Code Examples

Example 1: Simple 2D Plot

​​\documentclass{article}
\usepackage{pgfplots}
\begin{document}

\begin{tikzpicture}
    \begin{axis}[
      axis lines = middle,
        xlabel = $x$,
        ylabel = {$f(x)$},
    ]
    \addplot[samples=100, domain=-2:2, blue, thick] {x^2};
    \end{axis}
\end{tikzpicture}
\end{document}

Explanation of the code:

Output: This creates a simple parabola f(x) = x^2 with labeled axes. 2D PLOT

Example 2: 3D Surface Plot

\documentclass{article}
\usepackage{pgfplots}
\begin{document}

\begin{tikzpicture}
    \begin{axis}[
        view={60}{30},
        axis lines = middle,
        xlabel = $x$,
        ylabel = $y$,
        zlabel = {$f(x,y)$}
    ]
    \addplot3[surf, domain=-2:2, y domain=-2:2] {x^2 + y^2}; 
    \end{axis}
\end{tikzpicture}

\end{document}

Explanation of the code:

Output: This generates a 3D surface plot for f(x,y)=x^2+y^2
