TdxChartCrosshairSnapToSeriesMode Enum

Enumerates available snap to series modes for crosshair lines in XY diagrams.

Declaration

Delphi

TdxChartCrosshairSnapToSeriesMode = (
    NearestToFreeLine,
    NearestToCursor,
    All
);

Members

Name	Description	Example
NearestToFreeLine	Crosshair Cursor targets only the series point nearest to the crosshair line that follows the mouse pointer. The SnapToSeriesMode property setter updates the SnapToPointMode property value from NearestToCursor to Argument when you enable the NearestToFreeLine mode because it is incompatible with the point-based targeting mode.
NearestToCursor	Crosshair Cursor targets only the series point nearest to the mouse pointer. This mode is compatible with all possible SnapToPointMode property values.
All	Default. All series in a diagram can be targets for Crosshair Cursor. An XY diagram can display multiple sets of crosshair lines and highlight multiple series points in this mode. Note An XY series can be a Crosshair Cursor target only if the ToolTips.Enabled property is set to True for the series. This mode is compatible with all possible SnapToPointMode property values.

Remarks

Different snap to series modes allow you to change how the Chart control detects target series for Crosshair Cursor. An XY series cannot be a Crosshair Cursor target if the ToolTips.Enabled property is set to False for the series.

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.
