I want to refine the following diagram. I want to left allign the text showing on the left of this diagram and need straight paths. Any help will be highly appreciated. Thanks

Here is another version.

\documentclass[tikz,margin=5]{standalone} \usepackage{tikz} \usetikzlibrary{arrows,calc,fit} \tikzset{ -> , >=stealth' , shorten >=1pt, my node/.style = {align=left,anchor=west}, your node/.style={above,pos=1,xshift=-2cm,text = red} } \begin{document} \begin{tikzpicture} \node[my node] (TotalNi) at (0,0) {Total Ni}; \node[my node] (AN) at (0,-1) {AN}; \node[my node] (CC) at (0,-2) {CC}; \node[my node] (SC) at (0,-3) {SC}; \node[my node] (EDTA) at (0,-4) {EDTA}; \node[my node] (ABDTPA) at (0,-5) {ABDTPA}; \node[my node] (DTPA) at (0,-6) {DTPA}; \node[draw,rectangle,xshift=5cm] [fit = (TotalNi) (AN)(CC) (SC) (EDTA) (ABDTPA) (ABDTPA) (DTPA)] (u1) {\rotatebox{90}{Test}}; \draw[->](TotalNi.east) -- node[your node] {$-0.06557$} ($(u1.north west)!(TotalNi.east)!(u1.south west)$) ; \draw[->] (AN) -- node[your node,text = blue] {$\phantom{-}0.04305$} ($(u1.north west)!(AN.east)!(u1.south west)$) ; \draw[->] (CC) -- node[your node] {$-0.34954$} ($(u1.north west)!(CC)!(u1.south west)$) ; \draw[->] (SC) -- node[your node] {$-0.34954$} ($(u1.north west)!(SC)!(u1.south west)$) ; \draw[->] (EDTA) -- node[your node] {$-0.34954$} ($(u1.north west)!(EDTA)!(u1.south west)$) ; \draw[->] (ABDTPA) -- node[your node] {$-0.34954$} ($(u1.north west)!(ABDTPA.east)!(u1.south west)$) ; \draw[->] (DTPA) -- node[your node] {$-0.34954$} ($(u1.north west)!(DTPA.east)!(u1.south west)$) ; \end{tikzpicture} \end{document}

  • Thanks @HarishKumar for your nice answer. Would you guide me how to rotate the text (here Test) in the right most triangle. Thanks Commented Nov 3, 2014 at 8:17
  • @MYaseen208 Use \rotatebox as an ugly short cut. Commented Nov 3, 2014 at 8:42

I think that the code of the figure can be reduced (and imho improved) by using a foreach loop for the final part. In addition the syntax (a-|b) can be useful to specify the coordinate at which each line ends, being a the node containing the label and b the "west" side of the large box.

Also, since I noticed that the color of the numbers is based on their signs, this can be automated too.

Using these ideas, the code can be simplified to:

 % All the code up to the line % \node[draw,rectangle,xshift=5cm] [fit = (TotalNi) (AN)(CC) (SC) (EDTA) (ABDTPA) (ABDTPA) (DTPA)] (u1) {Test}; % remains identical % This loop draws all the lines and numbers \foreach \label/\amount in { TotalNi/-0.06557, AN/0.04305, CC/-0.34954, SC/-0.34954, EDTA/-0.34954, ABDTPA/-0.34954, DTPA/-0.34954} { \pgfmathparse{ifthenelse(\amount<0,"red","blue")} \path[above, pos=0.4, yshift=0.1cm, anchor=south, auto=false] (\label) edge node {\textcolor{\pgfmathresult}{$\amount$}} (\label-|u1.west); }
