The menu group contains, in addition to the functions in the toolbar, the items
"Copy", "Save as" and "Load the measurement file".
The processing functions are available both during the processing of archived data
(previously measured files) and when the graphs are displayed online during the
acquisition process.
With the graphs displayed online, the option "Update" can also be enabled – the
graph and the table are respectively supplemented with the newest data at the
acquisition interval pace.
With a graph displayed online, this option is always automatically enabled as long as
no section appears or the automatic mode for the end of the time axis is disabled.
If the update has automatically been disabled by this kind of operation, this option
can only be reactivated by resetting and/or disabling the zoom function.
With the tables displayed online, the update is interrupted independently of the
update of the graph when if the table is browsed and when the newest line is not the
last line shown in the table. The update process continues when you go back to the
last line at the table end.
Update automatically
This option is not available for the presentation of an already archived graph. However, with a
graph displayed online, the newest value is always appended at the end of the time axis. If this is
not desired, the automatic update can be deactivated. On the other hand, the enlargement of the
graph section always causes the deactivation of the automatic update. If the automatic update is
desired again, the option can be reactivated by clicking again on it.
Fixed time axis
Selecting the option "Fixed time axis" always causes the display of only one time interval – defined
for a specific period of time – of the last measurement series. If this period is exceeded, the
oldest measurement series escape left out of the graph while the new measurement series are
appened to the right. The time interval displayed remains firmly stuck on the defined value. It can
be modified under the item "Manual entries". The option can be disabled by simply clicking again
on it. The automatic mode for time axis can be reactivated after confirmation.
