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.
