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 Radar Column Chart.

The Blazor Radar Column Chart displays the data points on radial lines starting from a common center and act as value axis. The closer the data point to the center, the lower its value. The Radar Column Chart creates triangles for the values instead of rectangular bars like regular Columns Charts do. The Radar Column Chart supports multiple series, so it can be used to visualize comparison between several sets of similar data.

The individual series are marked with different colors that can be customized through the ColorField of the series. The Blazor Radar Column Chart also allows you control the distance between the bars of different series in the same category – use the Spacing property to set your desired distance value. Additionally, you can configure the distance between the different categories though the Gap property.

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 Radar Column Chart that visualizes the nutrient balance of an apple. In this case, the chart uses a single series which represent the nutrient information and a dedicated category for each type of nutrient to visualize their value.

This Chart Radar Column Chart example is part of a unique collection of hundreds of Blazor demos, with which you can see all Telerik UI for Blazor components and their features in action. View the source code of the demos from the library or directly adapt, and edit them and their theme appearance in Telerik REPL for Blazor or ThemeBuilder.
