hello guys, I have a data like this and I want to set a upper and lower threshold values(different) for both the subplots seperately, can anyone help me with the code? Thanks in advance!!

What do you intend by ‘threshold’?

Please describe in a bit more detail what you want to do.

Perhaps do you mean y limits instead of threshold? Like how you'd set with the ylim() function?

yeah for both the channels I need only the signal that is greater than 0.0005(y-axis limit) in this case in both the subplots.

The easiest way to define the y-axis limit for each subplot:

YL1 = get(subplot(2,1,1),'YLim')
set(subplot(2,1,1), 'YLim',[5E-4 max(YL1)])
YL2 = get(subplot(2,1,2),'YLim')
set(subplot(2,1,2), 'YLim',[5E-4 max(YL2)])

These go after the subplot calls in your code.

This looks a bit redundant, but guarantees that the correct value for the maximum is set in each subplot.
