A polar chart plots data on a radial coordinate system where each point is positioned by angle and distance from the center. Line series on a polar plot are ideal for visualizing directional sensitivity patterns, mathematical functions, and other cyclical data.
This sample displays three microphone directionality patterns: cardioid (unidirectional), bidirectional, and omnidirectional. Each line series is styled with a distinct stroke dash pattern and generated from trigonometric functions. The x-axis spans -180 to 180 degrees with labels showing absolute values, and the y-axis ranges from -25 to 0 dB. An interactive legend lets you toggle each pattern on and off for focused comparison.
Follow the step-by-step Polar Chart Tutorial to learn how such charts are built. See the Polar Chart documentation for all configuration options.
