Legend Range Settings

On the 3D View contextual tabs set, on the Display tab, in the Legends group, click the  dialog launcher.

The following settings are available:

Round off legend range and step size

Data is often represented in a decimal form to represent a value accurately. The number of digits after the decimal point could result in a legend range that is difficult to read and interpret.

Select this option for a more legible legend containing rounded off values. The original data range is contained within the rounded off range.

Scale to peak instantaneous values

This option is applicable when viewing the magnitude of a result along with the instantaneous phase. The minimum and maximum value limits (and therefore the colours) remain constant for each phase step. This option makes it simpler to see how the magnitude changes over phase.

Clear the Scale to peak instantaneous values check box when the magnitudes at the given phase are of interest to synchronise the range limits with the displayed data.

Scale to vector magnitude

This option is applicable when comparing two components of a vector with one another. It is simpler to compare relative magnitudes of the components if displayed relative to the same maximum. Use this option to render the components relative to the total vector magnitude. This option allows a relatively small component to be distinguished from a larger component.

Scale to visible results of the same quantity

This option is applicable when a model contains several near field or far field requests. Each request has its minimum and maximum value. For multiple results on a view, POSTFEKO display the data relative to the minimum and maximum found over all the results added to the view. Deselecting this option renders each result according to its minimum, and maximum value.

Scale only to selected frequency

This option is only enabled when discrete frequency data is available in the model. The range limits are determined by the minimum and maximum values found over all the calculated frequency points. For example, it is more convenient to view the change in far field gain over frequency when the far field is scaled according to the maximum / minimum found over all calculated points.

Scale only to selected time step

This option is applicable for time domain analysis where the range limits are determined by the minimum and maximum values of the displayed data for a selected time signal sample.

Scale to request slice dimensions

This option is applicable when the range values are to be determined by the displayed slice¹.
