# matplotlib.patches.ConnectionPatch

class `matplotlib.patches.``ConnectionPatch`(xyA, xyB, coordsA, coordsB=None, axesA=None, axesB=None, arrowstyle=’-‘, arrow_transmuter=None, connectionstyle=’arc3’, connector=None, patchA=None, patchB=None, shrinkA=0.0, shrinkB=0.0, mutation_scale=10.0, mutation_aspect=None, clip_on=False, dpi_cor=1.0, **kwargs)

  A `ConnectionPatch` class is to make connecting lines between two points (possibly in different axes).

  Connect point xyA in coordsA with point xyB in coordsB

  Valid keys are

  Key | Description
  --- | ---
  arrowstyle | the arrow style
  connectionstyle | the connection style
  relpos | default is (0.5, 0.5)
  patchA | default is bounding box of the text
  patchB | default is None
  shrinkA | default is 2 points
  shrinkB | default is 2 points
  mutation_scale | default is text size (in points)
  mutation_aspect | default is 1.
  ? | any key for `matplotlib.patches.PathPatch`

  coordsA and coordsB are strings that indicate the coordinates of xyA and xyB.

  Property | Description
  --- | ---
  ‘figure points’ | points from the lower left corner of the figure
  ‘figure pixels’ | pixels from the lower left corner of the figure
  ‘figure fraction’ | 0,0 is lower left of figure and 1,1 is upper, right
  ‘axes points’ | points from lower left corner of axes
  ‘axes pixels’ | pixels from lower left corner of axes
  ‘axes fraction’ | 0,1 is lower left of axes and 1,1 is upper right
  ‘data’ | use the coordinate system of the object being annotated (default)
  ‘offset points’ | Specify an offset (in points) from the xy value
  ‘polar’ | you can specify theta, r for the annotation, even in cartesian plots. Note that if you are using a polar axes, you do not need to specify polar for the coordinate system since that is the native “data” coordinate system.
