我有4x1的數字繪圖,1繪製上半部分。我正在用相對高分辨率的1600x1200顯示器觀看它,所以Matlab應該沒有問題可以適應。考慮到我有一個4x2的數字,Matlabs適合一切正常的情況,這尤其奇怪。Matlab:子圖的標題與上面的軸標籤重疊

那麼,什麼是與4X1情節的問題,如何解決?爲什麼Matlab(2016b)無法爲它做什麼它可以爲4x2?從「battery_discharging.txt」

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)))); 

第20個數據集應該足以讓代碼運行。

@SardarUsama這個代碼是兩個最小的,完整。並有問題地創建數字的必要條件。我還包含了一些需要放置一個名爲「battery_discharging.txt」的文件的數據。你還錯過了什麼? –

什麼是'bat_voltage'?當我在小得多的屏幕上運行腳本時(使用2017a),我看不到這個問題。 – EBH

我不知道是什麼原因導致這個問題,不能複製,但我認爲最簡單的解決方法是將得到第一軸的手柄:

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

,並且完成了他們密謀後,將他們一點了:

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

下面我就把它們抱了2%,但你可能需要更多一點。此外,通過同樣的方式,你可以把最後一個軸少許下降:

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