is there any particular way to get something similar to that in tikz with or without any packages?

Arrows around equation in order to annotate

  • 1
    Yes. What have you tried so far? – fractal Jan 1 at 10:54
  • Nothing really since I never used tikz for more then using \addplot. But I searched the site for help and found some questions with arrows between textboxes which is not exactly what I need but made me think that there might be a way to get an equation annotated as well. – Nadine Jan 1 at 10:59

This is a continuation of Fractal's nice answer the purpose of which is to make the formulae fit in the document without overlapping.

Blah blah blah blah blah blah blah blah blah\dots
\begin{tikzpicture}[overlay,remember picture,cyan,>=stealth,shorten
 <=0.2ex,nodes={font=\tiny,align=left,inner ysep=1pt},<-]
  \draw ([xshift=-0.3ex]b.west|-x2) -- ++ (-1.5em,0) node[left] (l) {\textbf{Integral}};
  \draw (a.south) -- ++ (0,-1.5em) node[anchor=north west,align=left,xshift=-1.2ex]
    (u) {\textbf{Untergrenze}\\ Untere integrationsgrenze};
  \draw (b.north) -- ++ (0,1.5em) node[anchor=south west,align=left,xshift=-1.2ex]
    (o) {\textbf{Obergrenze}\\ Obere integrationsgrenze};
  \path (x1.north) ++ (0,1.5em) node[anchor=south west,xshift=-1.2ex] (il)
    {\textbf{Integrand}\\ Funktion \"uber die integriert werden soll};
  \draw (x1.north) |- ([xshift=0.3ex]il.south east);
  \path (d.south) ++ (0,-1.5em) node[anchor=north west] (diff)
  \draw (d.south) |- ([xshift=0.3ex]diff.south east);
  \draw ([xshift=0.3ex]x2.east) -- ++ (1.5em,0) node[right]  (r)
   {\textbf{Integrationsvariable}\\ Der Integrand wird \"uber $x$ integriert};
  \path let \p1=($(o.north)-(u.south)$),\p2=($(r.east)-(x2.east)$),
   \p3=($(a.west)-(l.west)$),\n1={\x2-\x3} in

    Thank you so much! This is perfect! I was trying do edit Fractal's answer to add the snaped arrows but could not get the text above the line. That really helps. Thanks again and happy New Year. – Nadine Jan 1 at 12:55

    @jsbibra forest is great for trees, and not necessarily ideal for what is asked here. – user194703 Feb 14 at 3:52
  • @Schrödinger'scat agreed-- just wanted to know if there was a way to choose different anchor points on a parent like its done with tikzmarknode – js bibra Feb 14 at 3:54

This is a start.

  _{\tikzmarknode[inner sep=.2em]{a}{a}}
\begin{tikzpicture}[overlay,remember picture,cyan,>=Stealth]
  \draw[<-] (int) -- ++ (-1,0) node[left] {{\bfseries Integral}};
  \draw[<-] (a) -- ++ (0,-1) node[anchor=168,align=left]
    {{\bfseries Some bold text}\\Some lighter text about something};
