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 simultane-
ously.
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 log-
ging 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
standards for building biology measurements (SBM2015):
Green for "no concern".

Yellow for "slight concern".

Red for "severe concern".

Purple for "extreme concern".

If you select 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) channel. 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
Navigation within the plotted data can easily done with 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, alternatively by using the "right" and "left"
arrows of the keyboard. Zooming of the time on the x-axis can also be
achieved via the View Menu.
Scaling of the y-axis is done automatically by default but can also be
adjusted manually through the View / Scale menu.
