class pyqtgraph.Point.Point(*args)[source]#

Extension of QPointF which adds a few missing methods.

angle(a, units='degrees')[source]#

Returns the angle in degrees from the vector a to self.

Parameters
  • a (Point, QPointF or QPoint) – The Point to return the angle with

  • units (str, optional) – The units with which to compute the angle with, “degrees” or “radians”, default “degrees”

Returns

The angle between two vectors

Return type

float

cross(a)[source]#

Returns the cross product of a and this Point

dot(a)[source]#

Returns the dot product of a and this Point.

length()[source]#

Returns the vector length of this Point.

norm()[source]#

Returns a vector in the same direction with unit length.

proj(b)[source]#
