Apple heath app respiratory

I, too, would like to know what these different colors and gaps in the vertical bars mean. Is there a legend? I have searched the internet but have not yet found an explanation.

As mentioned above, I am using Apple's Health App that comes standard with iOS and features respiratory measurements.

I understand the nature of gaps due to sampling in digital circuits. Digital circuits sample sensors based on a sequence of particular edges of a sampling clock. The edges come at regular intervals and are NOT continuous. The clock rate must meet the conditions of Shannon's Theorem and the Nyquist frequency in order to sample enough to reasonably recreate the sampled signal. Nevertheless, the sampled signal is not sampled continuously which would imply a clock with infinite number of edges per any unit time.

That's why there are gaps relative to time.

What the Apple Health App is showing are also multiple data values and gaps in the vertical direction, at discrete points of time. It is these vertical values and gaps that we are asking about. My latest speculation is that Apple is attempting to "collapse" multiple measurements taken at several clock edges and lumping them at less frequent clock edges. Is that correct?

Also, others have asked about the blue versus grey VERTICAL bars as shown in the figures above. What do the difference in colors represent?

Kind regards,

Which app are you using for this?

The Respiratory app operates by consistently monitoring the respiratory rate, which is often denoted as breaths per minute (br/min). This continuous measurement allows for accurate and real-time tracking of an individual's breathing pattern. As a result, the data captured by the app provides a comprehensive and up-to-date representation of the user's respiratory activity.

When the respiratory rate is measured discretely, the chart that displays this data will accurately reflect the discrete measurements taken over specific time intervals. In this context, discrete measurements refer to periodically recorded values at distinct points in time. Consequently, the chart would show a series of data points, each corresponding to a particular measurement of respiratory rate captured during those intervals.

On the other hand, the app's continuous measurement approach captures a stream of data points over time, without any gaps or interruptions. This results in a smoother and more continuous representation of the respiratory rate on the chart. The advantage of continuous monitoring is that it provides a more detailed insight into the user's breathing patterns, highlighting fluctuations, trends, and changes that might otherwise be missed in a discrete measurement setup.
