暂时更改一幅图纸的轴？

暂时更改一幅图纸的轴？

到目前为止，这就是我出色的作品。看起来不错，但现在我奇迹般地发现有时我需要负 y 轴。然而，简单地将 ymin 和 ymax 添加到有问题的 U_L 图的 \begin{axis} 并不能解决问题。

该怎么办？

谢谢。

答案1

  1. 在我的答案我预料到您的图表只会在第一象限，但扩展提出的解决方案非常简单。相反， pgfplots使用以下内容定义通用样式（图表）：

\pgfplotsset{Diagram/.style={
            axis lines = middle,
    xmax=9,
%    xmin=0,                                % <--- removed
    ymax=1.5,
    ymin=0,
    xlabel = {$t$},
    xlabel style={anchor=west},             % <--- changed
    xticklabel style={font=\scriptsize},    % <--- added
%    ylabel style={at={(0,1)}},             % <--- removed
    ytick=\empty,
    no marks,
    every axis plot post/.append style={very thick, red},
                    }% end of Diagram style
            }% end of pgfplotsset
  1. 您始终可以使用 new 在本地覆盖全局（通用）设置。它仅在 used或as is done in 中\pgfplotssset有效tikzzpicturefigure姆韦以下
  2. 如果一个图中的图表具有共同的附加样式，则在本地定义它是明智的（对于较短的代码），pgfplotsset就像在姆韦以下
  3. 对于刻度标签，您的解决方案最好以通用pgfplots样式定义字体大小

像这样？

编辑： 在某些情况下，你有如下所示的混合图，一些带有负独立变量，一些只有正独立变量，并且在这种混合图中，图的坐标轴对齐并不重要，你可以删除xmin=-1在最后一个图中删除，然后获得以下结果：

在此处输入图片描述

最后一张图的代码是：

...
\begin{tikzpicture}
\begin{axis}[Diagram,
             ylabel = $i_L$, ]
\addplot coordinates {(0,.4)  (3,.7)  (4,.4)  (7,.7) (8,.4) };
\draw [ultra thin, blue, dashed] (0,0.7)  --  (8,0.7) ;
\draw [ultra thin, blue, dashed] (0,.4) -- (8,0.4) ;
\draw [thick, blue, <->] (8,.4) -- (8,.7);
\node [right] at (8,.55){$\Delta i_L$};
\end{axis}
\end{tikzpicture}
