I have to very urgently create a spectrum analyser in flash. i have to show the animation using a total of 6 bars. flash computespectrum generates values -1 to +1. so how do i create a bar visualization which can have values within 0 to 100, with these values. i am not a physics guy. please help…

note: i dont want to use bitmapData class. only values for normal scaling in y axis
