current value: two for values greater than 0 and lower than 0.1; one for values
between 0.1 and 100; and none for other cases (and analogously for negative
values).
All these numerical indicators incorporate an additional parameter, Save Log?.
In case of enabling this option (“Yes”), any changes in the value of the indicator
will be continuously saved to an internal log file, so the final user can be
afterwards offered a visual representation that reflects the chronological
evolution of such value. Boxes for which this option has been enabled will show
a small icon overlaid on their upper left corner.
Figure 34 Indicator implementing the Log Function
Boxes showing this icon let the user press them, which will bring up a pop-up
window similar to Figure 35.
Figure 35 Graphical representation of the Log File
The graph (where the vertical scale will dynamically adapt to the values being
represented) shows the chronological evolution of the value, with higher or
lower detail (hourly, daily, weekly, monthly; see Figure 36) depending on the
zoom level set by the user by means of the on-screen magnifying glass control.
In the case of the lower detail levels, the graph will show the average values per
time unit (day or month) as well as the maximum and minimum values.
Finally, the bin icon (lower right corner of the screen) lets the user, by
performing a long press, delete the contents of the log file, thus setting the
values of the monitor to zero.
