4.8.2 Polar Format
Polar format represents the measurement results on the pie chart (See figure 4.13). The
distance to a measured point from the graph center corresponds to the magnitude of its
value. The counterclockwise angle from the positive horizontal axis corresponds to the
phase of the measured value.
Figure 4.13 Polar format
The polar graph does not have a frequency axis, so frequency will be indicated by the
markers. There are three types of polar formats depending on the data displayed by the
marker. The traces will remain the same on all the graphs.
