Math & Science ⇒ Underbraces

[avp3000]

Hello,

I want to start an equation with align* and than have the following (I don't use the equal sign, I just use the environment because of \underbrace)

first row

Code: Select all

1
\text{SMP}+\text{Capacity payment}
 
 
הההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההה
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

second row

Code: Select all

1
\text{PPP}+Uplift

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

!!!HOWEVER!!! I want an underbrace under SMP+Capacity payment that is concentrated ONLY above PPP. This means I want to show that SMP+Capacity Payment=PPP

third row

Code: Select all

1
\text{PSP}
 
 
הההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההה
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

with an underbrace under PPP+Uplift, concentrated on PSP.

That's an approximation, but still the underbraces are missing:

Code: Select all

1
2
3
4
5
begin{tabular}{ccc}
SMP & CP & \\
\multicolumn{2}{c}{PPP} & Uplift\\
\multicolumn{3}{c}{PSP}
\end{tabular}

Can anyone help me? Thank you very much (bow)

My inclination would be to try to this with some kind of upside down tree.

For example, the following gives you something kind of close to what you want, though I think it should probably be tweaked somewhat:

      \begin{tikzpicture}[level distance=2\baselineskip, edge from parent path=
                {(\tikzparentnode.north) .. controls +(0,.3) and +(0,-.3)
                   .. (\tikzchildnode.south)}]
                     \node {PSP} [grow=up]
                       child {node {Uplift}} 
                       child {node {PPP}        
                 child {node {CP}}
                             child {node {SMP}}
                             };
       \end{tikzpicture}

Run LaTeX here

Then again, simpler solutions may well exist!

Actually, I found a solution I like better, just using amsmath:

Code: Select all

Code, edit and compile here:

\documentclass{article}
\usepackage{amsmath}
\begin{document}
\[  \newlength{\ppplen}\settowidth{\ppplen}{$\overset{\underbrace{\text{SMP} \qquad \text{CP}}}{\text{PPP}}\text{PPP}$}
    \overset{\underbrace{\text{SMP} \qquad \text{CP}}}{\text{PPP}}\hspace{-.5\ppplen}
    \underbrace{\phantom{\text{PPP}} \qquad \text{Uplift}}_{\text{\normalsize PSP}}
\]
\end{document}

Don't ask me to explain that. It's kind of convoluted.

But actually, I bet there are even better solutions, and someone more knowledgeable will be along any minute to explain what and why.

Hello frabjous,

This was EXACTLY what I wanted. Thank you very much! Both solutions are very good, but I think I prefer tha second one. Thanky you very much.

Cheers
