我正在策划这件事
但由于某种原因,我的图表很奇怪:
平均能量损失
\documentclass{article}
\usepackage{tikz}
\usepackage{pgf}
\usepackage{pgfplots}
\begin{document}
\begin{center}
\begin{tikzpicture}
\begin{axis}
[xmin=0,
xmax=80,
ymin=0,
ymax=27.5,
xlabel={$t$},
ylabel={$v$},
grid=both,
grid style={line width=.1pt, draw=black},
major grid style={line width=.2pt,draw=black},
axis lines=middle,
minor tick num=1,
axis x line=bottom,
axis y line=left,
axis line style={-stealth},
ticklabel style={font=\tiny},
yticklabels={0,10,15,20,25},
xticklabels={,10,20,30,40,50,60,70},
ytick={0,10,12.5,15,17.5,20,22.5,25},
xtick={0,5,10,15,20,25,30,35,40,45,50,55,60,65,70,75},
xlabel style={at={(ticklabel* cs:1)},anchor=north west},
ylabel style={at={(ticklabel* cs:1)},anchor=south west}]
\addplot[domain=0:80,red,line width=0.5mm,samples=500] {15*(1-e^(-x/5)) + 10};
\end{axis}
\end{tikzpicture}
\end{center}
\end{document}
你知道为什么会发生这种情况吗?
答案1
由于您并没有真正说明您对当前解决方案不满意的方面,因此我将尝试复制给定的图表。
\documentclass{article}
\usepackage{tikz,pgf,pgfplots}
\begin{document}
\begin{tikzpicture}
\begin{axis}[
width=40em, % (xmax - xmin) / scalingFactorBetweenXAndYAxis
height=22.5em, % ymax - ymin
xmin=0,
xmax=80,
ymin=7.5,
ymax=30,
xtick={0,10,...,70},
minor xtick={5,15,...,75},
ytick={10,15,...,25},
minor ytick={10,12.5,...,27.5},
grid=both,
xlabel={$t$},
ylabel={$v$},
axis lines=middle,
xlabel style={at={(ticklabel* cs:1)},anchor=north east},
ylabel style={at={(ticklabel* cs:1)},anchor=north east},
]
\addplot[domain=0:80,red,line width=0.5mm,samples=500] {15*(1-e^(-x/5)) + 10}; % whatever the correct function is
\end{axis}
\end{tikzpicture}
\end{document}
