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 Area Chart.

Blazor Area Chart is suitable for displaying quantitative data as continuous lines that pass through points defined by their items' values. The portion of the graph beneath the lines is filled with a particular color for each series. The different colors in an Area Chart are useful for emphasizing changes in values from several sets of similar data. The Blazor Area Chart supports multiple series and exposes various configuration options.

The individual series are marked with different colors that can be customized through the ColorField of the series. Additionally, you can control the transparency of the series through the Opacity parameter.

The Blazor Area Chart allows you to configure the type of the series line. By default, the Area Chart will draw a straight line between data points. You can change that to Step or Smooth option.

Occasionally, some values can be missing from the series data. The Blazor Area Chart lets you customize how these missing points will be handled. The MissingValues property of the series supports three options to configure the chart behavior related to missing points – Zero, Interpolate and Gap.

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

The demo showcases a Blazor Area Chart visualizing the gross domestic product growth of three countries. The Chart uses a dedicated series for each of the countries to represent their GDP growth per year category.
