I've tried to create something like this: Minimum Working Example (MWE): documentclass{standalone} usepackage{pgfplots} begin{document} begin{tikzpicture} begin{axis}[domain=0:1] addplot+[no marks, samples=100] {exp(3*x)}; addplot+[no marks, samples=100] {(-exp(3*x)+20)}; end{axis} end{tikzpicture} end{document} Screenshot of the current state: Description of the issue: However, I don't get the point on how to figure out the function of the third graph as well as how to clip the graphs in x and y direction to align them centered in the plot. It is not necessary to be completely precise, the accuracy of my upper template w...
