XAxisDragModifier

public XAxisDragModifier()

xAxisDragModifier = XAxisDragModifier()

Initializes a new instance of the XAxisDragModifier class.

ClipModeX

public ClipMode ClipModeX { get; set; }

value = xAxisDragModifier.ClipModeX
xAxisDragModifier.ClipModeX = value

Defines how panning behaves when you reach the edge of the X-Axis extents. e.g. ClipMode.ClipAtExtents prevents panning outside of the X-Axis, ClipMode.None allows panning outside

CalculateScaledRange

protected override IRange CalculateScaledRange(Point currentPoint, Point lastPoint, bool isSecondHalf, IAxis axis)

result = xAxisDragModifier.CalculateScaledRange(currentPoint, lastPoint, isSecondHalf, axis)

When overriden in a derived class, calculates an output IRange to apply to the associated AxisBaseAxis, given the input parameters

currentPoint

The current mouse position

lastPoint

The last mouse position

isSecondHalf

A flag, which determines how the scale operates, e.g. which half of the axis (top or bottom, left or right) was dragged

axis

The axis being operated on

Returns: The output IRange

GetCurrentAxis

protected override IAxis GetCurrentAxis()

result = xAxisDragModifier.GetCurrentAxis()

Gets the IAxis instance, which current modifier is associated with, on the parent UltrachartSurface
