I use a Polar OH1 optical heart rate sensor to monitor my heart rate during training. Sometimes it moves/turns around and does not record data for a few seconds resulting in a messy graphical representation.
By fixing the data we can get cleaner graphics
You can download all of your training data from Polar by following this guide:

This might take a while...
After downloading the data put all files into to data folder.
To fix the data run
python main.py
The missing heart rate values are approximated by calculating the mean of the last recorded heart rate before the missing value and the next recorded heart rate after the missing value. This approximation might not be perfect for large gaps with a huge difference in the last and next heart rate value but for our case it is sufficient.
To visualize all training sessions run
python visualize.py -a
If you only want to visualize the data for a specific training session use
python visualize.py --date year-month-day --time hour:minute
You can also change the temporal resolution of the graphic in seconds using resolution -resolution.
