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

Возвращает: The output IRange

GetCurrentAxis() : IAxis

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

OnModifierMouseDown(ModifierMouseArgs)

Called when a Mouse Button is pressed on the parent UltrachartSurface

e: Arguments detailing the mouse button operation

OnModifierMouseUp(ModifierMouseArgs)
