I have a commutative diagram written as a diagram environment defined using the package pb-diagram
. I'm very satisfied with the appearance of the diagram.
However I need to change some arrows to dashed arrows.
In the pb-diagram
manual it is stated that the option for the shaft of an arrow are:
.. | dotted or dashed arrow shaft
= | double line shaft* (“equals sign”)
! | invisible arrow shaft
For instance the command \arrow{e,..}
should draw a dotted or dashed arrow shaft.
My question is? How can I make sure that the arrow is dashed instead of dotted? In all examples I tried, the arrow becomes dotted.
I would appreciate any suggestions on how to solve this issue in pb-diagrams
. A minimal example is the following.
\documentclass[12pt]{article}
\usepackage{pb-diagram}
\begin{document}
\begin{equation}
\begin{diagram}
\node{A}
\arrow{e,t,..}{a}
\arrow{s,l,..}{c}
\arrow{ese,b,1,..}{u}
\node{B}
\arrow{e,t,..}{b}
\node{C}
\arrow{s,r}{d}
\arrow{wsw,b,1}{v} \\
\node{D}
\arrow[2]{e,b}{e}
\node[2]{H}
\end{diagram}
\end{equation}
\end{document}
All dotted arrows should be dashed arrows.
OBS: I'm aware of the existence of a more advanced package called TikZ, which is more expressive and apparently allows one to have great control of the diagrams. But in this question I'm only interested in how to solve the problem with respect to the package pb-diagram
, since the diagram, which is pretty large, is already coded and I just need to add some dashed arrows to finalize it. Additionally, I'm having some trouble to install TikZ on my computer.
picture
environment which is used by this package. So I am sorry, but I am stuck here. Is your diagram really that big? Maybe it would be easier to post it here and I rewrite it intikz-cd
which can do this easily. If you want this inpb-diagram
, please write a feature request to Paul Burchard..
, since it uses\circle
