A line polar chart renders connected data points on a radial coordinate system, where the circular x-axis represents angles and the radial y-axis represents values. A single series on a polar plot highlights the shape of one function or dataset without competing overlays.
This sample plots a modification of f(x) = 1.5*sin²(3x) as a single line series loaded from an external CSV file. The x-axis spans 0 to 360 degrees at 30-degree intervals, the y-axis uses a 0.3 tick interval with value stacking, and an alternating radial grid palette makes it easy to read function values across concentric bands.
