6.4.2 SWITCHING BETWEEN REAL-TIME AND HISTORICAL VIEWS
By default, Compare page shows real-time relative measurements for currently connected devices. In order to
freeze the comparison at a specific moment in time, it is necessary to switch from Real-time to Historical view
using the right panel on the Compare page:
Figure 6.8: Clicking on the Real-time toggle button changes
the view to Historical
Once the Historical view is selected, the date/time input textbox is enabled for input, and a date/time picker
control is shown for easier mouse selection. As the time is modified either using textbox or the sliders below, data
is retrieved from the server and displayed in the left and central panels.
Note that Real-time view actually displays measurements with a slightly longer delay (30s). Since
communication link between the device and the server can sometimes be slowed down or even
disconnected in unreliable GPRS networks, this delay allows the device to connect again and server to
retrieve missing frames.
6.5 EXPORTING AND DOWNLOADING DATA
To export the data from the cloud storage and download it to your computer, select the Export page from the
navigation menu:
