Progress Telerik UI for Blazor

Blazor Pie Chart Overview

A Pie chart component shows how a certain total amount is split between categories as a circle divided into radial slices. Each categorical value corresponds with a single “pie slice” of the circle, and the size of each slice is proportional to the value of the whole. The UI for Blazor Pie chart component works in both Blazor WebAssembly (WASM) and Server-side applications and is suitable for displaying single series of data.

Pie Chart Exploded Segment

You can highlight some of the segments of the pie as “exploded” i.e. separated from the rest of the circle with a small margin. This helps bring attention to them as outliers or as important bits that the viewer should focus on.

Customizing Pie Chart Elements

You can customize all aspects of the Pie chart – from the series color, to its labels content, font, size, position and formatting.
Pie Chart Rendering Modes - Canvas/SVG

The Pie Chart renders in the browser to preserve server resources. It has SVG markup and <canvas> rendering modes to improve performance further, and it can even animate during rendering for a smoother user experience.
Pie Chart Globalization

The Label Format Strings in UI for Blazor Pie Charts, are culture aware so your users see, for example, the expected number formats with the decimal and thousands separators they are used to.
Pie Chart Theming

The Telerik Blazor Pie Chart component has several built-in themes such as Default (our own styling), Material (based on the Material Design guidelines), Bootstrap (which looks like the Bootstrap styling to integrate better) and Fluent (based on Microsoft Fluent UI). Each theme predefines several series colors, so your data is visualized according to your design guidelines. You can further customize any of the out-of-the box themes, style a specific chart component or create new theme to match your colors and branding by using the Telerik SASS ThemeBuilder application.
