description of the key elements in the graphing area:

type of data reading (humidity, tempera-
ture, voltage or current).
Header bar Indicates the date and time of latest read-
ing; the time zone is based on the time
zone setting of the PC running the
browser.
Numerical display area Displays most current data value in units
being measured, as defined by the user.
Graph area A graphical representation of data history
is displayed here.

use Internet Explorer 6.0, you can only

browsers will show the last 1000 points).
