✅ Step-by-Step Guide:

1. Install Gnuplot:
Open your terminal and run:

sudo apt update
sudo apt install gnuplot

2. Launch Gnuplot:
Start the interactive environment by typing:

gnuplot
You should see a prompt like gnuplot.

3. Basic 2D Plotting:

-Simple 2D Function Plot:

plot sin(x) with lines

▪ This will plot the sine function.

-Customized 2D Plot:

set title "My First 2D Plot"
set xlabel "X-axis"
set ylabel "Y-axis"
plot sin(x) with lines title "Sine", cos(x) with lines title "Cosine"

-Legend Box:
Legend is a box in the corner that shows which line is for which function
▪ Add titles to show in legend: title "Your Label"
▪ Remove legend completely: unset key

plot sin(x) title "Sine Wave", cos(x) title "Cosine Wave"

4. Basic 3D Plotting:

-Simple 3D Function Plot:

set title "3D Surface Plot"
splot sin(x)*cos(y) with pm3d

-Customized 3D Plot:

set title "3D Function"
set xlabel "X"
set ylabel "Y"
set zlabel "Z"
set isosamples 50
splot x**2 + y**2 with pm3d

5. Plotting from Data Files:

1) Create a data file data.txt:

1 2
3 4
5 6
7 8

2) Plot it in gnuplot:

plot "data.txt" with linespoints

6. Saving Your Plots:
To save any plot as an image:

set terminal png
set output "plot.png"
replot
set terminal wxt

7. Exiting Gnuplot:
Type:
exit

✅ Quick Reference:
• plot f(x): Plot 2D function
• splot f(x,y): Plot 3D function
• with lines: Connect points with lines
• with points: Show data points
• title "Name": Add legend entry
• set xlabel "Text": Label x-axis
• set title "Text": Add plot title
• set grid: Add grid lines
• unset key: Disables the legend


✅ Why Use Gnuplot?
• Versatility: Plot a wide range of 2D and 3D graphs.
• Customization: Fine-tune every aspect of your plots.
• Free & Open-Source: No cost, ever!


✅ Pro Tips:
• Experiment with Commands: Try different functions and data sets.
• Save Scripts: Write Gnuplot scripts for reproducibility.
• Explore Documentation: Learn more advanced features from the Gnuplot manual.
