A line polar chart plots connected data points on a radial coordinate system where the circular x-axis represents angles and the radial y-axis represents values. Setting a line series to unclosed mode prevents the endpoints from connecting, which is useful for displaying partial-range functions.
This sample demonstrates an unclosed line contour representing the function y = 0.1x. The x-axis spans 0 to 100 with ticks every 10 units, and the y-axis auto-ranges from 0 to 10 with an interval of 2. Markers are enabled on each data point so individual values are easy to inspect via the tooltip, and the x-axis labels are formatted with decimal notation.
