TdxChartCrosshairSnapToPointMode Enum

Enumerates available series point targeting modes for crosshair lines in XY diagrams.

Declaration

TdxChartCrosshairSnapToPointMode = (
    Argument,
    Value,
    NearestToCursor
);

Members

Name Description Example
Argument

Default. Crosshair Cursor targets a series point near the vertical line that crosses the mouse pointer position within the diagram area.

Note

Argument and value lines switch places in an XY diagram whose Rotated property is set to True.

This mode is compatible with all possible SnapToSeriesMode and StickyLines property values.

VCL Chart Control: Snap by Argument Mode

Value

Crosshair Cursor targets a series point near the horizontal line that crosses the mouse pointer position within the diagram area.

Note

Argument and value lines switch places in an XY diagram whose Rotated property is set to True.

This mode is compatible with all possible SnapToSeriesMode and StickyLines property values.

VCL Chart Control: Snap By Value Mode

NearestToCursor

Crosshair Cursor targets a series point near the mouse pointer position within the diagram area.

The SnapToPointMode property setter updates SnapToSeriesMode and StickyLines property values when you enable the NearestToCursor mode because it is incompatible with single-line point targeting modes:

VCL Chart Control: Snap to the Nearest Series Point Mode

Remarks

Different snap to point modes allow you to change how the Chart control detects target series points for crosshair lines and the crosshair label.

Note

TdxChartCrosshairSnapToPointMode is a scoped enumeration type. Use the type name together with a scope resolution token (. in Delphi or :: in C++Builder) followed by an enumeration value to refer to this value. For example, use TdxChartCrosshairSnapToPointMode.NearestToCursor (in Delphi) or TdxChartCrosshairSnapToPointMode::NearestToCursor (in C++Builder) to refer to the NearestToCursor value in code.
