EM.CUBE's field plots are interactive. When you move the mouse over a field plot, tiny dots appear on its surface. These dots correspond to the points on the sensor plane where the field data have been calculated. Upon mouse-over, you can highlight one of these points. A small tooltip appears on the plot that shows the field value at that point. In other words, you can read the plot values using mouse-over. The legend of a field plot also shows the minimum and maximum field values, the field unit (V/m for electric and A/m for magnetic) as well as the mean field and the standard deviation.

EM.CUBE offers two different ways of visualizing electric and magnetic fields: as a confetti plot or a cone plot. The first type is a scalar intensity plot and shows the field amplitude and phase using small colored pixels whose size is depends on the total size of the sensor plane and its number of samples. The second type is a vectorial plot showing cones (or arrows) 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 '''Confetti''' or Cone. In the latter case, you can set the size of the vector cones using the box labeled '''Max Size'''. You can set the plot type at the time of defining the field sensor before running the PO simulation. You can also change the plot type afterwards and switch between the confetti and cone types back and forth.

Similar to current distribution plots, field plots (total, magnitude, phase, etc.) are displayed with some default settings and options, which can be further customized individually. To do so, open the '''Output Plot Settings''' dialog by right clicking on a specific plot entry in the Navigation Tree and selecting '''Properties...''' or by double clicking on the surface of the plot's legend box. The settings are identical to those of current distribution plots. Two scale options, linear and dB, are available. You can also change the lower and upper limits of the individual field plots as well as their color map.
