12.7 REPRESENTING SINGLE POLAR DATA
To represent the measured data we need to select the Directivity mode in the
Waterfall, Directivity & 3D control panel. Then enter the Directivity Settings dialog
and press the browse button. Entering our data directory we find the situation in
Fig.12.15:
Figure 12.15
The set of files is composed by 73 files; it is sufficient to choose one of them. It is
now important to identify the initial and last files for display, this is done with the Z-
start and Z-stop values to be input as in Fig.12.16. We choose to display all
responses from -180° to +180°, take the response on axis as reference and choose
frequency limits from 150Hz to 15kHz.
Figure 12.16
We are, at last, ready to start a directivity analysis.
The results are in Fig. 12.17 both as color map and 3-D waterfall plot.

Treating polar data we may be more interested in referencing the graph to the
response that our speaker shows on-axis. This is easily done pressing the reference
button and executing the processing again.
