Graph Displaying

The count rate and dose rate graphs display data and are operated in the same way.


If the graph displays the most recent data corresponding to real time, then on the right, in gray, operational data is displayed that was read by the device from its sensor, but was not yet processed (data processing and filtering algorithms need to accumulate a certain amount of data). Already processed and filtered values are displayed on the graphs in green/blue. Live data is stored for the last 10 minutes.

One can control the live data filter that is displayed on the graph. You can set the width of the filtering window in the graph settings, i.e. the time over which the data is averaged. Such averaging is performed by the device, serves only to display operational data and is not related to data processing by the device, as a result of which the values displayed by color graphs are calculated.

On the dose rate graph, vertical colored lines with a circle at the top show the moments when alarms occurred. These lines can be disabled in the graph settings.

Scale selection

The displayed data can be displayed in linear, logarithmic and quadratic scales. The current scale name is displayed at the top left of the graph; it is the square root in the example.

The scale can be changed either explicitly in , which are called by the button
, or by double-tapping the graph. You can set your own scale for each graph.

Y-axis zooming

By default, the displayed plot area fills the entire area visible in the window along the Y axis. The horizontal grid always has 8 cells, and the digitization values are calculated dynamically based on the displayed data. It should be borne in mind that two additional points are involved in determining the maximum and minimum values of the visible area: one beyond the left border of the area and one beyond the right.

You can select automatic scaling along the Y-axis both in the current visible area and in the entire range of data available to the application in the graph settings. Each graph (count rate, dose rate) has its own setting.

Graphs can be moved along the Y-axis (up/down) by swiping your finger across the screen. Initially, to switch from automatic scaling to manual scaling, you need to move the graph up or down vigorously enough (protection against accidental shift during paging). In this case, automatic scaling is disabled, and the graph can be precisely positioned with gestures in order, for example, to find out the values in peaks.

With the pinch gesture on the screen, you can stretch and shrink graphs both vertically and horizontally. When pinching vertically, the auto zoom mode is also disabled.

The “A” button is both an indicator of the current zoom mode and a means of returning to the last auto zoom mode selected. The icon on the button corresponds to the selected mode:
Automatic scaling over the visible area.
Automatic scaling over the entire data range.
Manual zooming. Tapping the button returns to the last autoscaling mode selected in the settings.
Both graphs are present on the screen and their scaling modes do not match. Tapping the button returns the last autoscaling mode selected in the settings for each graph.
There are no rows in this table
In , you can disable the transition to the manual scaling mode. In this case, attempts to shift the graphs and pinch along the Y axis are ignored, and the “A” button is highlighted in red.

X-axis zooming

Scaling of graphs along the X axis (time axis) is performed either by using the buttons
, or a pinch gesture. A long tap of the button increases the zoom to the maximum or decreases to the minimum.


Scrolling graphs horizontally is performed by usual gestures, as well as buttons
. The buttons search for the previous/next piece of data after a break in time.
A long tap of the button moves to the very beginning or, respectively, to the very end of the graph. The data is displayed in certain portions. When the limit is reached, a new piece of data is loaded from the database.
