[[EM.Cube]] offers two different ways of visualizing electric and magnetic fields: as a intensity plot or a vector plot. The first type shows the field amplitude and phase using small colored pixels. The pixel size is equal to the mesh cell size in the case of [[EM.Tempo]] and [[EM.Ferma]] and it is specified and controlled by user in the case of [[EM.Cube]]'s other computational modules. The second type is a vector plot showing arrows (or cones) directed along the visualized field component. In the case of the total electric and magnetic fields, the cone plots show the overall direction of the fields at any point on the sensor plane. To set the type of a field plot, open the field sensor's property dialog by right clicking its name in the Navigation Tree and selecting '''Properties...''' from the contextual menu. In the Plot Type section, choose one of the two radio buttons labeled '''Intensity''' or '''Vector'''. In the former case, you may also check the box labeled '''Data Interpolation''', which is unchecked by default. This will convert the pixelized confetti map into a smooth intensity plot using data interpolation. In the latter case, you can set the size of the vector arrows using the box labeled '''Max Size''' or set the '''Cone Length Ratio''' and '''Cone Radius Ratio''' with respect to the total arrow length.

You can also choose from three color maps offered in the plot's property dialog: '''DefaultRainbow''', '''RainbowBasic''' and '''Gray Scale'''.

[[EM.Cube]]'s field plots are interactive by default. When you move the mouse over a field plot, tiny dots appear on its surface. This dots correspond to the points on the sensor plane where the field data have been calculated. A small tooltip appears on the highlighted point that shows the field value at that point. In other words, you can read the plot values using mouse-over. For high resolution field plots, the appearance of tiny mouse-over dots may be undesirable.
{{Note|You can turn off 3D plot mouse-over from the Advanced tab of the Preferences Dialog, which can be accessed from the Edit Menu or using the keyboard shortcut '''Ctrl+H'''.}}
