matlab - 在 Matlab 中绘制外轴

Question

如何使用 MATLAB 在轴外绘制一些东西？我想绘制类似于此图的东西；

谢谢。

Answer 1

这是使用两个轴的一种可能的技巧:

%# plot data as usual
x = randn(1000,1);
[count bin] = hist(x,50);
figure, bar(bin,count,'hist')
hAx1 = gca;

%# create a second axis as copy of first (without its content), 
%# reduce its size, and set limits accordingly
hAx2 = copyobj(hAx1,gcf);
set(hAx2, 'Position',get(hAx1,'Position').*[1 1 1 0.9], ...
    'XLimMode','manual', 'YLimMode','manual', ...
    'YLim',get(hAx1,'YLim').*[1 0.9])
delete(get(hAx2,'Children'))

%# hide first axis, and adjust Z-order
axis(hAx1,'off')
uistack(hAx1,'top')

%# add title and labels
title(hAx2,'Title')
xlabel(hAx2, 'Frequency'), ylabel(hAx2, 'Mag')

这是之前和之后的情节:
