Code Files |
The input files used in this tutorial are provided in the code files link.
Please download and extract the file. |
| Slide Number 7
Download link |
Download links for texworks, Active Perl and Miktex are shown here. |
| Show screenshot of Desktop with graph.dat . | I have saved the input file data.txt on the Desktop. |
| Show screenshot of data.txt. | The file consists of 3 columns, x, y1, y2 type data. |
| Press Ctrl+Alt+T .
Type cd Desktop and press Enter. |
Please open a terminal and change the directory to Desktop.
I will write and save a script here using gedit text editor. |
| Type gedit gnuplot-tex.plt & and press Enter. | Enter the command as seen on the screen to make a script file.
Ampersand detaches the process from the terminal. |
| Cursor on gedit text editor. | Let's write the script to plot the 2 graphs on screen. |
| I will plot the 2 sets of data, y1 and y2, on y-axis. | |
| Type #interactive plot and press Enter. | First, I will write a comment line.
Let’s plot x-y1 data.
|
| Type, set terminal x11 and press Enter. | I will set the terminal. |
| Type, set boxwidth 1
set tics in set format y '%0.1e' set xtics set ytics set title "gnuplot and latex" and press Enter. |
I will add graph formatting commands and add a title for the plot. |
| Type,
set xlabel "$\\beta_u^2$ values" set ylabel "$\\sigma_y^2$" and press Enter. |
Here, we are incorporating latex symbols, beta and sigma in axis labels.
The underscore u, will format the u subscript in latex at a later stage. The carat 2 creates a superscript for the number two. |
| Type,
plot "data.txtgraph.dat" using 1:2 title 'Y1' and press Enter. |
Plot x y1 data and specify the legend as Y1. |
| Type
pause -1 “Press enter to continue” and press Enter. |
Next, type the pause -1 command line as seen on the screen.
The pause command suspends the script and waits for a user input. The -1 refers to the user input, which require the user to press the Enter key. The text press enter to continue is also displayed on the screen. |
| Type,
set ticslevel 0.5 set boxwidth 1 set format y '%0.2e' and press Enter. |
Next, we will plot x-y2 data.
|
| Type, set title "gnuplot-tex integration"
set xlabel "$\\beta_u^2$ values" set ylabel "$\\sigma_y^2$" and press Enter. |
I will again add few graph formatting commands.
I will also give a title and incorporate Latex symbols in axis labels. |
| Type, plot "data.txt" using 1:3 title 'Y2' with line
and press Enter. |
Make a plot with the first and the third columns here. |
| Type,
pause -1 “Press return to continue” and press Enter. |
Again, enter the command pause -1, with press return to continue at the prompt. |
| Press Ctrl+S and press Enter.
Type gnuplot and press Enter. |
I will save the file.
Minimize gedit and go back to the terminal. Open gnuplot from the terminal. |
| Press Ctrl + Shift + K. | I will also clear the screen. |
| Type, load 'gnuplot-tex.plt' and press Enter. | Let’s load the newly created script file as seen. |
| Hover mouse over the axis labels. | Notice the first plot has axis labels.
They are in Latex format, we will compile later on in this tutorial. |
| Press Enter in the terminal. | The terminal prompt reads, press enter to continue.
Press Enter in the terminal and notice the second plot. |
| Cursor on graphical window. | Now, I have seen both the plots.
I want to plot y1 and y2 together in a latex scaffold to generate a tex file. |
| Press Enter in the terminal. | Again, press Enter in the terminal.
Now we are back on gnuplot prompt. |
| Go to the gedit window. | Go to the gedit window to edit the script. |
| Type,
#latex file output and press Enter. |
Let's generate a tex file output from gnuplot.
I will add a comment line first mentioning the same. |
| Type,
set term latex set output "gnuplot.tex" and press Enter. |
Set the term to latex and give an output file name.
Here, the output filename is gnuplot dot tex. This generates a file in tex format. |
| Type,
set xlabel "$\\beta$" set ylabel "$\\sigma_y^2$" and press Enter. |
Here again, Latex symbols are incorporated in axis labels. |
| Type, plot "data.txt" using 1:2 title 'Y1' , "data.txt" using 1:3 title 'Y2' with linespoint lc 'blue' lw 2 pt 7 ps 1.5
and press Enter. |
I will change line, symbol and color properties in the plot command. |
| Type, pause 3 ‘Now tex file is generated’
and press Enter. |
For demonstration I will add 3 seconds delay after the pause.
The message text dipslay would read, Now tex file is generated. |
| Type reset and press Enter. | Type reset, to reset the terminal at the end of the script. |
| Press Ctrl+S and press Enter.
Type gnuplot and press Enter. |
Save the file.
Minimize gedit and go back to the terminal. |
| Type, load 'gnuplot-tex.plt' and press Enter. | Load the script file again. |
| Press Enter in the terminal. | Press Enter in the terminal and notice the second plot. |
| Press Enter in the terminal. | Press Enter again on the terminal, as seen here. |
| Text message Now text file is generated is displayed on the screen. | After the 3 seconds pause, the prompt returns to gnuplot prompt.
The output is a latex file as specified in the script. |
| Type q and press Enter. | Let’s exit gnuplot. |
| Go to Desktop. | Go to Desktop and notice the newly generated tex file. |
| Open the tex file. | Open the file using tex program.
Notice a large file in tex format. |
| Cursor on the tex file and scroll. | We will compile this file with tex and generate a pdf file output.
For this purpose, do the following. |
| Press Ctrl+N . | Open a new blank file from the tex window. |
| Type,
\documentclass{article} \usepackage{color} and press Enter. |
Enter the commands as seen on the screen.
We will add header and user package details. |
| Type,
\setlength{\textwidth}{100cm} \setlength{\textheight}{100cm} and press Enter. |
Pause the video as and when required. |
| Type,
\begin{document} \pagestyle{empty} \input{gnuplot.tex} \end{document} and press Enter. |
Next, compile the gnuplot generated file in latex.
Mention the name of the tex file that is to be compiled. Then, specify to end the document. |
| Press Control+S to save.
Give file name bgnuplot.tex, in Desktop folder. |
Let’s save the file.
I will give filename as bgnuplot dot tex and save in the Desktop folder. |
| Click on the typeset icon. | Now, click on the typeset icon or button to generate the pdf file.
A pdf file appears on the screen. |
| Hover mouse over Greek symbols, superscript and subscript. | Now, you have generated the graph integrating gnuplot and latex.
Notice the Greek symbols, superscript and subscript in the pdf file. |
| Close both tex documents and the pdf file. | Close the tex documents and the pdf file. |
| Go to the terminal. | Let's go back to the terminal.
Now, crop this document using the pdfcrop. |
| Press Ctrl+L. | I will also clear the screen. |
| Type pdfcrop bgnuplot.pdf and press Enter. | Enter the command, pdfcrop space bgnuplot dot pdf. |
| Cursor next to pdfcrop. | This program crops the margins from the pdf file.
The pdfcrop has named the file with a crop suffix. |
| Show screenshot accessing pdfcrop in windows. | The pdfcrop may look similar to this for Windows users. |
| Go to Desktop. | Go to Desktop again and notice the newly generated cropped file. |
| View the cropped file. | Open the cropped file to view it. |
| Close the cropped pdf file. | I will close this pdf file. |
