In my last question, here, I asked how to draw a curved line with a tensor below a node on it. Now I would like to draw a more complicated figure with tikz: a curved line with nodes and tensors on it that lie on a gradient background. Something like this:
Thanks for your help!
One option:
The code:
\documentclass[border=5pt]{standalone}
\usepackage{tensor}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\filldraw[left color=gray!30,right color=black!60]
(-2,-3) to[out=20,in=160]
(11,-2) to[out=110,in=230]
(13,4) to[out=180,in=20]
(-1,3) to[out=220,in=130]
cycle;
\draw[line width=2pt]
(0,0) ..controls (2,2) and (5,-1) .. (10,2)
node[fill,circle,minimum size=8pt,inner sep=0pt,pos=0.4,label=below:{$\tensor{g}{_a_b}$},label=above:{$t=0$}] {}
node[fill,circle,minimum size=8pt,inner sep=0pt,pos=0.8,label=below:{$\tensor{g}{_a_b}$},label=above:{$t$}] {};
\node at (10,-1) {$\tensor{h}{_a_b}$};
\end{tikzpicture}
\end{document}

Thanks. But first, the background is not gradient. How can I made it gradient? Second, I would like to write right bottom in the shape in background another tensor. With labeling a node at the corner I could not do this. – Astrolabe Oct 14 '15 at 15:54

@H.B. Please see my updated answer. Is it something like that what you need? – Gonzalo Medina Oct 14 '15 at 16:02
