 During each scan, both the magnitude and the phase of a particular electric field component at a plane are measured. Measured data can easily be interpreted and understood when displayed as 2D or 3D graphs. Visualization of the [[NeoScan]] scan data are realized by LabVIEW based programs. It plots the amplitude and the phase of the measured field distribution on a horizontal plane after the scan.

 In order to view the plots of scan data:
 	Press “Open File 1” button as shown in Figure 5.1. This opens up the dialog window, where direct you to the project in parent folder where you want to open a data file, see Figure 5.2.
 	Choose the desired data file – e.g., E_X_Dir.DAT in project folder patch2.349GHz – and then press “OK” button in the dialog window.
 	“Information Panel” and “Project Description” will display all scan information regarding the selected project and scan (Figure 5.3).
-	Similarly, the user can open file 2, and 3 to display simultaneously.

 	Press “Near Field Maps” tab from [[NeoScan]] Visualization Utility program to view the plots.
 [[NeoScan]] Near Field Maps page displays either 2D or 3D plots of the amplitude and phase distribution of the scanned field from saved files. It includes 2D Plot page and 3D Plot page.

+When you enter “2D Plot” page, 2D contour plots for amplitude and phase distributions of the scanned field are plotted and the maximum and minimum of their values are displayed in the boxes next to the graphs (Figure 5.4).

 	By default, the program plots fields in V/m units. You can use the key labeled “Amplitude Unit?” to display them in dBV/m (Figures 5.4 and 5.5).
 	The “Phase Shift” knob adds an angular shift (in degree) to the phase distribution (Figure 5.6).
 	The Phase Threshold knob will sets any phase below a minimum field threshold (in V/m) to zero. Figure 5.7 compares the 2D Phase graph without a phase threshold (left) with the one with a phase threshold when the minimum field is set to 10 V/m (right).
-	By default, [[NeoScan]] Visualization Utility program fits the 2D graphs into the square window. If the DUT is other than a circle or regular polygon such as square, equilateral triangle, etc. you must choose the “Maintain Ratio” option in “View Fit?” in order to keep the object proportional. As an illustration, Figure 5.8 presents the comparison of 2D amplitude plots for field distribution of a 12 mm × 220 mm (rectangular) slotted waveguide antenna with different view options when “View Fit?” key is set to “Fit to Window” (left plot) and when “Maintain Ratio” option is chosen (right plot).

 	Press “Save Graphs” button to save all plots. The plots associated with a project are saved in a folder called “Plots” within the same folder.
