select multiple segments in the signal

Hello team,

I have below signal with x-axis as time.

I want to select segments as mentioned as T1, T2, and T3 (Orange) times as first and last part of segments.

I would like to select segment based on these T1-1,T1-2 for segment 1 , T2-1,T2-2 for segment 2 and T3-1,T3-2 for segment 3. How to provide these limits T1-1,T1-2 and so on and use that segments for further processing.

Please support.

It is not clear as to whether you already know those limits ahead of time, or if you need to figure out where the breaks are based upon the signal value?

or if you need to figure out where the breaks are based upon the signal value?

And, if so, what is the criterion for where the sections begin and end?

I would to like plot or visualize signal first then user can select limits of his own choice.

Criterion for selection - In this signal we can clearlty see the acceleration levels and provide limits. But i want to show this figure to user first then user can select multiple limits for segments
