I got a Muscle Activity data that Anybody and Emg and try comparison between Anybody and Emg (attached jpg file)

I was normalized by dividing the maximum value of the data.
(Max value was 1)

Anybody is the minimum value is zero, but Emg data have not zero value

Anybody is the minimum value to zero will optionally?
(I would like to know whether performed. When min data value = 0.2, total data -0.2)

Dear Yoonho,

Muscle Activity and EMG are not exactly the same, so they can only be compared roughly. EMG measurements are difficult and often noisy. These offsets in the measurements are not easy to explain. I think your results look very good. It is very difficult to compare EMG and muscle activity. In ANyBody its easier, a muscle is activated or not and muscle activity is in percent to its maximum.

There is some more information on the Wiki:
