Made some changes to the script embellishing a plot, but it still needs changes.
Plot with a specific color. Ex: RED :\\
{\ex \lstinline| plot(x, f(x), "r")|}
Plot with a specific style. Ex: DASHED :\\
{\ex \lstinline| plot(x, f(x), "--")|}
Plot with specific color and style. Ex: RED DASHED :\\
{\ex \lstinline| plot(x, f(x), "r--")|}
Plot with a specific line thickness:\\
{\ex \lstinline| plot(x, f(x), linewidth=3)|}
Adding title:\\
{\ex \lstinline| title("Plot of sin(x)")|}
labelling the axes:\\
{\ex \lstinline| xlabel("x")|}
{\ex \lstinline| ylabel("f(x)")|}
Adding annotations:\\
{\ex \lstinline| annotate("localmax", xy=(1, 2))|}
Using LaTeX typesetting on any text:\\
{\ex \lstinline| title("Plot of $sin(x)$")|}
Getting the axes limits:\\
{\ex \lstinline| xlim()|}
{\ex \lstinline| ylim()|}
Setting the axes limits:\\
{\ex \lstinline| xlim(x_min, x_max)|}
{\ex \lstinline| ylim(y_min, y_max)|}
