I have 2 rows data as follows :
STA0 =
'0 -> 2 1.000000 1.000200 A-MPDU 1.000000 1.000100 SUCCESS 1.000100 1.000200 FAIL NO'
'0 NO NaN 1.000270 1.000570 BACKOFF NaN NaN NO NaN NaN NO NO'
I want to make graph in Matlab like this :

So far I only can make graph when only one row exists thus Backoff rectangle doesn't exist.

How to make these 2 rows can be drawn as graph above ?
