我想制作一个带有边际直方图的散点图，类似于所做的这里，但我希望轴为对数对数。我尝试过这个：
\documentclass[border=5mm]{standalone}
\usepackage{pgfplots}
\begin{document}
\begin{tikzpicture}[
/pgfplots/scale only axis,
/pgfplots/width=6cm,
/pgfplots/height=6cm
]
% The scatterplot
\begin{loglogaxis}[
name=main axis % Name the axis, so we can position the histograms relative to this axis
]
\addplot [only marks, mark size=1.5] table {random.dat};
\end{loglogaxis}
% The histogram for the x axis
\begin{semilogxaxis}[
anchor=south west,
at=(main axis.north west),
height=2cm,
xtick=\empty
]
\addplot [
hist={data=x}, % By default, the y values would be used for calculating the histogram
fill=gray!50
] table {random.dat};
\end{semilogxaxis}
% The histogram for the y axis
\begin{semilogyaxis}[
anchor=north west,
at=(main axis.north east),
width=2cm,
ytick=\empty
]
\addplot [
% For swapping the x and y axis, we have to change a couple of options...
hist={handler/.style={xbar interval}}, % ... use bars instead of columns ...
x filter/.code=\pgfmathparse{rawy}, % ... interpret the x values of the histogram as y values
y filter/.code=\pgfmathparse{rawx}, % ... and vice versa.
fill=gray!50,
] table {random.dat};
\end{semilogyaxis}
\end{tikzpicture}
\end{document}
但是，我明白了：
random.dat
