I am trying to draw this spectrum in Arabic similar to the one below. I want it to have 10 arrows. I also want to close the gap between the two arrows. My code is:

**NOTE: Don't worry about the Arabic. You can make it all in English. I will do the Arabic part.**

```
\documentclass[border=10pt,12pt,crop,tikz,convert={outext=.svg,command=\unexpanded{pdf2svg \infile\space\outfile}},multi=false]{standalone}[2012/04/13]

    \begin{tikzpicture}[every node/.style={single arrow, draw=none,minimum height=4.95cm,minimum width=1.2cm}]
    \node [draw=gray,fill=gray, text=white] (C) at (7.35,5) {\textarabic{غير توجيهي}};
    \node [draw=gray,fill=gray,shape border rotate=180, text=white] (P) at (2.65,5) {\textarabic{توجيهي}};
    \draw[<-,very thick,black] ($(C.south)+(.058cm,.02cm)$) -- ++(0,-12pt) node[below] (L1) {\textarabic{سلوك استثنائي}};
