Blazor Polar Chart visualizes data in terms of values and angles. It provides options for visual comparison between several quantitative or qualitative aspects of a situation. It supports interactive features such as selection and tooltip.

Inversed axis

Reverses the axis labels and ticks. This swaps the higher and lower ranges of an axis. You can rotate the data label by its given angle.

Start angle

Customize the start angle of the chart to rotate it.


Marks data points with built-in shapes such as circles, rectangles, ellipses, vertical lines, horizontal lines, diamonds, triangles, pluses, crosses, and pentagons. In addition to these shapes, use images to make the point more attractive.

Data label

Data labels display information about data points. Add a template to display data labels with HTML elements such as images, DIV, and spans for more informative data labels. You can rotate a data label by its given angle.

Chart types

Supports different types of series like line, column, spline, range area, scatter, and stacked area.

Wind Rose Chart

You can compose the wind rose chart with the help of stacked column series in polar and radar charts.
