# Visualize the attached diagram with Tikz

Is there a way in Tikz to draw a diagram like this?

• I think the answer is probably: Yes. – Johannes_B Nov 8 at 17:51

• Welcome to TeX.SX! You can have a look at our starter guide to familiarize yourself further with our format. – Holene Nov 8 at 17:55
• Ok so i've looked up the doc of tikz-cd but there is no "no arrow" that equals these entail symbols – Rack Cloud Nov 8 at 17:56

To give you a start. The shift of -6pt is explained as twice the inner sep plus the outer sep, all of which have default values of 2pt. Solutions using \makebox to achieve the same screw up the bounding box.

\documentclass{article}
\usepackage{tikz-cd}
\begin{document}
\begin{tikzcd}[every arrow/.append style={%
double distance=0.4ex,cyan,-{Bar[width=1.6ex]}}]
& \varphi_3\arrow[dl]\arrow[d]\\
\varphi_2 \arrow[ddr,shift right=1ex] &
|[label={[xshift=-6pt]right:\equiv\varphi_6}]|\varphi_1 \arrow[d]\\
&\varphi_4\arrow[d]\\
&\varphi_6\\
\end{tikzcd}
\end{document}


I do not know if the red marks are on purpose in your screen shot. If they are, it is easy to add them as long as it is clear what they are (check marks, brackets, ???).

• Damn thanks mate. Could you explain the change of arrows so in the future i know how to change them? – Rack Cloud Nov 8 at 18:07
• @RackCloud All I did was to add every arrow/.append style={double distance=0.4ex,cyan,-{Bar[width=1.6ex]}} to control their appearance. double distance=<distance> means that they are drawn as double lines separated by <distance>, cyan is a color and the Bar arrow head can be looked up in section 16.5 Reference: Arrow Tips of the pgfmanual v3.1.4. – Schrödinger's cat Nov 8 at 18:11
• \begin{tikzcd} & \varphi_7 \equiv\varphi_8 \arrow[d] \end{tikzcd} now i want to add a diagram that 7 equals 8 tried to just delete the other points but it didn't work am new to tikz and latex – Rack Cloud Nov 8 at 18:25
• Got it \begin{tikzcd} & \varphi_7\equiv\varphi_8 \end{tikzcd} – Rack Cloud Nov 8 at 18:26
• @RackCloud If you say \arrow[d] in a given cell, then you need to make sure that a cell below that cell exists. So e.g. \begin{tikzcd} & \varphi_7 \equiv\varphi_8 \arrow[d] \\ & {} \end{tikzcd} will work. – Schrödinger's cat Nov 8 at 18:27
