Mô tả
The docstring of choropleth_map states that locations are to be "interpreted according to locationmode" (as with other mapping functions), but this parameter seems to be missing from the signature of this function.
I'm using plotly v5.24.1
import plotly.express as px
px.choropleth_map?
Signature:
px.choropleth_map(
data_frame=None,
geojson=None,
featureidkey=None,
locations=None,
color=None,
hover_name=None,
hover_data=None,
custom_data=None,
animation_frame=None,
animation_group=None,
category_orders=None,
labels=None,
color_discrete_sequence=None,
color_discrete_map=None,
color_continuous_scale=None,
range_color=None,
color_continuous_midpoint=None,
opacity=None,
zoom=8,
center=None,
map_style=None,
title=None,
template=None,
width=None,
height=None,
) -> plotly.graph_objs._figure.Figure
Docstring:
In a choropleth map, each row of `data_frame` is represented by a
colored region on the map.
Parameters
----------
data_frame: DataFrame or array-like or dict
This argument needs to be passed for column names (and not keyword
names) to be used. Array-like and dict are transformed internally to a
pandas DataFrame. Optional: if missing, a DataFrame gets constructed
under the hood using the other arguments.
geojson: GeoJSON-formatted dict
Must contain a Polygon feature collection, with IDs, which are
references from `locations`.
featureidkey: str (default: `'id'`)
Path to field in GeoJSON feature object with which to match the values
passed in to `locations`.The most common alternative to the default is
of the form `'properties.<key>`.
locations: str or int or Series or array-like
Either a name of a column in `data_frame`, or a pandas Series or
array_like object. Values from this column or array_like are to be
interpreted according to `locationmode` and mapped to
longitude/latitude.
color: str or int or Series or array-like
Either a name of a column in `data_frame`, or a pandas Series or
array_like object. Values from this column or array_like are used to
assign color to marks.
hover_name: str or int or Series or array-like
Either a name of a column in `data_frame`, or a pandas Series or
array_like object. Values from this column or array_like appear in bold
in the hover tooltip.
hover_data: str, or list of str or int, or Series or array-like, or dict
Either a name or list of names of columns in `data_frame`, or pandas
Series, or array_like objects or a dict with column names as keys, with
values True (for default formatting) False (in order to remove this
column from hover information), or a formatting string, for example
':.3f' or '|%a' or list-like data to appear in the hover tooltip or
tuples with a bool or formatting string as first element, and list-like
data to appear in hover as second element Values from these columns
appear as extra data in the hover tooltip.
custom_data: str, or list of str or int, or Series or array-like
Either name or list of names of columns in `data_frame`, or pandas
Series, or array_like objects Values from these columns are extra data,
to be used in widgets or Dash callbacks for example. This data is not
user-visible but is included in events emitted by the figure (lasso
selection etc.)
animation_frame: str or int or Series or array-like
Either a name of a column in `data_frame`, or a pandas Series or
array_like object. Values from this column or array_like are used to
assign marks to animation frames.
animation_group: str or int or Series or array-like
Either a name of a column in `data_frame`, or a pandas Series or
array_like object. Values from this column or array_like are used to
provide object-constancy across animation frames: rows with matching
`animation_group`s will be treated as if they describe the same object
in each frame.
category_orders: dict with str keys and list of str values (default `{}`)
By default, in Python 3.6+, the order of categorical values in axes,
legends and facets depends on the order in which these values are first
encountered in `data_frame` (and no order is guaranteed by default in
Python below 3.6). This parameter is used to force a specific ordering
of values per column. The keys of this dict should correspond to column
names, and the values should be lists of strings corresponding to the
specific display order desired.
labels: dict with str keys and str values (default `{}`)
By default, column names are used in the figure for axis titles, legend
entries and hovers. This parameter allows this to be overridden. The
keys of this dict should correspond to column names, and the values
should correspond to the desired label to be displayed.
color_discrete_sequence: list of str
Strings should define valid CSS-colors. When `color` is set and the
values in the corresponding column are not numeric, values in that
column are assigned colors by cycling through `color_discrete_sequence`
in the order described in `category_orders`, unless the value of
`color` is a key in `color_discrete_map`. Various useful color
sequences are available in the `plotly.express.colors` submodules,
specifically `plotly.express.colors.qualitative`.
color_discrete_map: dict with str keys and str values (default `{}`)
String values should define valid CSS-colors Used to override
`color_discrete_sequence` to assign a specific colors to marks
corresponding with specific values. Keys in `color_discrete_map` should
be values in the column denoted by `color`. Alternatively, if the
values of `color` are valid colors, the string `'identity'` may be
passed to cause them to be used directly.
color_continuous_scale: list of str
Strings should define valid CSS-colors This list is used to build a
continuous color scale when the column denoted by `color` contains
numeric data. Various useful color scales are available in the
`plotly.express.colors` submodules, specifically
`plotly.express.colors.sequential`, `plotly.express.colors.diverging`
and `plotly.express.colors.cyclical`.
range_color: list of two numbers
If provided, overrides auto-scaling on the continuous color scale.
color_continuous_midpoint: number (default `None`)
If set, computes the bounds of the continuous color scale to have the
desired midpoint. Setting this value is recommended when using
`plotly.express.colors.diverging` color scales as the inputs to
`color_continuous_scale`.
opacity: float
Value between 0 and 1. Sets the opacity for markers.
zoom: int (default `8`)
Between 0 and 20. Sets map zoom level.
center: dict
Dict keys are `'lat'` and `'lon'` Sets the center point of the map.
map_style: str (default `'basic'`)
Identifier of base map style. Allowed values are `'basic'`, `'carto-
darkmatter'`, `'carto-darkmatter-nolabels'`, `'carto-positron'`,
`'carto-positron-nolabels'`, `'carto-voyager'`, `'carto-voyager-
nolabels'`, `'dark'`, `'light'`, `'open-street-map'`, `'outdoors'`,
`'satellite'`, `'satellite-streets'`, `'streets'`, `'white-bg'`.
title: str
The figure title.
template: str or dict or plotly.graph_objects.layout.Template instance
The figure template name (must be a key in plotly.io.templates) or
definition.
width: int (default `None`)
The figure width in pixels.
height: int (default `None`)
The figure height in pixels.

Hướng nghiên cứu
Bắt đầu trong plotly/express/_chart_types.py, nơi issue xác định hàm choropleth_map và signature của hàm. So sánh các tham số liên quan đến vị trí và tài liệu của hàm này với các hàm ánh xạ khác được đề cập trong issue, sau đó xác minh rằng hàm chấp nhận locationmode và signature cùng docstring của hàm là nhất quán.
