classmatplotlib.collections.PolyCollection(verts, sizes=None, closed=True, **kwargs)[source]
 
Bases: matplotlib.collections._CollectionWithSizes  Parameters 
 
vertslist of array-like


The sequence of polygons [verts0, verts1, ...] where each element verts_i defines the vertices of polygon i as a 2D array-like of shape (M, 2).  
sizesarray-like, default: None


Squared scaling factors for the polygons. The coordinates of each polygon verts_i are multiplied by the square-root of the corresponding entry in sizes (i.e., sizes specify the scaling of areas). The scaling is applied before the Artist master transform.  
closedbool, default: True


Whether the polygon should be closed by adding a CLOSEPOLY connection at the end.  **kwargs

Forwarded to Collection.       add_callback(func)[source]
 
Add a callback function that will be called whenever one of the Artist's properties changes.  Parameters 
 
funccallable


The callback function. It must have the signature: def func(artist: Artist) -> Any
 where artist is the calling Artist. Return values may exist but are ignored.    Returns 
 int

The observer id associated with the callback. This id can be used for removing the callback with remove_callback later.      See also  remove_callback
  
   autoscale()[source]
 
Autoscale the scalar limits on the norm instance using the current array 
   autoscale_None()[source]
 
Autoscale the scalar limits on the norm instance using the current array, changing only limits that are None 
   propertyaxes
 
The Axes instance the artist resides in, or None. 
   propertycallbacksSM[source]

   changed()[source]
 
Call this whenever the mappable is changed to notify all the callbackSM listeners to the 'changed' signal. 
   colorbar
 
The last colorbar associated with this ScalarMappable. May be None. 
   contains(mouseevent)[source]
 
Test whether the mouse event occurred in the collection. Returns bool, dict(ind=itemlist), where every item in itemlist contains the event. 
   convert_xunits(x)[source]
 
Convert x using the unit type of the xaxis. If the artist is not in contained in an Axes or if the xaxis does not have units, x itself is returned. 
   convert_yunits(y)[source]
 
Convert y using the unit type of the yaxis. If the artist is not in contained in an Axes or if the yaxis does not have units, y itself is returned. 
   draw(renderer)[source]
 
Draw the Artist (and its children) using the given renderer. This has no effect if the artist is not visible (Artist.get_visible returns False).  Parameters 
 
rendererRendererBase subclass.

   Notes This method is overridden in the Artist subclasses. 
   findobj(match=None, include_self=True)[source]
 
Find artist objects. Recursively find all Artist instances contained in the artist.  Parameters 
 match

A filter criterion for the matches. This can be  
None: Return all objects contained in artist. A function with signature def match(artist: Artist) -> bool. The result will only contain artists for which the function returns True. A class instance: e.g., Line2D. The result will only contain artists of this class or its subclasses (isinstance check).   
include_selfbool


Include self in the list to be checked for a match.    Returns 
 list of Artist

   
   format_cursor_data(data)[source]
 
Return a string representation of data.  Note This method is intended to be overridden by artist subclasses. As an end-user of Matplotlib you will most likely not call this method yourself.  The default implementation converts ints and floats and arrays of ints and floats into a comma-separated string enclosed in square brackets, unless the artist has an associated colorbar, in which case scalar values are formatted using the colorbar's formatter.  See also  get_cursor_data
  
   get_agg_filter()[source]
 
Return filter function to be used for agg filter. 
   get_alpha()[source]
 
Return the alpha value used for blending - not supported on all backends. 
   get_animated()[source]
 
Return whether the artist is animated. 
   get_array()[source]
 
Return the array of values, that are mapped to colors. The base class ScalarMappable does not make any assumptions on the dimensionality and shape of the array. 
   get_capstyle()[source]

   get_children()[source]
 
Return a list of the child Artists of this Artist. 
   get_clim()[source]
 
Return the values (min, max) that are mapped to the colormap limits. 
   get_clip_box()[source]

   get_clip_path()[source]
 
Return the clip path. 
   get_cmap()[source]
 
Return the Colormap instance. 
   get_cursor_data(event)[source]
 
Return the cursor data for a given event.  Note This method is intended to be overridden by artist subclasses. As an end-user of Matplotlib you will most likely not call this method yourself.  Cursor data can be used by Artists to provide additional context information for a given event. The default implementation just returns None. Subclasses can override the method and return arbitrary data. However, when doing so, they must ensure that format_cursor_data can convert the data to a string representation. The only current use case is displaying the z-value of an AxesImage in the status bar of a plot window, while moving the mouse.  Parameters 
 
eventmatplotlib.backend_bases.MouseEvent

Default is to return an empty bounding box at 0, 0. Be careful when using this function, the results will not update if the artist window extent of the artist changes. The extent can change due to any changes in the transform stack, such as changing the axes limits, the figure size, or the canvas used (as is done when saving a figure). This can lead to unexpected behavior where interactive figures will look fine on the screen, but will save incorrectly.

Return the artist's zorder. 
   have_units()[source]
 
Return whether units are set on any axis. 
   is_transform_set()[source]

Note: relim will not see collections even if the collection was added to the axes with autolim = True. Note: there is no support for removing the artist's legend entry. 
   remove_callback(oid)[source]
 
Remove a callback based on its observer id.  See also  add_callback

transformTransform, optional


Only used if path is a Path, in which case the given Path is converted to a TransformedPath using transform.     Notes For efficiency, if path is a Rectangle this method will set the clipping box to the corresponding rectangle and set the clipping path to None.

The sequence of polygons [verts0, verts1, ...] where each element verts_i defines the vertices of polygon i as a 2D array-like of shape (M, 2).  
closedbool, default: True


Whether the polygon should be closed by adding a CLOSEPOLY connection at the end.     
   set_picker(picker)[source]
 
Define the picking behavior of the artist.  Parameters 
 
pickerNone or bool or float or callable


This can be one of the following:  
None: Picking is disabled for this artist (default). A boolean: If True then picking will be enabled and the artist will fire a pick event if the mouse event is over the artist. A float: If picker is a number it is interpreted as an epsilon tolerance in points and the artist will fire off an event if its data is within epsilon of the mouse event. For some artists like lines and patch collections, the artist may provide additional data to the pick event that is generated, e.g., the indices of the data within epsilon of the pick event 
A function: If picker is callable, it is a user supplied function which determines whether the artist is hit by the mouse event: hit, props = picker(artist, mouseevent)
 to determine the hit test. if the mouse event is over the artist, return hit=True and props is a dictionary of properties you want added to the PickEvent attributes.       
   set_pickradius(pr)[source]
 
Set the pick radius used for containment tests.  Parameters 
 
prfloat


Pick radius, in points.     
   set_rasterized(rasterized)[source]
 
Force rasterized (bitmap) drawing for vector graphics output. Rasterized drawing is not supported by all artists. If you try to enable this on an artist that does not support it, the command has no effect and a warning will be issued. This setting is ignored for pixel-based output. See also Rasterization for vector graphics.  Parameters 
 
rasterizedbool

   
   set_sizes(sizes, dpi=72.0)[source]
 
Set the sizes of each member of the collection.  Parameters 
 
sizesndarray or None


The size to set for each element of the collection. The value is the 'area' of the element.  
dpifloat, default: 72


The dpi of the canvas.     
   set_sketch_params(scale=None, length=None, randomness=None)[source]
 
Set the sketch parameters.  Parameters 
 
scalefloat, optional


The amplitude of the wiggle perpendicular to the source line, in pixels. If scale is None, or not provided, no sketch filter will be provided.  
lengthfloat, optional


The length of the wiggle along the line, in pixels (default 128.0)  
randomnessfloat, optional


The scale factor by which the length is shrunken or expanded (default 16.0) The PGF backend uses this argument as an RNG seed and not as described above. Using the same seed yields the same random shape.     
   set_snap(snap)[source]
 
Set the snapping behavior. Snapping aligns positions with the pixel grid, which results in clearer images. For example, if a black line of 1px width was defined at a position in between two pixels, the resulting image would contain the interpolated value of that line in the pixel grid, which would be a grey value on both adjacent pixel positions. In contrast, snapping will move the line to the nearest integer pixel value, so that the resulting image will really contain a 1px wide black line. Snapping is currently only supported by the Agg and MacOSX backends.  Parameters 
 
snapbool or None


Possible values:  
True: Snap vertices to the nearest pixel center. 
False: Do not modify vertex positions. 
None: (auto) If the path contains only rectilinear line segments, round to the nearest pixel center.      
   set_transform(t)[source]
 
Set the artist transform.  Parameters 
 
tTransform

   
   set_url(url)[source]
 
Set the url for the artist.  Parameters 
 
urlstr

   
   set_urls(urls)[source]
 
 Parameters 
 
urlslist of str or None

   Notes URLs are currently only implemented by the SVG backend. They are ignored by all other backends. 
   set_verts(verts, closed=True)[source]
 
Set the vertices of the polygons.  Parameters 
 
vertslist of array-like


The sequence of polygons [verts0, verts1, ...] where each element verts_i defines the vertices of polygon i as a 2D array-like of shape (M, 2).  
closedbool, default: True


Whether the polygon should be closed by adding a CLOSEPOLY connection at the end.     
   set_verts_and_codes(verts, codes)[source]
 
Initialize vertices with path codes. 
   set_visible(b)[source]
 
Set the artist's visibility.  Parameters 
 
bbool

   
   set_zorder(level)[source]
 
Set the zorder for the artist. Artists with lower zorder values are drawn first.  Parameters 
 
levelfloat

   
   propertystale
 
Whether the artist is 'stale' and needs to be re-drawn for the output to match the internal state of the artist. 
   propertysticky_edges
 
x and y sticky edge lists for autoscaling. When performing autoscaling, if a data limit coincides with a value in the corresponding sticky_edges list, then no margin will be added--the view limit "sticks" to the edge. A typical use case is histograms, where one usually expects no margin on the bottom edge (0) of the histogram. Moreover, margin expansion "bumps" against sticky edges and cannot cross them. For example, if the upper data limit is 1.0, the upper view limit computed by simple margin application is 1.2, but there is a sticky edge at 1.1, then the actual upper view limit will be 1.1. This attribute cannot be assigned to; however, the x and y lists can be modified in place as needed. Examples >>> artist.sticky_edges.x[:] = (xmin, xmax)
>>> artist.sticky_edges.y[:] = (ymin, ymax)
 
   to_rgba(x, alpha=None, bytes=False, norm=True)[source]
 
Return a normalized rgba array corresponding to x. In the normal case, x is a 1D or 2D sequence of scalars, and the corresponding ndarray of rgba values will be returned, based on the norm and colormap set for this ScalarMappable. There is one special case, for handling images that are already rgb or rgba, such as might have been read from an image file. If x is an ndarray with 3 dimensions, and the last dimension is either 3 or 4, then it will be treated as an rgb or rgba array, and no mapping will be done. The array can be uint8, or it can be floating point with values in the 0-1 range; otherwise a ValueError will be raised. If it is a masked array, the mask will be ignored. If the last dimension is 3, the alpha kwarg (defaulting to 1) will be used to fill in the transparency. If the last dimension is 4, the alpha kwarg is ignored; it does not replace the pre-existing alpha. A ValueError will be raised if the third dimension is other than 3 or 4. In either case, if bytes is False (default), the rgba array will be floats in the 0-1 range; if it is True, the returned rgba array will be uint8 in the 0 to 255 range. If norm is False, no normalization of the input data is performed, and it is assumed to be in the range (0-1).
