Polar Charts are the best when we need to show something on a chart of radial type. The point of origin is in the center of the x-axis circle, which radius is the y-axis range; ticks which you can see on x-axis look like beams and all start in the point of origin. Both scales in Polar charts are linear by default. These charts can work with area, line, spline and scatter series. They are usually being used in cases of constructing functions or in any cases when you need to use radial axis.
This Chart is a good sample of using Polar Charts for constructing a function. We’ve got an only spline series here, which somehow represents a function; while values on axes are ranged between 0 and 100 (0) for x-axis and from 0 to 10 for y-axis, the spline takes the categories as arguments of the function. If we look at the tooltips, we will see the argument value in the title and the function value in the tooltip’s body. Looking at the spline and exploring the marked points, we can say that the function should be y = 0.1*x. So, this sample shows you, how to use AnyChart Polar Charts to construct a function.
