RadzenLineSeries<TItem> Class

RadzenLineSeries<TItem>link

A chart series that displays data as a continuous line connecting data points in a RadzenChart. RadzenLineSeries is ideal for showing trends over time, continuous data, or comparing multiple data series. Connects data points with lines, making it easy to visualize trends and patterns. Supports multiple interpolation modes (straight lines, smooth curves, step functions), customizable appearance (color, width, line style), markers at data points, data labels, combination of multiple line series in one chart for comparison, and line styling with different patterns (solid, dashed, dotted). Use CategoryProperty for the X-axis values and ValueProperty for the Y-axis values. Enable Smooth for curved lines, or use Interpolation for more control over line rendering.

Declaration

public RadzenLineSeries<TItem>()

Colorlink

Declaration

public string Color { get; }

Property Value

Interpolationlink

Gets or sets the interpolation method used to render lines between data points. Options include Line (straight lines), Spline (smooth curves), and Step (stair-step lines).

Declaration

public Interpolation Interpolation { get; set; }

Property Value

LineTypelink

Gets or sets the line style pattern (solid, dashed, dotted). Use LineType.Dashed or LineType.Dotted to create non-solid lines for visual distinction or to represent projected/estimated data.

Declaration

public LineType LineType { get; set; }

Property Value

Smoothlink

Gets or sets whether to render smooth curved lines between data points instead of straight lines. When true, uses spline interpolation to create smooth curves. This is a convenience property for setting Interpolation to Spline.

Declaration

public bool Smooth { get; set; }

Property Value

Strokelink

Gets or sets the color of the line. Supports any valid CSS color value (e.g., "#FF0000", "rgb(255,0,0)", "var(--my-color)"). If not set, uses the color from the chart's color scheme.

Declaration

public string Stroke { get; set; }

Property Value

StrokeWidthlink

Gets or sets the width of the line in pixels. Thicker lines are more visible but may obscure details in dense data.

Declaration

public double StrokeWidth { get; set; }

Property Value

Declaration

protected override void BuildRenderTree(Rendering.RenderTreeBuilder __builder)
