\begin{figure}
\begin{tikzpicture}
    \begin{axis}[
        scaled y ticks = false,
        yticklabel style={/pgf/number format/fixed},
        %width  = 2.85*\textwidth,
        height = 8cm,
        ybar=1*\pgflinewidth,
        bar width=5pt,
        ylabel = {y-axis},
        symbolic x coords={A,B,C},
        xtick = data,

    ]
        \addplot[style={mark=none}]
            coordinates {(A, 0.0078)(B, 0.0059)(C, 0.00089)};

        \addplot[style={mark=none}]
