  • TdxChartCrosshairSnapToSeriesMode Enum

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

    Declaration

    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.

    VCL Chart Control: The Nearest To Free Line Mode

    NearestToCursor

    Crosshair Cursor targets only the series point nearest to the mouse pointer.

    This mode is compatible with all possible SnapToPointMode property values.

    VCL Chart Control: The Nearest To Cursor Mode

    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.

    VCL Chart Control: The All Series Mode

    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.
