Constructors
ChartView()
public ChartView()
Properties
Annotations
Gets or sets annotations rendered over the plot area.
public IReadOnlyList<ChartAnnotation>? Annotations { get; set; }
Property Value
IReadOnlyList<ChartAnnotation>?
ChartEngine
Gets or sets the chart engine that produces frames for this view.
public ChartEngine ChartEngine { get; set; }
Property Value
Composition
Gets or sets the composition blueprint describing pane layout.
public ChartComposition? Composition { get; set; }
Property Value
Input
Gets the shared input control handling pointer and keyboard events for chart interactions.
public InputControl Input { get; }
Property Value
IsLoopEnabled
Enables or disables the internal animation loop on the surface view. When disabled the chart relies on the engine scheduler to request frames.
public bool IsLoopEnabled { get; set; }
Property Value
Legend
Gets or sets an optional legend definition rendered on top of the chart. When null, a default legend is built from the frame metadata.
public LegendDefinition? Legend { get; set; }
Property Value
OwnsEngine
Gets or sets whether the view disposes the attached
public bool OwnsEngine { get; set; }
Property Value
RenderParameters
Gets or sets render parameters (dimension, background) forwarded to the underlying surface view.
public RenderParams RenderParameters { get; set; }
Property Value
RendererOptions
Gets or sets the renderer options applied to the GPU surface view.
public RendererOptions RendererOptions { get; set; }
Property Value
Theme
Gets or sets the theme used for axis, grid, legend, and annotations.
public ChartTheme Theme { get; set; }
Property Value
