The values are shown in the following colors:
￭ Blue, if the value has been assigned automatically by a method.
￭ Black, if the values have been entered manually.
￭ Orange, if the values are outside the warning limits.
￭ Red, if the values are outside the intervention limits.
If the warning or intervention limits are breached, then the line number
will also be shown with an orange and red background, respectively.
Assignment date
Date and time of value assignment.
Assignment method
Name of the method with which the value assignment was carried out. If
the values have been entered manually, then manual will be shown here.

who entered the values manually. If the login function was not used, then
the user logged in under Windows will be entered automatically.

the history table, the values are shown in different colors:
