[Tex/LaTex] Drawing a scheme

Question

I am writing my assignment in LyX. I am very new to this program, but I would like to create a scheme similar to this:

Is this possible to do? Does anyone have templates similar to this one?
I would appreciate your help.

Answer 1

You could use tikz directly in LyX.

Choose Document --> Settings --> LaTeX preamble and add these two lines:

\usepackage{tikz}
\usetikzlibrary{matrix,shapes}

Then, in your document - within a figure environment (since I wrote \centering it should be put within a group), or a center environment directly (without \centering) or any other similar way you like - put the following code in an ERT (pressing ctrl+L or the specific icon or via menu Insert --> TeX code). Note that when pasting code into an ERT you must use Ctrl + Shift + V (Edit -> Paste special) to preserve line breaks.

\centering\noindent%
\begin{tikzpicture}[        
    ellipsenode/.style={
        ellipse, 
        fill=orange,
        inner sep=4pt,
        text width=5em, 
        text=white,
        text centered
    },
    rectnode/.style={
        rounded corners, 
        fill=#1,
        inner sep=10pt,
        text=white,
        text width=7em, 
        text centered
    },
    graynode/.style={
        draw=gray,
        very thick,
        inner sep=4pt,
        text=gray,
        text centered
    },
    myline/.style={
        draw=#1,
        line width=1.5pt,
    },
    ]
    \matrix[
        matrix of nodes,            
        column sep=1.2em, 
        row sep=4ex, 
        row 1/.style={nodes={ellipsenode}},
        row 2/.style={nodes={rectnode={black}}},
        row 3/.style={nodes={graynode}},
        row 4/.style={nodes={rectnode={black}}},
        row 5/.style={nodes={rectnode={orange}}},
    ] (m) {
    {\textbf{Investor} \\ \textit{\small(LP)}} & {\textbf{Investor} \\ \textit{\small(LP)}} & {\textbf{Investor} \\ \textit{\small(LP)}} \\                 
    & {\textbf{General} \\ \textbf{Partner} \textit{\small(GP)}} \\
    & Limited Partner Agreement \\
    & {\textbf{Limited} \\ \textbf{Liability}\\ \textbf{Partnership}\\ \textit{\small(LLP)}} \\
    {\textbf{Portfolio} \\ \textbf{Companies}} & {\textbf{Portfolio} \\ \textbf{Companies}} & {\textbf{Portfolio} \\ \textbf{Companies}} \\             
    };  
    \draw[myline=orange] (m-1-1.south) |- (m-4-2)
        (m-1-2.west) -- ++(-3em,0) |- (m-4-2.165)
        (m-1-3.south) |- (m-4-2)
        (m-4-2.south) -- (m-5-2)
        (m-4-2.south) -- ++(0,-2ex) -| (m-5-1)
        (m-4-2.south) -- ++(0,-2ex) -| (m-5-3)
    ;
    \draw[myline=gray, dashed] (m-1-1.-45) |- (m-2-2)
        (m-1-2) -- (m-2-2)
        (m-1-3.-135) |- (m-2-2)
    ;
    \draw[myline=orange, dashed] (m-2-2) -- (m-3-2) -- (m-4-2);
\end{tikzpicture}

After running and this is the result:

This is the complete code you could save with a .lyx extension and open directly in LyX:
