The Blazor Pie Chart is a circular graphic, which is ideal for displaying proportional values between different categories. Pie charts support animation and interactive features such as tooltip and selection.

Pie legend

Legends are used to show information about each point, to know about its contribution towards the total sum. You can collapse the point using legend click.

Custom radius

Customize the radius of the pie to change the look and functionality of the Blazor Chart.

Start and end angle

Customize the start and end angles of the Chart to achieve the semi-pie.

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.

Smart labels
