[Tex/LaTex] get caption/subcaption every plot using groupplot pgf tikz

groupplotspgfplotssubcaption

Hello I want to have Under each plot (subgroup plot) its caption or label, so I can also reference it in my document.
Here in my example I used (a), (b), (c) I can keep them but they are not well aligned, and how to get them referenced in the text.
Thanks

Best Answer

You can load subcaption and caption packages and use \captionof inside a node like

\node[text width=6cm,align=center,anchor=north] at ([yshift=-5mm]my plots c1r1.south) {\captionof{subfigure}{Pressure relative (P/P)\label{subplot:one}}};

The node option textwidthis needed for\captionof` to work inside the node.

[Tex/LaTex] Plot alignment using groupplot in pgfplots

Thanks to Jake's suggestion, a significant compression of my original solution is possible (since I don't know a thing about tikz). Also, a new version of stackengine should hit the streets this weekend. The syntax I used here will work in both old and new versions. You can control the inter-plot separation, if desired (i.e., normal hspacing will work between the top two plots, and an optional length argument to \stackunder will define the vertical gap).

\documentclass{standalone}
\usepackage{stackengine}
\usepackage{tikz,pgfplots}
    \usepgfplotslibrary{groupplots}
\begin{document}
\stackunder{%
  \begin{tikzpicture}
    \begin{axis}[width=4cm, height=4cm] \addplot coordinates{%
      (0,0) (1,2) (2,1)}; \end{axis}
  \end{tikzpicture}
  \begin{tikzpicture}
    \begin{axis}[width=4cm, height=4cm] \addplot coordinates{%
      (0,0) (1,2) (2,1)}; \end{axis}
  \end{tikzpicture}
}{%
  \begin{tikzpicture}
    \begin{axis}[width=4cm, height=4cm] \addplot coordinates{%
      (0,0) (1,2) (2,1)}; \end{axis}
  \end{tikzpicture}
}
