##### `rawbg` (Raw BG)
Calculates BG using sensor and calibration records from and displays an alternate BG values and noise levels. Defaults that can be adjusted with [extended setting](#extended-settings)
* `SMOOTH` (`false`) - If `SMOOTH` is false, rawbg will be calculated such that it exagerates direction changes to provide early visible indication of glucose trend changes.
* `UNFILTERED` (`false`) - If `UNFILTERED` is false, rawbg will be calculated using the raw filtered value. If `UNFILTERED` is true, rawbg will be calculated using the raw unfiltered value.
* `DISPLAY` (`unsmoothed`) - Allows the user to control which algorithm is used to calculate the displayed raw BG values using the most recent calibration record.
* `unfiltered` - Raw BG is calculated by applying the calibration to the glucose record's unfiltered value.
* `filtered` - Raw BG is calculated by applying the calibration to the glucose record's filtered value. The glucose record's filtered values are generally produced by the CGM by a running average of the unfiltered values to produce a smoothed value when the sensor noise is high.
* `unsmoothed` - Raw BG is calculated by first finding the ratio of the calculated filtered value (the same value calculated by the `filtered` setting) to the reported glucose value. The displayed raw BG value is calculated by dividing the calculated unfiltered value (the same value calculated by the `unfiltered` setting) by the ratio. The effect is to exagerate changes in trend direction so the trend changes are more noticeable to the user. This is the legacy raw BG calculation algorithm.
##### `iob` (Insulin-on-Board)
Adds the IOB pill visualization in the client and calculates values that used by other plugins. Uses treatments with insulin doses and the `dia` and `sens` fields from the [treatment profile](#treatment-profile).
