I work with electrical power systems and always I need to plot voltage and current signals. Sometimes I need to plot boolean signals. I'm using pgfplots and groupplots specifically to do this work as shown in the first figure (with titles in portuguese) using the following code (headers not included):

Relay plots

The last plot is a boolean variable and I need to plot some variables like this, but I want to do this work like the second figure, where the boolean signals are in blue and there is a bar for values different from zero and line for values=0.

For help, the following full code only for digital input was included:

\addplot[red,very thick] table [x expr=\thisrow{Time}*1000, y={Tx}]   {\datosB};
\end{groupplot}
\end{tikzpicture}
\end{document}

The data file is FaltaBCplots.dat. The digital inputs of this file are similar to:

  • Welcome to TeX.Stackexchange! Why don't you show us the code for your boolean plot to give us something to start with?

  • Thanks. I edited the post and included the code and data.

Using some ideas from this post, I made a solution. I defined rectangle* and rectangle2* marks for non-zero and zero values respectively. I used two \addplot in order to plot one signal.

Signals A and B are the same because there is only one digital signal in the data file, but the figure shows that its possible to plot several digital signals in the same axes. The following code:

\PassOptionsToPackage{T1}{fontenc}

\pgfkeysdef{/pgf/mark color}{\def\pgf@mark@color{#1}}
