bordermatrixlabelsmath-mode
I'm needing to create a matrix enclosed with brackets [], not parentheses (), with row labels on right side. Is this possible using \kbordermatrix?
For instance, in the following:
\kbordermatrix{\mbox{}& C_1 & C_2& C_3\\
R_1&1&2&7\\
R_2&2&1&8
}
I would like the labels R_1 and R_2 to be on the right side of the matrix not the left.
Another way with TikZ similar to Highlight elements in the matrix:
\documentclass{article}
\usepackage{tikz}
\newcommand{\tikzmark}[1]{\tikz[overlay, remember picture] \coordinate (#1);}
\begin{document}
\[
M_{reg} = \qquad \bordermatrix{~ & \tikzmark{harrowleft} 0 & 1 & 2 & 3
& 4\tikzmark{harrowright} \cr
\tikzmark{varrowtop} 0 & 0 & 0 & 0 & 1 & 1 \cr
1 & 0 & 0 & 1 & 1 & 1 \cr
2 & 0 & 0 & 1 & 1 & 0 \cr
3 & 0 & 0 & 1 & 1 & 0 \cr
\tikzmark{varrowbottom}4 & 0 & 0 & 0 & 0 & 0 \cr
}
\]
\tikz[overlay,remember picture] {
\draw[->] ([yshift=3ex]harrowleft) -- ([yshift=3ex]harrowright)
node[midway,above] {\scriptsize DAG};
\draw[->] ([yshift=1.5ex,xshift=-2ex]varrowtop) -- ([xshift=-2ex]varrowbottom)
node[near end,left] {\scriptsize $Ca^{2+}$};
}
\end{document}
Instead of using the title key, I would use xlabel, since that's what you're trying to get and it gets the position right (the fact that the title overlaps the labels is a bug though, I'll file a report).
For printing the names on the right-hand side of the axis, you could use extra y ticks, with every extra y tick/.style={yticklabel pos=right, yticklabels from table={data.dat}{Name}}.
A different approach would be to use nodes near coords to place the names near the bars. For this, you have to set point meta=explicit symbolic in the axis to tell pgfplots not to use the x value for the labels (explicit) and to switch off the number parser for the meta data (symbolic), and meta=Names in the \addplot table options. To position the labels to the right of the bars, you can use every node near coord/.append style={anchor=west}.
