I’m working on a project where I need to visualize ECG and ACC signals from PolarH10. Specifically, I want to plot the signals from the last 10 seconds of data in a small rectangle on an image. To fit the plots within this rectangle, I normalize the data each time I receive a new data packet from Polar. (The polar data is received as packets per seconds depending on the frequency of ACC(200 Hz) and ECG (130 Hz) data).
