12.8.3 Inspect selected element
12.8.3.1 Detail
When an element of the main plot is selected, its detailed information is shown in a table. Further detailed are presented in Annex A15.1 with respect to CDMA network, Detailed of voice users, cell.
12.8.3.2 Event Vectors
You are able to investigate some intermediary output vectors resulting from the cellular simulation.
For the position information (x,y) of the active UE details, all coordinates are always shown in the SEAMCAT coordinate system which by definition either the VLT or the victim reference cell in (0,0). Therefore, the position of the elements of an interfering CDMA or OFDMA system is based on the victim reference cell and not its "internal" reference cell.

12.8.3.3 Plot settings
The plotting options control how the system is shown in the main plot area and how you select elements from the system. This potting option can be seen on the overview page Figure 270.
You can zoom in and out by using either the mouse wheel or the Zoom Factor slider. When clicking on a displayed item SEAMCAT tries to match the coordinates of the click to a cellular element – selecting the first matched item.
When SEAMCAT tries to match the click to an element it allows for a certain amount of uncertainty when matching the coordinates. This uncertainty is also called click radius to illustrate the effect of the actual click point being in the centre of a circle used to search for CDMA elements. You can adjust the “click radius” and in combination with the zoom this allows for all elements to be selected using the algorithm supplied above.
It is often the case that an element different than desired or no element at all is selected when clicking the plot. This problem is resolved by zooming in and possibly changing the click radius.
