System also provides a way of tracking the values of metrics as a system. When metrics are connected to data with time-varying values, System displays the current value alongside the most recent previous value and the percent change between the values. When the values and recent changes are examined for systems of related metrics, you get richer context to consider the data. While depictions of changes in value can be found in many places (economic indicator reports, health records, etc.), this feature is designed to show you systems of changes in the data that are used to measure our world. Since System shows you the statistical direction of the relationships between metrics (though not necessarily the causal direction), this feature can help you predict changes in metrics before they are actually measured and consider possible actions to take to move metrics.
