各位同仁、各位朋友，大家好！
您能给我一些提示/帮助吗？然后我可以将其用作进一步情节的模板 :)
我有 y 坐标，它们有 25 个值。但是 x 坐标是用 python 列表计算生成的。例如 [i for i in np.argange(0,202,2)]。我该如何处理这个问题？到目前为止，我已经找到了这个问题，但我不知道如何生成“x”坐标。
\begin{tikzpicture}
\begin{loglogaxis}[ xlabel={Degrees of freedom},
ylabel={$L_2$ Error} ]
\addplot coordinates { (5,8.312e-02) (17,2.547e-02)
(49,7.407e-03) (129,2.102e-03)
(321,5.874e-04) (769,1.623e-04)
(1793,4.442e-05)
(4097,1.207e-05) (9217,3.261e-06) };
\addplot coordinates{ (7,8.472e-02)
(31,3.044e-02)
(111,1.022e-02)
(351,3.303e-03)
(1023,1.039e-03)
(2815,3.196e-04)
(7423,9.658e-05)

\addplot coordinates{ (9,7.881e-02)

\end{tikzpicture}
对此，我真的非常感激！
我对标签有疑问：
\begin{axis}[xlabel={Degrees of freedom},
axis lines=middle,
grid=major,
grid style={dashed},
ymax=0.99,xmax=200]
