I am using the latest TeXstudio version with PdfLaTeX as my compiler. I have this commands enabled: pdflatex.exe -synctex=1 -shell-escape -interaction=nonstopmode %.tex
. The document is getting created but TikZ does not draw the functions. The Code works in Overleaf (online editor) perfectly fine with the drawn functions so there must be a problem with my PdfLaTeX or my TeXstudio. I tried reinstalling MikTeX and TeXstudio. I have even installed on a virtual machine to look if it works there but without success. It also does not work in WinShell. I also tried to compile the document with LuaLaTeX but again, without success. Furthermore, Overleaf's default compiler was set to PdfLaTeX. I thinks that there is something wrong with my PdfLaTeX but I have no idea left for a possibility to solve that problem. My Code is:
\documentclass{article}
\usepackage{pgfplots}
\usetikzlibrary{through,calc,arrows,snakes}
\pgfplotsset{compat=1.16}
\begin{document}
\begin{center}
\begin{tikzpicture}[scale=0.8, x=2cm, y=2cm, axis/.style={ ->, >=stealth'}]
\draw[dotted,color=black, xstep=1cm, ystep=1cm] (-1.9,0) grid (1.9,3.9);
\draw[axis] (-2,0) -- (2,0) node[above] {\small $x$};
\draw[axis] (0,0) -- (0,4) node[right] {\small $y$};
\foreach \x/\xtext in {-2/-2, -1/-1, 0/0, 1/1} \draw[shift={(\x,0)}] (0pt,2pt) -- (0pt,-2pt) node[below, fill=white] {\small \xtext};
\foreach \y/\ytext in {1/1, 2/2, 3/3} \draw[shift={(0,\y)}] (2pt,0pt) -- (-2pt,0pt) node[left, fill=white] {\small \ytext};
% functions
\draw[color=red, thick] plot[domain=-2:2, samples=250] function{x*x} node[right] {\small $f(x)$};
\end{tikzpicture}
\end{center}
\end{document}
As you can see on the left it looks perfectly fine (Overleaf) but on the right (TeXstudio) it doesnt. I want to continue writing in TeXstudio not in Overleaf so it would be great if this is working.
gnuplot
installed and is it in yourPATH
?\usepackage{pgfplots}
and even set thecompat
. -but you are not using it at all. Why draw axis, grid, scale, ticks and the plot manually? Search for PGFPlot examples here or google.
