# I cannot plot this negative graph for some reason on Latex

I am trying to plot the equation -\frac{7}{6}\frac{1}{16\pi^2}x^3 but I keep getting the error, missing number treating as zero. I have no idea what is going on because I am a newbie at this.

• Welcome to TeX-SE! As long as you do not show us what you have tried one cannot really tell you what went wrong. For me the following works: \documentclass[tikz,border=3.14mm]{standalone} \usepackage{pgfplots} \pgfplotsset{compat=1.16} \begin{document} \begin{tikzpicture} \begin{axis} \addplot[mark=none] {(7/(6*16*pi^2))*x^3}; \end{axis} \end{tikzpicture} \end{document} – marmot May 18 at 15:29

• Yeah I deleted the code out of frustration. But thank you so much and I hope you get your crystal ball back ;) – Araf Haque May 18 at 17:49
• Never use x^2 or x^3 in calculations! x*x and x*x*x are both faster and more reliable. – John Kormylo May 18 at 21:46

Welcome to TeX-SE! Since you do not provide us with the code that produced the error, and since my crystal ball got stolen, I can only guess. There is a chance that you tried to plot the LaTeX code that typesets the function. However, you need to plot the function itself.

\documentclass[tikz,border=3.14mm]{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.16}
\begin{document}
\begin{tikzpicture}
\begin{axis}
