Graphics, Figures & Tables ⇒ Tikz General Curve

[coachbennett1981]

Hey Everyone,

I am trying to figure out how to draw a generic curve using tikz. Like the picture attached. I don't know where to begin. I can handle the axis using the \draw command and the nodes, but a general curve is where I get stuck. I know how to plot function in Tikz and PGF, but not something as random.

Any help would be appreciated.

You could use the hobby library with a few points as samples:

Code: Select all

\documentclass[tikz,border=10pt]{standalone}
\usetikzlibrary{hobby}
\begin{document}
\begin{tikzpicture}
  \draw plot [hobby] coordinates {(0,4) (1,3.2) (2,1.5) (2.5,1.2) (3,1) (4,0.8)};
\end{tikzpicture}
\end{document}

With basic TikZ, smooth instead of hobby could be ok, perhaps not so nice and round.
