Properties

aspect (String)

The default is "equal".
Python methods:

Name	Parameters	Return Type
get_aspect()	-	String
set_aspect()	aspect : String	None

extent (List/Tuple)

Describes the bounding box the data is stretched to fill the image. The behaviour is similar to using the xMin, xMax, yMin, yMax properties on the Axis but this won't stretch the image to the desired coordinates. The List or Tuple typically looks like this:

extent: [x_min, x_max, y_min, y_max]

Note that you can only use tuples over the python interface and not in QML. The default is None.
Python methods:

Name	Parameters	Return Type
get_extent()	-	List/Tuple
set_extent()	extent : List/Tuple	None

x (Array/List)

summary.The default is [].
Python methods:

Name	Parameters	Return Type
get_x()	-	Array/List
set_x()	x : Array/List	None

interpolation (String)

The default is antialiased.
Python methods:

Name	Parameters	Return Type
get_interpolation()	-	String
set_interpolation()	interpolation : String	None

origin (String)

The default is lower.
Python methods:

Name	Parameters	Return Type
get_origin()	-	String
set_origin()	origin : String	None

resample (Bool)

The default is False.
Python methods:

Name	Parameters	Return Type
get_resample()	-	Bool
set_resample()	resample : Bool	None

filternorm (Bool)

The default is True.
Python methods:

Name	Parameters	Return Type
get_filternorm()	-	Bool
set_filternorm()	filternorm: Bool	None

filterrad (Float)

The default is 4.0.
Python methods:

Name	Parameters	Return Type
get_filternorm()	-	Float
set_filternorm()	filterrad : Float	None

visible (Bool)

Whether the object is drawn on the Axes or not The default is True.
Python methods:

Name	Parameters	Return Type
get_visible()	-	Bool
set_visible()	visible : Bool	None

alpha (Float)

The opacity/transparency value of the Artist, This must be a value between 0 and 1. The default is None.
Python methods:

Name	Parameters	Return Type
get_alpha()	-	Float

label(String)

The label displayed in the legend of the plot. The default is None.
Python methods:

Name	Parameters	Return Type
get_label()	-	String
set_label()	label : String	None

zOrder(Integer)

Position on the z-axis of the Artist in the drawing hierarchy. Higher means further in the front. The default is 0.
Python methods:

Name	Parameters	Return Type
get_zorder()	-	Integer
set_zorder()	label : Integer	None

cMap (String)

The colormap of the ScalarMappable. Can b one of the Matplotlib Colormaps. The default is viridis.
Python methods:

Name	Parameters	Return Type
