Re: [NTG-context] Place a text over an arrow (Metafun)

Hi Hans and Otared, I did not know this module (Context is so rich !), it's great ! thanks Fabrice 2016-07-25 11:29 GMT+02:00 Otared Kavian :

Hi Fabrice,

Do you know the step charts module in ConTeXt? I guess you can achieve what you want as in the example below (sorry, I did not took your example, I am just copying an example from my archives…).

%%%%%%%%%% \usemodule[steps] \starttext

Pour voir que la composée de deux fonctions $f$ et $u$, continues en un point $x_{*}$, est continue, on peut suivre le schéma suivant~: \placefigure[middle,none][-]{}{ %\scale[,width=.35\textwidth]{ \startSTEPtable \cell {$(f\circ u)(x_{*} + o(1)) = $} \text{définition de $f\circ u$} \cell {$f\left(u\left(x_{*} + o(1)\right)\right) = $} \text {$u$ est continue} \cell {$f\left(u(x_{*}) + o(1)\right) = $} \text {$f$ est continue} \cell {$f\left(u(x_{*})\right) + o(1) =$} \text {définition de $f\circ u$} \cell {$(f\circ u)(x_{*}) + o(1)$.} \stopSTEPtable %} } \stoptext %%%%%%%%%%

Hello, My way is not very elegant but I would do this:

Formula arrow text Formula arrow text Formula arrow text Formula

######################################################### \startuseMPgraphic{MyArrow} path p ; p:=(0,0){right}..(0.5cm,-0.6cm)..(0,-1.2cm){left} ; drawarrow p withpen pencircle scaled 1.5bp withcolor 0.625white ; \stopuseMPgraphic

\starttext

\showgrid

\math{A\times X=B}

\hfill On multiplie, à gauche, les deux membres de l'égalité par \math{A^{-1}}.

\hskip 5cm \relax \dontleavehmode\useMPgraphic{MyArrow}

\math{A^{-1}\times A\times X=A^{-1}\times B}

\hfill On utilise l'égalité \math{A^{-1}\times A=I}.

\hskip 5cm \relax \dontleavehmode \useMPgraphic{MyArrow}

\math{I\times X=A^{-1}\times B}

\hfill On utilise l'égalité \math{X\times I=I\times X=X}.

\hskip 5cm \relax \dontleavehmode \useMPgraphic{MyArrow}

On a donc \math{X=A^{-1}\times B}

\stoptext #########################################################

Thanks, Fabrice
