Hi umair, if I print the trace of bytearray before compress its giving as "A¿A~A¿A" and after compress its giving as "xAsA-XgTSUºA?!ti☺♦A☼↑:QA☼w♦Ac]AcG¶i"5Jo↕►B◄¶A?.A+*A¢A,A H§A:↕jPzA" A A^A,A☼EA?=A§AzsAz↔AzA»Ar↑wA¼?ArA¼A~cdA-A½A-oAr5A¿A1A¿AµA^A£A,YA?A%PA- @↨"
I tried it giving different charts but its giving same bytearray for all those charts. any help ?
