GraphicsWidgetAnchor

class pyqtgraph.GraphicsWidgetAnchor

Class used to allow GraphicsWidgets to anchor to a specific position on their parent.

__init__()
anchor(itemPos, parentPos, offset=(0, 0))

Anchors the item at its local itemPos to the item’s parent at parentPos. Both positions are expressed in values relative to the size of the item or parent; a value of 0 indicates left or top edge, while 1 indicates right or bottom edge.

Optionally, offset may be specified to introduce an absolute offset.

Example: anchor a box such that its upper-right corner is fixed 10px left and 10px down from its parent’s upper-right corner:

box.anchor(itemPos=(1,0), parentPos=(1,0), offset=(-10,10))
