Dimensional Properties and Rationale

Dimensions	Representational Dimensional Scale	Representing Dimensional Scale	Rationale
Day	Interval	Interval	The CBG values recorded each day are associated with a date that corresponds to the requirements for interval scale in the visualization.
Time	Interval	Ordinal	Points in time itself are interval in scale, however, each of the four-time points in the visualization have only category and magnitude, but do not occur at equal intervals, nor is there an absolute zero value possible since we are still only observing points in time.
CBG	Ratio	Ratio	The values for CBG are all categorical, have magnitude, equal interval, and could potentially have a value of absolute zero.
Insulin	Ratio	Ratio	The values for insulin are all categorical, have magnitude, equal interval, and could potentially have a value of absolute zero.
