diagrams
I am trying to draw a ripple pendulum similar to the below diagram but have absolutely no idea how to start, or even if it can be done in LaTeX? Another complication is I need it to have a purple background
backgroundcolor=blue!20
Here is the diagram I am trying to draw. Thank you for any help or guidance 🙂
For a start, this may serve some help.
Here is the code that generates it.
[relative location]\draw (A)--(B) or \draw (C) |- (D) for sharp angle. Code:
\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}[-,auto,node distance=2cm]
\tikzstyle{point}=[coordinate]
\tikzstyle{block}=[draw, rectangle, minimum height=2em, minimum width=4em]
\node[point] (0) {};
\node[point] (1) [right of=0] {};
\node[block] (2) [above right of=1] {C1};
\node[block] (3) [right of=2] {M1};
\node[block] (4) [right of=3] {S1};
\node[block] (5) [right of=4] {A1};
\node[point] (6) [below right of=5] {};
\node[block] (7) [below right of=1] {C2};
\node[block] (8) [right of=7] {M2};
\node[block] (9) [right of=8] {S2};
\node[block] (10) [right of=9] {A2};
\node[point] (11) [right of=6] {};
\draw [thick] (7) -| (1) (2) -| (1) (0) -- (1) (2) -- (3);
\draw [thick] (4) -- (5) (7) -- (8) (9) -- (10) (11) -- (6);
\draw [thick] (10) -| (6) (6) -- (11) (5) -| (6);
\draw [thick] (3) -- node [name=sm1]{} (4);
\draw [thick] (4) -- node [name=sa1]{} (5);
\draw [thick] (8) -- node [yshift=-0.22cm, name=sm2]{} (9);
\draw [thick] (9) -- node [yshift=-0.22cm, name=sa2]{} (10);
\draw [thick] (sm1) -- (sm2) (sa1)--(sa2);
\end{tikzpicture}
\end{document}
You can use positioning library and a useful reading will be this question. Further, tikzstyle is deprecated, use tikzset instead.
\documentclass[border=10pt]{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows,positioning,shapes.geometric}
\begin{document}
\begin{tikzpicture}[>=latex']
\tikzset{block/.style= {draw, rectangle, align=center,minimum width=2cm,minimum height=1cm},
rblock/.style={draw, shape=rectangle,rounded corners=1.5em,align=center,minimum width=2cm,minimum height=1cm},
input/.style={ % requires library shapes.geometric
draw,
trapezium,
trapezium left angle=60,
trapezium right angle=120,
minimum width=2cm,
align=center,
minimum height=1cm
},
}
\node [rblock] (start) {Start};
\node [block, right =2cm of start] (acquire) {Acquire Image};
\node [block, right =2cm of acquire] (rgb2gray) {RGB to Gray};
\node [block, right =2cm of rgb2gray] (otsu) {Localized OTSU \\ Thresholding};
\node [block, below right =2cm and -0.5cm of start] (gchannel) {Subtract the \\ Green Channel};
\node [block, right =2cm of gchannel] (closing) {Morphological \\ Closing};
\node [block, right =2cm of closing] (NN) {Sign Detection \\ Using NN};
\node [input, right =2cm of NN] (limit) {Speed \\ Limit};
\node [coordinate, below right =1cm and 1cm of otsu] (right) {}; %% Coordinate on right and middle
\node [coordinate,above left =1cm and 1cm of gchannel] (left) {}; %% Coordinate on left and middle
%% paths
\path[draw,->] (start) edge (acquire)
(acquire) edge (rgb2gray)
(rgb2gray) edge (otsu)
(otsu.east) -| (right) -- (left) |- (gchannel)
(gchannel) edge (closing)
(closing) edge (NN)
(NN) edge (limit)

\end{tikzpicture}

One LaTeX-friendly tool for doing this type of drawing is MetaPost. Getting started details are in the linked answer.
One technique for filling the background of an image, is to save the whole drawing in a
picturevariable, and then fill thebboxof the picture with the background colour, and then draw the picture on top.Here's an example using a version of the OP image.
