The plots of findpeaks() and original signal have different x axes scales,hence I am unable to overlay one on top of the other. Any help with this will be greatly appreciated!

They actually do not have different scales. (We do not have your code, so I am guessing here.) The locations of the peaks returned by findpeaks are indices unless you gave it the x-vector as an argument. You can get the x-axis values with the appropriate reference.
Example —
[pks,locs] = findpeaks(y);
x_peaks = x(locs);
figure(1)
plot(x,y, x_peaks,pks,'pg')
grid
See if that does what you want.
