For the code below the labels are at the base of each arc, I need them to be in the center.



\tikzset{ell/.style={ellipse,draw,minimum height=0.15cm,minimum width=0.2cm,inner sep=0.1cm}}

\node[ell] (e1)at (-3,0) {\color{blue}$1$};
\node[ell] (e2)at (3,0) {\color{blue}$2$};
\draw (-2,-1)--(-1,-1.5)--(-1.5,-2)--cycle;
\draw (2,-1)--(1.5,-2)--(1,-1.5)--cycle;
\node[ell] (e6)at (0,-3) {\color{blue}$6$};

\draw[<-](e1)--(-2,-1) node[left]{\color{red} \tiny $y_{11}$};
\draw[<-](e2)--(2,-1) node[right]{\color{red} \tiny $y_{21}$};
\draw[<-](-1.25,-1.75)--(e6) node[left]{\color{red} \tiny $y_{12}$};
\draw[<-](1.25,-1.75)--(e6) node[right]{\color{red} \tiny $y_{22}$};


  • I drew the triangles because I need them and I wasn't sure how else I could make them. But that is not the problem. My only concern is the position of the red labels. As I wrote, currently the red labels are at the base of each arc, but I need them to be in the center.

  • why did you draw that triangles? do you want to place some big arrows in the middle of the straight lines? Can you provide a hand-drawing of what you need, and the context of the figure (physics, chemistry)? Clearly your question is not so clear

    Not related, but you may find easier to draw your triangles as nodes (using shapes.geometric library) where you can use some options in a tikzset (minimum height, minimum width, rotate, etc.) so that you could address directly your arrows to these nodes instead of computing their coordinates.

Is that what you want? I am curious about the context and the meaning of the triangles. The decimal numbers in (1.25,-1.75) seems unnatural.

enter image description here

(-3,0) node (e1) {$1$}
(3,0)  node (e2) {$2$}
(0,-3) node (e6) {$6$}


\draw[<-] (e1)--(-2,-1) node[below left]{$y_{11}$};
\draw[<-] (e2)--(2,-1) node[below right]{$y_{21}$};
\draw[<-] (-1.25,-1.75)--(e6) node[below left]{$y_{12}$};
\draw[<-] (1.25,-1.75)--(e6) node[below right]{$y_{22}$};

    Yes, thank you! This is exactly what I wanted. The actual picture in fact is much bigger and the triangles have a different meaning than the circular nodes, I just gave a simplified version by removing other parts of the picture.
