4 Data Analysis
In General view, the user may access a quick preview of waveform and/or event. But the view
of the measurements is not available. After pointing the cursor on an event point
and leftclicking the mouse, the screen displays information about this event
and the waveform (when
recorded with the event - Fig. 50).
Sometimes the graph may be very dense and a single point may have many overlapping
points; in such case placing the cursor over a point displays the event and waveform that were
recorded with the earliest date/time. At the same time, above the selected point, information is
displayed about the number of events or waveforms.
If there are more events in a point, tabs appear
above the graph. The descriptions of tabs
correspond to the type of event or the waveform.
When an even is selected, the displayed waveform is from the beginning of this event.
Use the slider (or the mouse scrolling wheel) to zoom-in the selected area (reduce the time
interval). If you select the dot of an event which has the beginning and end waveform, the
corresponding waveforms will also be selected. Similarly, if the waveforms were recorded after the
averaging period, clicking on the measurement dot
, simultaneously highlights the dot of
accompanying waveform.

4.3.2 Measurements
Pressing Measurements button, changes the window image into the one shown in Fig. 51. In
the bottom part, the program displays parameters that may be analyzed.
The graph shows the dots representing measured parameters over time. In the case of large
amount of data, dots may form a line.
Similar as in case of choosing the analysis time range, three fields are displayed to indicate
the beginning, duration and the end of the selected time range (required time range may be
manually entered). The range of data displayed in the table, may be also reduced using two
sliders S (start) and E (end).
Below the graph, a summary table
is displayed with recorded values of the parameters.
The table shows only the data for the selected time interval.
