Each instrument includes statistics functions which automatically track its maximal, minimal, and average values.
To see one of these automatically calculated statistical values, you can use the instrument's context menu:
As a default setting, each instrument will show its current value, i.e. the "Show as CURRENT instrument value" option will be selected.
After choosing some statistical values (AVERAGE, MINIMUM, MAXIMUM), the instrument will switch to displaying the chosen statistic value. That will be indicated by an "AVG", "MIN", or "MAX" prefix to the instrument value.
By selecting the "Reset statistical values" option from the context menu, you will reset all statistical values to the current value of the instrument.
After switching instrument display to some statistical values, it will affect all windows attached to the instrument window as well, for example, the instrument value log.
