我有几个问题我自己无法解决。
- y 轴的标签无法显示在箭头上方/上方
- 然后我无法将 CDF 的 1/100% 放在 y 轴上(甚至手动也不行)——“1”消失了。
- 此外,CDF 在左侧有一个长尾 - 但图形突然停止。
- 右上角有一个“1”,使用 \pagestyle{empty} 不会消失

答案1
我承认我无法从逻辑上解释这y label style
件事,但是你可以这样做:

\addplot[smooth,black,name path=A, tick] gnuplot{\cdf(x)(0)(1)} node[right,pos=0.5, xshift=2ex]{$F$} node[right,pos=0.5, xshift=-12ex, yshift=0.75ex]{$G$};
