Matlab：子图的标题与上面的轴标签重叠

Question

我有4x1的数字情节，1个情节占据上半部分。我在相对高分辨率的1600x1200显示器上观看它，所以Matlab应该没有任何问题可以适应。考虑到我拥有的4x2数字，Matlabs适合一切正常，这是特别奇怪的。

那么4x1情节有什么问题呢？我该如何解决呢？为什么地球上没有Matlab（2016b）不能为4x2做到这一点？

identifier='unshielded';
bat_discharging=readtable('battery_discharging.txt','Format', '%u%f%f%f');

subplot(4,1,[1 2]);
yyaxis left;
plot(bat_discharging{:,1},bat_discharging{:,2});
ylabel('Voltage, V');
yyaxis right
plot(bat_discharging{:,1},bat_discharging{:,3});
hold on
plot(bat_discharging{:,1},bat_discharging{:,4});
ylabel('Current, A');
hold off
xlabel(bat_discharging.Properties.VariableNames{1});
legend('Voltage', 'Current with external reference',...
    'Current with internal refence', 'Location','east');
title( ['Discharging, ' identifier]);

subplot(4,1,3);
[ext_currentfit,ext_gof, ext_output] = fit(double(bat_discharging{:,1}),...
    bat_discharging{:,3}, 'smoothingspline');
plot(bat_discharging{10:end,1}, ext_output.residuals(10:end));
xlabel(bat_discharging.Properties.VariableNames{1});
ylabel('Current, A');
title(sprintf(...
    'Battery current measurement noise, external reference, %s, span=%.3e, %s=%e',...
    identifier,range(ext_output.residuals(10:end)),...
    '\sigma',std(ext_output.residuals(10:end))));

subplot(4,1,4);
[int_currentfit,ext_gof, int_output] = fit(double(bat_discharging{:,1}),...
    bat_discharging{:,4}, 'smoothingspline');
plot(bat_discharging{10:end,1}, int_output.residuals(10:end));
ylabel('Current, A');
xlabel(bat_discharging.Properties.VariableNames{1});
title(sprintf(...
    'Battery current measurement noise, internal reference, %s, span=%.3e, %s=%e',...
    identifier,range(int_output.residuals(10:end)),...
    '\sigma',std(int_output.residuals(10:end))));

来自“battery_discharging.txt”的前20个数据集 应该足以让代码运行。

x = 1:100;
y = rand(100, 1);

subplot(3,1,[1 2]);
plot(x, y);
xlabel('label');

subplot(3,1,3);
plot(x, y);
title('TITLE');

Answer 1

我不知道是什么导致了这个问题，并且无法重现它，但我认为最简单的解决方案是获得第一轴的处理：

ax = subplot(4,1,[1 2]);

在你完成绘图后，将它们移动一点：

ax.Position(2) = ax.Position(2)*1.02; % This may be adjusted
% subplot(4,1,3); etc...

在这里，我把它们提高2％，但你可能还需要更多。此外，通过相同的方式，您可以稍微减少最后一个轴：

ax = subplot(4,1,4);
% do all the plotting
ax.Position(2) = ax.Position(2)*0.98; % This may be adjusted
