I was wondering if there is a way to add swimlanes to a flowchart in tikz? There is a flowchart package for tikz and that is great. But for a specific application I am working on, I need to include swimlanes. I have an example of such a diagram from Lucidchart, but was hoping I could do this in tikz too.

Just to clarify, by "swimlanes" I mean the horizontal rows in the diagram that represent some group's ownership of that flowchart block.

I found this post as well, but I am not creating a sankey diagram. Not sure if I can get the lanes with a flowchart from his package or post.

Type of sankey diagram

Sample diagram:

  • @marmot thanks for the tip. I was actually just hoping to see if there is a package in tikz to add these lanes. I don't even need the full code, just the right package to look at :). I also did add some extra text to clarify the meaning of "swimlane" as you suggested. Thanks for that.

    OK I see. It is certainly possible to create such a layout with TikZ, and it is not particularly difficult. (I would probably just do a rotated version of something of this sort.) Whether or not there is a dedicated package for that, I do not know.

  • Okay, the diagram you suggested seems doable. Is there a way to get that kind of "frame" around the boxes though? I know how to create a grid in tikz, but not sure how to create frames of the type in the picture above.

    Yes, of course. Either with the fit library or using local bounding box or "just so". What is best depends on the actual situation (and taste).

    Oh thanks so much. That is great. I have been trying to figure out how to repicate one of my diagrams in tikz and you have set me on the right path. I really appreciate it.

Assuming that you already have some code, like this one

\documentclass[tikz]{standalone}
\usetikzlibrary{shapes}
\tikzset{
    recgray/.style={draw,minimum width=3cm,minimum height=2cm,align=center,text width=3cm,fill=gray!50,font=\sffamily},
    rndgray/.style={rounded corners=1cm,draw,minimum width=3cm,minimum height=2cm,align=center,text width=3cm,fill=gray!50,font=\sffamily},
    recgren/.style={draw,minimum width=3cm,minimum height=2cm,align=center,text width=3cm,fill=green!50,font=\sffamily},
    diagren/.style={diamond,draw,minimum width=3cm,minimum height=2cm,align=center,text width=3cm,fill=green!50,font=\sffamily,aspect=1.5},
}
\begin{document}
\begin{tikzpicture}[x=4.5cm,y=2cm]
\node[rndgray] (cus1) at (0,3) {Order generated};
\node[recgray] (sale1) at (0,1) {Order completed};
\node[recgray] (cre1) at (0,-1) {Order received};
\node[recgray] (ware1) at (0,-3) {Order entered};
\node[recgren] (cre2) at (1,-1) {Check credit};
\node[diagren] (cre3) at (2,-1) {OK?};
\node[recgray] (cre4) at (4,-1) {Invoice prepared};
\node[recgray] (cre5) at (5,-1) {Invoice sent};
\node[recgren] (sale3) at (2,1) {Credit problem\\addressed};
\node[diagren] (sale4) at (3.75,1) {OK?};
\node[rndgray] (sale5) at (4.75,1) {Order generated};
\node[recgray] (ware4) at (4.25,-3) {Packages assembled};
\node[recgray] (ware5) at (5.25,-3) {Order shipped};
\node[rndgray,minimum width=4.5cm,text width=4.5cm] (x) at (5.5,3) {Process payment};
\begin{scope}[every path/.style={-latex}]
\draw (cus1) edge (sale1)
    (sale1) edge (cre1)
    (cre1) edge (cre2)
    (cre2) edge (cre3)
    (cre3) edge node[midway,fill=white,inner sep=2pt] {Yes} (cre4)
    (cre4) edge (cre5)
    (cre3) edge node[midway,fill=white,inner sep=2pt] {No} (sale3)
    (sale3) edge (sale4)
    (sale4) edge node[midway,above] {No} (sale5)
    (sale4) edge node[midway,fill=white,inner sep=2pt] {Yes} ++(0,-1.5)
    (cre1) edge (ware1)
    (ware1) edge (ware4)
    (ware4) edge (ware5);
\draw (cre5.north east) -- ++(0,3);
\draw (ware5.north east) -- ++(0,5);
\end{scope}
\end{tikzpicture}
\end{document}

You only have to add some rectangles and some normal nodes. \foreach may be very helpful here.

\documentclass[tikz]{standalone}
\usetikzlibrary{shapes}
\tikzset{
    recgray/.style={draw,minimum width=3cm,minimum height=2cm,align=center,text width=3cm,fill=gray!50,font=\sffamily},
    rndgray/.style={rounded corners=1cm,draw,minimum width=3cm,minimum height=2cm,align=center,text width=3cm,fill=gray!50,font=\sffamily},
    recgren/.style={draw,minimum width=3cm,minimum height=2cm,align=center,text width=3cm,fill=green!50,font=\sffamily},
    diagren/.style={diamond,draw,minimum width=3cm,minimum height=2cm,align=center,text width=3cm,fill=green!50,font=\sffamily,aspect=1.5},
}
\begin{document}
\begin{tikzpicture}[x=4.5cm,y=2cm]
%---
\foreach \i in {-4,-2,0,2} {
    \draw (-.75,\i) rectangle (6.25,\i+2);
    \draw (-.75,\i) rectangle (-.5,\i+2);
}
\node[rotate=90,font=\sffamily] at (-.625,1) {Sales};
\node[rotate=90,font=\sffamily] at (-.625,3) {Customer};
\node[rotate=90,font=\sffamily] at (-.625,-1) {Credit/Invoicing};
