Progress Telerik UI for Blazor

Area Chart

  • Blazor Area Chart Overview

    An Area Chart represents the change in a one or more values over time and is great fit for both Blazor WebAssembly (WASM) and Server-side dashboard applications. Areas in the chart are created by plotting a series of data points over time, connecting those data points with line segments, and then filling in the area between the line and the x-axis with color.

    Example of Blazor Area chart.

  • Area Chart Data Binding

    The Area chart is a data bound component which also provides the flexibility to bind axes and series to various data sources separately or together.

  • Customizing Area Chart Elements

    You can customize all aspects of the Area chart – from the series color and opacity, to its labels content, font, size, position, line styles and even missing values.

  • Area Chart Line Type

    The Area chart supports different styles for the lines between its data points – Normal (straight line), Step (horizontal and vertical lines) and Smooth (fitted curve).

  • Area Chart Date Axis

    The Area chart supports displaying dates on the x-axis which aggregates the data points that fall within its scope to a single data point that gets rendered.

  • Area Chart Multiple Axes

    The Area Chart can render more than one axis in each dimension and you can associate each series with its own axes. This lets you associate data series with different axes, and position them to the left, right, top or bottom of the chart.

  • Stacked Area Chart

    The Area chart lets you stack different series in one data category on top of each other to showcase cumulative effects.

    Example with chart stacked series in Blazor.

  • Area Chart Missing Values

    If some values are missing from the Area series data, you have options to configure how those missing values to be visualized by the component:

    • Zero (the line goes to 0 value mark)
    • Interpolate - the line will go through the interpolated value of the missing data points and connect to the next data point with a value.
    • Gap - behaves the same way as Zero because a line chart cannot have a gap in its filled area.
  • Combining Area Chart with Other Chart Types

    You can also mix different types of series in a single chart to create more compelling visuals – such as column charts and line charts, or area charts.

  • Area Chart Rendering Modes - Canvas/SVG

    The Area 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.

  • Area Chart Globalization

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

  • Area Chart Theming

    The Telerik Blazor Area Chart component has several built-in themes such as Default (our own styling), Material (based on the Material Design guidelines) and Bootstrap (which looks like the Bootstrap styling to integrate better). 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.
