An area polar chart fills the region between the line and the center on a radial coordinate system, making it effective for comparing the coverage or magnitude of multiple datasets around a central point. Stacking area series shows cumulative contributions at each angle.
This sample compares the sensitivity patterns of three unidirectional microphones (SMM58, NTT1A, and sE4400a IV) rendered as stacked area series. Data is generated from cosine-based functions across -180 to 180 degrees at 30-degree tick intervals, with the y-axis ranging from -25 to 0 dB. An interactive legend lets you toggle each microphone on and off, and an alternating grid palette aids readability.
