It has two mandatory inputs: the minimum and maximum of the axis, so, the full instruction is: \Verb*|\nlAxisX{min}{max}|: + + + \begin{Verbatim}[gobble=1,xleftmargin=5mm] + \begin{tikzpicture} + \nlAxisX{-2}{5} + \end{tikzpicture} + \end{Verbatim} + + + would give the output: + + \medskip + + \begin{center} + \begin{tikzpicture} + \nlAxisX{-2}{5} + \end{tikzpicture} + \end{center} + + + After the axis is drawn, one can start placing the intervals. To do this we will consider two kinds of intervals, the ones with infinity, either \(-\infty\) or \(+\infty\) and the ones with two numbers. + + \newpage + + + Let's start with the first group. + + \begin{itemize} + \item \verb*|\nlinfnum| will draw intervals of the kind: \(\left]-\infty, number\right]\) or \(\left]-\infty, number\right[\). + \item \verb*|\nlnuminf| will draw intervals of the kind: \(\left[number, +\infty\right[\) or \(\left]number, +\infty\right[\). + \end{itemize} + + These two commands also have two mandatory inputs: first one is the number ({\it always a decimal representation, so, something like \(\pi\) doesn't work but there is a workaround!}) and the second if it's an \underline{o}pen or \underline{c}losed interval at the number. So, for instance + + \medskip + + \begin{Verbatim}[gobble=1,xleftmargin=5mm] + \begin{tikzpicture} + \nlAxisX{-2}{5} + \nlnuminf{3}{o} + \nlinfnum{1}{c} + \end{tikzpicture} + \end{Verbatim} + + gives us + + \medskip + + + \begin{center} + \begin{tikzpicture} + \nlAxisX{-2}{5} + \nlnuminf{3}{o} + \nlinfnum{1}{c} + \end{tikzpicture} + \end{center} + + This time, there are a few optional inputs, the full commands are like this: + + \begin{Verbatim}[gobble=1,xleftmargin=5mm] + \nlnuminf[1]{number}[2]{o or c}[3] + \nlinfnum[1]{number}[2]{o or c}[3] + \end{Verbatim} + + \begin{itemize} + \item in [1] you can put options like different colours or patters used; + \item in [2] you can substitute the number for a letter or an exact representation of the number, don't put it in math environment!; + \item in [3] you can change the height of the interval, which is \(0.5\si{\centi\meter}\) by default. + \end{itemize} + + + Let's try some of these options: + + \begin{Verbatim}[gobble=1,xleftmargin=5mm] + \begin{tikzpicture} + \nlAxisX{-2}{5} + \nlnuminf[pattern=north west lines]{1.4142}[\sqrt{2}]{c}[.7] + \nlinfnum[red!20]{3.1416}[\pi]{o} + \end{tikzpicture} + \end{Verbatim} + + + \begin{center} + \begin{tikzpicture} + \nlAxisX{-1}{4} + \nlnuminf[pattern=north west lines]{1.4142}[\sqrt{2}]{c}[.7] + \nlinfnum[red!20]{3.1416}[\pi]{o} + \end{tikzpicture} + \end{center} + + +\newpage + +The second group of intervals, works with a single command: + +\begin{itemize} + \item \verb*|\nlnumnum| +\end{itemize} + +and, since it uses two numbers, we have four mandatory inputs: the numbers and the instruction of closed or open. It works like this: + + +\begin{Verbatim}[gobble=1,xleftmargin=5mm] + \begin{tikzpicture} + \nlAxisX{-2}{5} + \nlnumnum{-1}{o}{3}{c} + \end{tikzpicture} +\end{Verbatim} + + \begin{center} + \begin{tikzpicture} + \nlAxisX{-2}{5} + \nlnumnum{-1}{o}{3}{c} + \end{tikzpicture} + \end{center} + +As with the previous commands, there are a few options, this time we have one more which allows us to change what is shown in the second number: + + +\begin{Verbatim}[gobble=1,xleftmargin=5mm] + \begin{tikzpicture} + \nlAxisX{-2}{5} + \nlnumnum[red!20]{-1.4142}[-\sqrt{2}]{o}{3.1416}[\pi]{c} + \end{tikzpicture} +\end{Verbatim} + + +\begin{center} + \begin{tikzpicture} + \nlAxisX{-2}{5} + \nlnumnum[red!20]{-1.4142}[-\sqrt{2}]{o}{3.1416}[\pi]{c} +\end{tikzpicture} +\end{center} + + +\section{Conclusion} + +This is a really simple package (my first attempt at a package) but one that, I hope, can help you draw stuff like: + +\begin{center} + \begin{tikzpicture} + \nlAxisX{-2}{5} + \nlnumnum[red!20]{-1.4142}[-\sqrt{2}]{o}{3.1416}[\pi]{c} + \nlnuminf[pattern=north west lines]{1.4142}[\sqrt{2}]{c}[.7] + \nlinfnum{2}{o}[.3] + \end{tikzpicture} +\end{center} + +somewhat quickly and easily.
