Aproximando as partes de um gráfico de barras

Question

No MWE abaixo:

\documentclass{report}
\usepackage[left=2.5cm,right=2cm,top=2cm,bottom=2cm]{geometry}
\usepackage[T1]{fontenc}
\usepackage{tikz,pgf}


\usepackage{pgfplots}
\usepackage{slashbox}
\usepackage{bchart}


\usetikzlibrary{calc,trees,positioning,arrows,chains,shapes.geometric,%
    decorations.pathreplacing,decorations.pathmorphing,shapes,%
    matrix,shapes.symbols,automata}

\begin{document}

\begin{figure}[H]
\centering
\begin{tikzpicture}
\begin{axis}[
ybar,
ylabel={Time Elapsed (in hours)},
xlabel={Methods},
legend style={at={(0.5,-0.15)},
anchor=north,legend columns=-1},
width=0.7*\textwidth,
height=9cm,
bar width=7pt,
symbolic x coords={Category-1,Category-2},
xtick=data,
ymin=0 
]

        \addplot
        coordinates {(Category-1,0.27) (Category-2,14.96)};

        \addplot
        coordinates {(Category-1,0.37) (Category-2,13.25)};

        \addplot
        coordinates {(Category-1,2.76)  (Category-2,29.55)};

        \addplot
        coordinates {(Category-1,2.82) (Category-2,16.03)};

        \legend{Original, byHalf, Random, Hybrid}
    \end{axis}
\end{tikzpicture}
\end{figure}

\end{document}

Como posso aproximar as duas partes (Categoria 1 e Categoria 2)?

Answer 1

Você pode aumentar o espaço em qualquer lado do gráfico definindo enlarge x limits=<value>. A configuração enlarge x limits=1funciona muito bem neste caso.
