Chart - Pie Chart

Telerik UI for Blazor Chart is a data visualization component which allows you to output graphical representation of your data. It is useful when you would like to utilize modern browser technologies such as SVG or Canvas for interactive data visualizations. The chart supports various numerical, categorical and axis-free types. The current demo focuses on the Pie Chart.

The Blazor Pie Chart displays the data as sectors from a two-dimensional circle. It is practical for displaying data as parts of a whole. The Pie Chart allows using only one series. Therefore, it is not applicable for visualizing comparison of different sets of data.

The Blazor Pie Chart exposes various configuration options. You can alter the default rotation to change the start angle of the series – by default, the first segment starts at the top. The individual segments of the Pie Chart are marked with different colors that can be customized through the ColorField property of the series. The Blazor Pie Chart also allows you to focus a specific segment – the ExplodeField property of the series can be used to set an Exploded Segment that will be visually separated from the rest of the circle with a small margin. You can additionaly configure the segment visibility in the legend.

The main part of the Pie Chart is a circle. Thus, you may need to set both the Width and Height parameters to achieve the desired layout and dimensions. By default, the Chart container <div> expands horizontally to 100% and the height is set to 400px in the CSS theme.

Besides series customization, the Blazor Chart exposes multiple nested tags that allow you configure the rest of the chart elements – Legend, Plot Area, Tooltip. Check the Chart API Reference for a full list of properties, methods and events.

This demo showcases a Blazor Pie Chart that visualizes the Spain electricity production for 2008. There is a category defined for each electricity type and a dedicated segment for each category representing its value.
