4.2.4.3 Files Bar Chart
In this bar chart, the numbers of recorded files are plotted per day. Microphone channels are
distinguished by differently colored bars. By clicking on the respective entries in the figure legend
under the graph, individual microphone channels can be hidden.
Since all WAV files in the monitoring directory are evaluated to create the plot, not only data from the
current acoustical monitoring are incorporated in the figure. In addition, data from past monitorings
may be shown in the plot, if data was not deleted.
4.2.4.4 Activity Image
This image visualizes the number of recorded WAV files per 10-minute interval as colored circles with
different opacity. The opacity increases by 10% for each file. Consequently, the opacity is 100% for 10
or more files of the respective measurement channel within the respective 10-minute interval.
Thereby, the x-axis represents the date and the y-axis depicts the respective daytime when files were
recorded. By clicking on the respective entries in the figure legend under the graph, individual
microphone channels can be hidden.
By applying this graphical evaluation tool, you can easily assess the quality of your recorded data.
Recorded noise will be distributed equally over the whole day, for instance. In contrast, bat calls will
be recorded mainly in times of twilight.
By specifying the geographical <latitude> and <longitude> of the recording location, the daily time of
sunrise and sunset is determined and inserted into the graph.
