# How do I make a time gap in LaTeX using tikz-timing?

Is there a way to make a timing gap using the tikz-timing package or tikz, like the timing gap highlighted in the picture below?

• Just one more thing: an almost identical question (I believe) has been asked here, also without MWE. As you see, there is no answer. So, if you want to have a timely answer (and also avoid that your question is being closed), please consider posting an MWE.

• Yes there is a reference to an web api, with online editor to make this wavedrom, its an open source HTML5 and has the option implemented for gaps, for the tikz-timing, in a quick view I did not find something similar, only dotted separations. Maybe, if you provide the precious and required MWE, some experts can do it using their best tricks in the tikz way ... May 16, 2018 at 3:35

(Because I was a bit bored:) Note, there are bound to be several other ways of doing the same thing, and likely better ways. I define a style for a node, and draw the gap symbol as a path picture. The placement will depend on your diagram. In this case note the timing specification (2L N(A1) 4H N(A2) L) includes two named nodes A1 and A2, and the gap node is placed using those as a reference.

\documentclass[border=5mm]{standalone}
\usepackage{tikz-timing}
\usetikzlibrary{calc}

\tikzset{
alias path picture bounding box/.code=%https://tex.stackexchange.com/q/395628
\pgfnodealias{#1}{path picture bounding box},
gap/.style={
circle,
inner sep=0pt,
minimum size=#1,
node contents={},
path picture={
\tikzset{alias path picture bounding box=@}
\fill [white] (@.265) to[out=40,in=220] (@.70) --
(@.85)  to[out=220,in=40] (@.250) -- cycle;
\draw [very thin] (@.265) to[out=40,in=220] (@.70)
(@.85)  to[out=220,in=40] (@.250);
}
},
gap/.default=10pt
}
\begin{document}
\begin{tikztimingtable}
foo & 2L N(A1)  4H N(A2) L\\
\extracode
\node[gap, at={($(A1|-A2)!0.5!(A2)$)}];
\end{tikztimingtable}
\end{document}

• What does ($(A1|-A2)!0.5!(A2)$) mean? Apr 10, 2021 at 13:03
• @Michael ($(a)!0.5!(b)$) is the point halfway between a and b, and (a|-b) is the point that has the x-coordinate of a and the y-coordinate of b (tex.stackexchange.com/questions/401425). Apr 10, 2021 at 15:29
• If I want to draw a gap at A1 I just need to use $A1$? Apr 11, 2021 at 0:30
• @Michael No, the dollar signs are for coordinate calculations, use just at={(A1)} Apr 11, 2021 at 13:57
• Thank you. It is strange that there is no a standard way to insert a gap. Apr 12, 2021 at 0:46
