% Diesen PLot habe ich in der Diss als Tabelle
|
||||
|
||||
% Create a compact 3-column by 4-row MPI time-signal figure table in LaTeX.
|
||||
%
|
||||
% Use these plots from 04_Experimental_Evaluation/tikz/mpi/:
|
||||
% - columns: SIR = 20 dB, 30 dB, 50 dB
|
||||
% - rows: path length = 1 m, 20 m, 300 m, 1000 m
|
||||
% - file pattern: mpi_timesignal_<pathlen>m_<sir>_db.tikz
|
||||
%
|
||||
% Use a tabular layout with thin black table gridlines:
|
||||
% - \arrayrulewidth = 0.2pt
|
||||
% - \arrayrulecolor{black}
|
||||
% - vertical and horizontal rules around all cells
|
||||
% - rotated row labels for 1 m, 20 m, 300 m, 1000 m
|
||||
% - center the rotated row labels vertically against the plot cells
|
||||
% - use a dedicated left-column macro so the SIR 20 dB plots are slightly wider:
|
||||
% - left column fwidth = 0.255\textwidth
|
||||
% - inner columns fwidth = 0.240\textwidth
|
||||
% - all fheight = 0.102\textheight
|
||||
%
|
||||
% For the TikZ plot files used in the table:
|
||||
% - leftmost/SIR 20 dB plots keep the y-label:
|
||||
% ylabel={Norm. Amplitude}
|
||||
% - SIR 30 dB and 50 dB plots have no y-label:
|
||||
% ylabel={}
|
||||
% - SIR 30 dB and 50 dB plots hide y ticks:
|
||||
% ytick=\empty
|
||||
% - axis labels and tick labels use scriptsize:
|
||||
% every axis/.append style={font=\scriptsize}
|
||||
% xlabel style={font=\color{white!15!black}\scriptsize}
|
||||
% ylabel style={font=\color{white!15!black}\scriptsize}
|
||||
% - sigma annotation node boxes use tiny:
|
||||
% \node[font=\tiny, ...]
|
||||
% - node boxes:
|
||||
% inner sep=0.5pt
|
||||
% at (axis cs:10,...)
|
||||
% sigma labels use normal math subscripts, e.g. $\sigma^2_2$, not $\sigma^2\_2$
|
||||
% - all plotted line widths and grid style widths were normalized as needed:
|
||||
% addplot line width=1.0pt
|
||||
% - grid should be visually off:
|
||||
% remove xmajorgrids and ymajorgrids
|
||||
% keep style definitions available:
|
||||
% grid style={line width=0.4pt, solid, color=black!20}
|
||||
% minor grid style={line width=0.2pt, solid, color=black!10}
