Colored fully bars in bar vertical plot

Question

I created a plot with pgfplots using this snippet of code:

\begin{figure}[htp]
\centering
    \begin{tikzpicture}
        \begin{semilogxaxis}[ybar stacked,ymajorgrids=true]
            \addplot [red]
                table [x=nodes,y=1]
                {./MATLAB/grafici/energia/broadcast_scenario/energy_broadcast_varpktslossprobability_100nodes.txt};
        \end{semilogxaxis}
    \end{tikzpicture}
\end{figure}

I got as result the correct plot, but the bars aren't fully colored. Only the borders of this bar are colored of red, instead I would like them fully colored also internally.

Answer 1

To fill a stacked bar it needs to add the command fill to \addplot and eventually draw to color the outside borders
