[Tex/LaTex] Right-justifying vertical subfigures in a two-column document

adjustboxsubfloatstwo-column

I am trying to include a pair of subfigures in my two-column document, stacked one on top of the other. I want them to be right-justified; to achieve this with individual figures I have been using the adjustbox package. When I try to use this package with the subfigures however, it stops laying them out one on top of the other – despite the new line command. A MWE is below:

\documentclass[a4paper,11pt,twocolumn]{article}
%Used for figures
\usepackage{graphicx}
\usepackage{float}
\usepackage{adjustbox}
% Document margins
\usepackage[hmarginratio=1:1,top=32mm,columnsep=20pt]{geometry} 
%Deals with paragraph formatting
\usepackage{parskip}
%Allows sub-floats
\usepackage{subcaption}
%Text
\usepackage{lipsum}

%-------------------------------------------------------------%

\begin{document}

%Stop stretching of text on last page
\raggedbottom

\section{Introduction}

\lipsum[2]

\begin{figure}[H]
\begin{adjustbox}{right}
        \begin{subfigure}[H]{0.6\textwidth}
                \includegraphics[width=\textwidth]{graph1}
                \caption{Graph1.}
                \label{fig:graph1}
        \end{subfigure}
\\
     \begin{subfigure}[H]{0.6\textwidth}
                \includegraphics[width=\textwidth]{graph2}
                \caption{Graph2.}
                \label{fig:graph2}
        \end{subfigure}
\end{adjustbox}
\caption{Graphs}\label{fig:graphs}
\end{figure}

\lipsum[1]

\end{document}

Thanks

You can get the two subfigures stacked vertically and sticking out to the left by encasing them in separate adjustbox environments. Incidentally, observe that there's no point in specifying the [H] positioning specifier for the two subfigure environments. And, as @Sigur has already noted in a comment, do use \columnwidth rather than \textwidth for the widths of the subfigures and \linewidth for the width of the graphs.

To reproduce just the figure-related code:

\begin{figure}[H]
\begin{adjustbox}{right}
   \begin{subfigure}{1.2\columnwidth}
      \includegraphics[width=\linewidth]{graph1}
      \caption{Graph1.}
      \label{fig:graph1}
   \end{subfigure}
\end{adjustbox}

\begin{adjustbox}{right}
   \begin{subfigure}{1.2\columnwidth}
      \includegraphics[width=\linewidth]{graph2}
      \caption{Graph2.}
      \label{fig:graph2}
   \end{subfigure}
\end{adjustbox}
\caption{Graphs}\label{fig:graphs}
\end{figure}

The resulting figure looks like this (note that I had to load the graphicx package since you didn't post the graphs referenced in the code):
