Graphical Representation Of The Frequency Distribution Of Events In The Histogram

The histogram in the Histogram bar illustrates the distribution of event frequency and thus provides a quick overview of the events of one or more cameras.

To open the Histogram bar, click on the dark gray ribbon on the right margin of the MxMC . To begin with, the histogram always shows the entire range of the events logged by the camera.

Structure Of The Histogram
The histogram is split into the overview area on the left and the zoomed area of the selected range in the overview on the right. The yellow scroll bar in the overview area shows the range that is displayed in the zoomed area. Click on  to set the displayed time range in the zoomed area (for example, six hours or one day). If you have set the zoomed area to "Custom," you can modify the displayed time range by dragging the edges of the scroll bar.
If you want to see only events in the zoomed area that have triggered recordings, click on .
The pink area indicates the time range for which recordings exist for the logged events.


Note
The range of logged events may reach farther back than the recordings.

Displayed Time Range

The timestamps at the top and bottom of the histogram show the first and the last of the available events logged by the camera, respectively. You can change this range manually. A small cross at the left of the time range indicates that it has been changed manually. Click on the cross to reset the timestamps to their original values.

Filter Feature

You can filter the display by camera, by group or by event type. There two sliders for this purpose: the group/camera slider and the event type slider . To set the filters, move the sliders until you see the desired results.

Distribution Of Frequency
The length of the bars indicates the frequency of logged events per time unit. Click on if you want to examine the distribution of frequency for a specific point in time in more detail. The display switches to a higher resolution.
If you want to get more detailed information on a specific point in time with a high event frequency, click on the interesting spot in the zoomed area or the overview area.
In the Playback view, a red marker is also displayed to indicate the current position.
