The element implements a dialog of selection the data source, often the archive ones, for the trend formation in the "Graphics group" frame. Selection is provided from the list, specified in the attribute "Select: parameters accessible to select (allowSelLst)" of the frame-initiator. For the selected source you can specify the name, scale, logarithmic scale, dimension and the color of the trend.

In the "Select: parameters accessible to select (allowSelLst)" attribute the data sources should be placed in the following way:
- {DAQ_Arh_addr}[:Name[:min:max[:dim]], where:
  - "DAQ_Arh_addr" — address of the parameter, for the group linking, or address of the attribute with data from the "Data acquisition (DAQ)" subsystem, as well as the address of the values' archive, for example:
    - /LogicLev/experiment/prm_F3 — address of the "F3" parameter ;
    - /DAQ/System/AutoDA/prm_CPULoad/load — address of the "load" attribute of the "CPULoad" parameter;
    - /Archive/va_LC21_1_var — address of the "LC21_1_var" archive.
  - "Name" — name of the source to display. At the group linking the name will be taken from the "NAME" attribute.
  - "min", "max" — display scale. At group linking the scale will be taken from the "min" and "max" attributes, respectively. In the case of the scale absence (min >= max) the auto-scale will be enabled.
  - "dim" — dimension (measuring unit) of the parameter to display. At the group linking it will be taken from the "ed" attribute.
- <varhs> — template of the group selection, if you specify it all available archives in the system will be included into the selection list.
