Hello Everyone,
Happy new Year! To begin with. My question is i am using ginput and trying to acquire data of a plot. But the issue i am facing is when i try to aquire data between two selected points it gives me data through out the plot where the (find data points) condition is met rather then just between the selected points. Any help would be appreciated. Have attached my code, data file and also the figure for better understanding.
Thanks
Anand
[filename,pathname] = uigetfile('*.xlsx');
fullfilename = fullfile(pathname,filename);
A = xlsread(fullfilename);
Torque = movmean(A(:,1 ),50);
Angle = movmean(A(:,2),50);
plot(Torque);
[a,b] = ginput(2);
str1 = b(1);
fin1 = b(2);
i = find(Torque > str1 & Torque < fin1);
Torque1 = Torque(i);
Angle1 = Angle(i);
T = table(Torque1,Angle1);

Maybe you mean:
startingIndex = a(1);
endingIndex = a(2);
x = 1 : length(Torque);
mask = find(x >= startingIndex & x < endingIndex);
Torque1 = Torque(mask);
Angle1 = Angle(mask);

Thanks a lot. Learnt my mistake was i wasn't assigning it to variable x which count of Torque and then have it index.
