好吧,简单来说,我的代码给出了下面的图表。
但我想要的是类似图 30 的东西(第 56 页,高级工程数学,第 9 版,Irvine Kreszig 著)。
\ssfamily
刻度标签的字体、axis label
位置以及更多一点的空间。
前言:
\usepackage{xcolor}
\usepackage{pgfplots}
\pgfplotsset{compat=newest}
\pgfplotsset{small, every non boxed x axis/.append style={x axis line style=-},
every non boxed y axis/.append style={y axis line style=-}}
我的代码:
\begin{figure}
\centering
\begin{tikzpicture}
\begin{axis}[
axis lines= middle,
ylabel=$y$,
xlabel=$t$,
height=100pt,
ymax=3, ymin=-1,
minor y tick num=1,
minor x tick num=1,
restrict y to domain=-20:20,
]
\addplot[
thick,
orange,
domain=0:15,
samples=100,
% fill=orange!60!white,
]
{(3-2*x)*exp(-0.5*x)};
\end{axis}
\end{tikzpicture}
\caption{The sample function, $y=(3-2x)e^{-0.5x}$.}
\end{figure}
抱歉,如果有点长的话。
答案1
这是一次尝试,其中第二组 pgfplotsset{....} 用于设置字体系列,以下两个命令用于重命名\figurename
和编号。
\renewcommand\figurename{Fig.}
\setcounter{figure}{29}
并将 x 和 y 标签位置分配到 (x,y) 处,方法是
ylabel=$y$, y label style={at={(0.05,1)}},
xlabel=$t$, x label style={at={(1,0.3)}},
代码
