '''set term pop''' and press '''Enter'''.
|| To reset the terminal setting to the default state, type the following command.
Enter the command, '''set space term space pop'''.

|-
|| Curson in the terminal.
|| The reset command does not reset the '''terminal''' settings.

|-
|| Press '''Control+Shift+K'''.
|| Now, we are back on the interactive '''terminal'''.
I will clear the screen.

|-
|| Type '''plot sin(x) '''.
|| Enter the command '''plot space sinx''' with '''x''' in parenthesis.
Now, the plot is generated in the graphics window with the initial settings.

|-
|| Close graphics window.

ASCII output can also be generated in '''gnuplot'''.

|-
|| Type '''set term dumb''' and press '''Enter'''.
|| At the prompt, enter the command, '''set space term space dumb'''.
'''ASCII''' code is uniform across all operating systems.
Hence the files are portable across all operating systems.

|-
|| Enter command '''plot sin(x) '''.
|| Enter the command '''plot space sin x''', with '''x''' in parenthesis.
This prints '''ASCII''' text art output results.

|-
|| Show the '''ASCII''' output.
|| The output, is seen on the terminal screen.
