Figure: Reading current values from a current distribution map by mouse-over.
EM.CUBE offers two different ways of visualizing electric and magnetic current distributions: as a confetti plot or a cone plot. The first type is a scalar intensity plot and shows the current amplitude and phase using colored triangular mesh cells. The second type is a vectorial plot showing cones (or arrows) directed along the visualized current component. In the case of the total electric current distribution, the cone plot shows the overall direction of the currents at any point on the surface of objects. To set the type of a current plot, open the current distribution plot'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 current distribution before running the PO simulation. You can also change the plot type afterwards and switch between the confetti and cone types back and forth.

Current distribution maps are displayed with some default settings and options. You can customize the individual maps (total, magnitude, phase, etc.). To do so, open the '''Output Plot Settings Dialog''' by right clicking on the specific plot entry in the Navigation Tree and selecting '''Properties...''' or by double clicking on the surface of the plot's legend box. Two '''scale''' options are available: '''Linear''' and '''dB'''. With the '''Linear''' (default) option selected, the current value is always normalized to the maximum total current in that plane, and the normalized scale is mapped between the minimum and maximum values. If the '''dB''' option is selected, the normalized current is converted to dB scale. The plot limits (bounds) can be set individually for every current distribution plot. In the '''Limits''' section of the plot's property dialog, you see four options: '''Default''', '''User Defined''', '''95% Conf.''' and '''95% Conf.'''. Select the user defined option and enter new values for the '''Lower''' and '''Upper''' limits. The last two options are used to remove the outlier data within the 95% and 99% confidence intervals, respectively. In other words, the lower and upper limits are set to ? ± 1.96? and ? ± 2.79? , respectively, assuming a normal distribution of the data. Three color maps are offered: '''Default''', '''Rainbow''' and '''Grayscale'''. You can hide the legend box by deselecting the box labeled '''Show Legend Box'''. You can also change the foreground and background colors of the legend box.
