Class

ChartZoomableSelection

Declaration

public ChartZoomableSelection()

Declaration

[Parameter]
public RenderFragment ChildContent { get; set; }

Property Value

Controls whether selection-based zooming is enabled for precise chart area examination and data analysis. When set to true, users can drag to select a rectangular area and zoom into that specific region for detailed data exploration. Set to false to disable selection zooming while maintaining other zoom methods like mouse wheel zooming. Selection zooming provides precise control over the exact chart area users want to examine for focused data analysis.

Declaration

[Parameter]
public bool? Enabled { get; set; }

Property Value

Specifies a keyboard key that must be pressed to activate selection-based zooming for controlled user interaction. Use this property to prevent accidental zooming by requiring a modifier key like Ctrl, Shift, or Alt during selection. Key modifiers help distinguish between zooming and other chart interactions like data point selection or tooltips. See ChartZoomableSelectionKey for available keyboard modifiers and their appropriate use cases for different interaction patterns.

Declaration

[Parameter]
public ChartZoomableSelectionKey? Key { get; set; }

Property Value

Specifies which axis should be locked and excluded from selection-based zooming operations for controlled data exploration. Use this property to restrict selection zooming to specific axes while keeping others fixed for comparative analysis or maintaining context. For example, lock the X-axis to maintain time scale while allowing Y-axis selection zooming, or vice versa for focused analysis. See ChartAxisLock for available axis locking options and their use cases in different chart interaction scenarios.

Declaration

[Parameter]
public ChartAxisLock? Lock { get; set; }
