7.2 Data Analysis: Longterm Recording
Double-click the appropriate log file for analysis. For long-
term recordings the following window will open (check chap-
ter 7.2 for 9 point measurements):

The far left column
labelled “Chan-
nels“ displays sta-
tistic evaluations of
the plot on the right
(in real-time)

The graph shows
the collected data
over time.

The “x” (horizontal) axis of the plotted data is the time
scale and the “y” (vertical) axis shows the units of meas-
urement corresponding to the field of measurement.
Plotted Data Window
Units of measurement appear on the corre-
sponding channel window on the left and are
not indicated on the y-axis. The different
plots are colour coded. This allows for differ-
ent channels to be shown simultaneously.
The x-axis indicates the time span. The figures at the left
and the right end of the grey status line show the times of
start and end of the logging period.
If the status line is mouse clicked, the window on the right
will appear. Here one can enter a preferred time span to
view. The time span can also be selected in the “View”
menu.
The colouring scheme of the plot corresponds to the stand-
ards for building biology measurements (SBM2015):

Green for “no concern”.

Yellow for “slight concern”.

Red for “severe concern”.

Purple for “extreme concern”.
If one selects two channels with different units, the SBM
colour scheme of the plot’s background will be the one cor-
responding to the unit of the selected (= bold) channel. It will
be bold for the one and regular for the other, equalling the
markings in the “Channels” window.
