Hello,
How to plot 12-leads ECG signal in one figure?
The ECG data are included in the structure:
% Create a structure to hold the ECG data
N = size(rawData,1)
ecgData = struct();
ecg = struct();
% Therefore
ecgData.leadI=rawData(:,2);
ecgData.leadII=rawData(:,3);
% The augmented vector leads and lead III are derived as
% III=II-I; aVR=-(I+II)/2; aVL=I-II/2; aVF=II-I/2
ecgData.leadIII=ecgData.leadII-ecgData.leadI;
ecgData.aVR=-(ecgData.leadI+ecgData.leadII)/2;
ecgData.aVL=ecgData.leadII/2;
ecgData.aVF=ecgData.leadII-ecgData.leadI/2;
ecgData.V1 = rawData(:,8);
ecgData.V2 = rawData(:,4);
ecgData.V3 = rawData(:,5);
ecgData.V4 = rawData(:,6);
ecgData.V5 = rawData(:,7);
ecgData.V6 = rawData(:,1);

You can use the tiledlayout function.

To use the commonly-accepted plot format for a 12-lead EKG —
EKG = rand(12, 30)
EKG = 12×30
