7.2 Data Analysis: Longterm Recordings
Double-click the appropriate log file for analysis. For longterm recordings the follow-
ing window will open (check capter 7.2 for 9 point measurements) :
Plotted Data Window
Units of measurement appear on the corresponding channel window on the left and
are not indicated on the y-axis. The different plots are colour coded. This allows for
different 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 ap-
pear. 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 standards for building biology
measurements (SBM2008): 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 corresponding to the unit of the selected (= bold) chan-
nel. It will be bold for the one and regular for the other, equalling the markings in the
"Statistics/Channels" window.
Navigation within the Plotted Data
Within the plotted data you can easily navigate using a mouse and its scroll wheel.
Move the mouse pointer into the data plot. The scale of the x-axis will be
 zoomed in when scrolling up or by using the "Up Arrow", zoomed out when
scrolling down or by using the "Down Arrow"
 centered around the clock time indicated by the position of the mouse
The data area can be repositioned on the x-axis by a left mouse click hold and drag
left or right. You may just as well use the "right" and "left" arrows of the keyboard.
Zooming of the time on the x-axis is also possible via the "View" menu.

 The far left column labelled "Channels"
displays statistic evaluations of the plot on
the right (in real-time)
 The large area on the right shows the plot
of the collected data over time.
 The "x" (horizontal) axis of the plotted da-
ta is the time scale and the "y" (vertical)
axis shows the units of measurement cor-
responding to the field of measurement.
