class matplotlib.projections.geo.AitoffAxes(*args, **kwargs)

Bases: GeoAxes

Build an Axes in a figure.

Parameters:

figFigure

The Axes is built in the Figure fig.

*args

*args can be a single (left, bottom, width, height) rectangle or a single Bbox. This specifies the rectangle (in figure coordinates) where the Axes is positioned.

*args can also consist of three numbers or a single three-digit number; in the latter case, the digits are considered as independent numbers. The numbers are interpreted as (nrows, ncols, index): (nrows, ncols) specifies the size of an array of subplots, and index is the 1-based index of the subplot being created. Finally, *args can also directly be a SubplotSpec instance.

sharex, shareyAxes, optional

The x- or y-axis is shared with the x- or y-axis in the input Axes.

frameonbool, default: True

Whether the Axes frame is visible.

box_aspectfloat, optional

Set a fixed aspect for the Axes box, i.e. the ratio of height to width. See set_box_aspect for details.

class AitoffTransform(resolution)

Bases: _GeoTransform

The base Aitoff transform.

Create a new geographical transform.

Resolution is the number of steps to interpolate between each input line segment to approximate its path in curved space.

has_inverse = True

True if this transform has a corresponding inverse transform.

inverted()

Return the corresponding inverse transformation.

It holds x == self.inverted().transform(self.transform(x)).

transform(values) is always equivalent to transform_affine(transform_non_affine(values)).

In non-affine transformations, this is generally equivalent to transform(values). In affine transformations, this is always a no-op.

Parameters:

valuesarray

The input values as NumPy array of length input_dims or shape (N x input_dims).

Returns:

array

The output values as NumPy array of length output_dims or shape (N x output_dims), depending on the input.

transform(values) is always equivalent to transform_affine(transform_non_affine(values)).

In non-affine transformations, this is generally equivalent to transform(values). In affine transformations, this is always a no-op.

Returns:

Axes

The new Axes object.

class InvertedLambertTransform(center_longitude, center_latitude, resolution)

Bases: _GeoTransform

Create a new geographical transform.

Resolution is the number of steps to interpolate between each input line segment to approximate its path in curved space.

has_inverse = True

True if this transform has a corresponding inverse transform.

inverted()

Return the corresponding inverse transformation.

It holds x == self.inverted().transform(self.transform(x)).

The return value of this method should be treated as temporary. An update to self does not cause a corresponding update to its inverted copy.

transform_non_affine(xy)

Apply only the non-affine part of this transformation.

transform(values) is always equivalent to transform_affine(transform_non_affine(values)).

In non-affine transformations, this is generally equivalent to transform(values). In affine transformations, this is always a no-op.

Parameters:

valuesarray

The input values as NumPy array of length input_dims or shape (N x input_dims).

Returns:

array

The output values as NumPy array of length output_dims or shape (N x output_dims), depending on the input.

class LambertTransform(center_longitude, center_latitude, resolution)

Bases: _GeoTransform

The base Lambert transform.

Create a new Lambert transform. Resolution is the number of steps to interpolate between each input line segment to approximate its path in curved Lambert space.

has_inverse = True

True if this transform has a corresponding inverse transform.

inverted()

Return the corresponding inverse transformation.

It holds x == self.inverted().transform(self.transform(x)).

The return value of this method should be treated as temporary. An update to self does not cause a corresponding update to its inverted copy.

transform_non_affine(ll)

Apply only the non-affine part of this transformation.

transform(values) is always equivalent to transform_affine(transform_non_affine(values)).

In non-affine transformations, this is generally equivalent to transform(values). In affine transformations, this is always a no-op.

Parameters:

valuesarray

The input values as NumPy array of length input_dims or shape (N x input_dims).

Returns:

array

The output values as NumPy array of length output_dims or shape (N x output_dims), depending on the input.

clear()

Clear the Axes.

class matplotlib.projections.geo.MollweideAxes(*args, **kwargs)

Bases: GeoAxes

Build an Axes in a figure.

Parameters:

figFigure

The Axes is built in the Figure fig.

*args

*args can be a single (left, bottom, width, height) rectangle or a single Bbox. This specifies the rectangle (in figure coordinates) where the Axes is positioned.

*args can also consist of three numbers or a single three-digit number; in the latter case, the digits are considered as independent numbers. The numbers are interpreted as (nrows, ncols, index): (nrows, ncols) specifies the size of an array of subplots, and index is the 1-based index of the subplot being created. Finally, *args can also directly be a SubplotSpec instance.

sharex, shareyAxes, optional

The x- or y-axis is shared with the x- or y-axis in the input Axes.

frameonbool, default: True

Whether the Axes frame is visible.

box_aspectfloat, optional

Set a fixed aspect for the Axes box, i.e. the ratio of height to width. See set_box_aspect for details.

**kwargs

Other optional keyword arguments:
