的父对象，因此我将每次通过循环删除对
试图模拟真实动态条件的代码
clear all; close all;
hFig2=figure('Units','inches', 'Name', 'Time');
hax2=axes(hFig2);
movegui(hFig2, 'southeast');
index=1;
while (index < 7);
hFig2=figure(hFig2);
u=0:0.01:1+index;
plot(hax2, u); % Give columns 1xXYZ to Matlab
hold on;
axis(hax2, 'xy');
axis(hax2, [0 (size(u,2)/1 - 0) min(u) max(u)]); % to maximise size
axis(hax2, 'off'); % no ticks
index=index+1;
pause(1);
hold off;
drawnow
end;
log 1 hax2在更动态的情况下，日志2 hax2主要在Code
%% Logs 1 in dynamic condition with failure output
% Failure in more dynamic conditions because axes get deleted for some reason
% hax2
%
% hax2 =
%
% handle to deleted Axes
%
%% Logs 2 mostly in Code condition and correct because
% hax2 =
%
% Axes with properties:
%
% XLim: [0 201]
% YLim: [0 2]
% XScale: 'linear'
% YScale: 'linear'
% GridLineStyle: '-'
% Position: [0.1300 0.1100 0.7750 0.8150]
% Units: 'normalized'
hax2即handle to deleted axes由于某种原因失败时出现错误
%% Failure message

% Error using plot
% Invalid handle.

% Error in test_invalid_handle (line 12)
% plot(hax2, u);
若干解决方案的初步建议
- 在每个循环结束时保存
axes句柄;在MATLAB中绘制时保存轴句柄 - …
操作系统:Debian 8.5 64位
Matlab: 2016
硬件:华硕Zenbook UX303UA
Linux kernel: 4.6 of backports
调用axes时，第一个输入应该是指定父对象的参数/值对。如果你给它传递一个单句柄图形输入，它会假设输入是一个axes
axes(hFig2)
% Error using axes
% Invalid axes handle
或者写成
hax2 = axes(hFig2);
% Error using axes
% Too many output arguments.
因为你传递了一个无效的axes句柄给它，它不能正确地将一个新的axes句柄分配给hax2。您看到的已删除的hax2很可能来自先前的脚本运行。
相反，您需要使用参数/值对来指定axes的Parent属性。
hax2 = axes('Parent', hFig2);
另外，由于您显式地指定了每个plot对象
figure的无关调用。
