如何通过 Matlab 轴显式显示这些轴表达式？

Question

差异条件：如何改变axis expressions to axes；图轴的隐式处理导致不稳定的条件等图表绘制在错误的数字中，...
函数axis是一个shorthand用于简化修改

The axis (not axes) function provides simplified access to commonly used properties that control the scaling and appearance of axes.

不稳定的代码

hFig2=figure(hFig2); 
hax2=axes(hFig2); 
plot(u); 
axis xy;
axis([0 (size(u,1)/1 - 0) min(u) max(u)]); 
axis off;

用于稳定它但语法错误的伪代码

hFig2=figure(hFig2); 
hax2=axes(hFig2); 
plot(u, hFig2); 
axis('xy', hFig2);
axis([0 (size(u,1)/1 - 0) min(u) max(u)], hFig2); 
axis('off', hFig2);

错误

Error using message
In 'MATLAB:axis:UnknownOption', data type supplied is incorrect for parameter {1}.

Error in axis (line 204)
                error(message('MATLAB:axis:UnknownOption', cur_arg));

Error in code_1s (line 563)
    axis('xy', hFig2);

文档：axis, axes

Answer 1

axis 对特定 axes（或 axes 对象的数组）进行操作 而不是 一个 figure。如果您希望它稳定并将 axis 应用于特定 axes，只需将 axes 句柄作为第一个输入传递给 axis

axis(hax2, 'xy')
axis(hax2, [0 (size(u,1)/1 - 0) min(u) max(u)])
axis(hax2, 'off')
