GeoAxes.format¶
- GeoAxes.format()[source]¶
Modify map limits, longitude and latitude gridlines, geographic features, and more.
- Parameters
lonlim, latlim (
2-tuple
offloat
, optional) – For cartopy axes only. The approximate longitude and latitude boundaries of the map, applied withset_extent
. Basemap axes extents must be declared by passing keyword arguments toProj
.boundinglat (
float
, optional) – For cartopy axes only. The edge latitude for the circle bounding North Pole and South Pole-centered projections. Basemap bounding latitudes must be declared by passing keyword arguments toProj
.longrid, latgrid (
bool
, optional) – Whether to draw longitude and latitude gridlines. Default isrc.grid
=True
. Usegrid
to toggle both.longridminor, latgridminor (
bool
, optional) – Whether to draw “minor” longitude and latitude lines. Default isrc.gridminor
=False
. Usegridminor
to toggle both.lonlines, latlines (optional) – Aliases for
lonlocator
,latlocator
.lonlocator, latlocator (
locator-spec
, optional) – Used to determine the longitude and latitude gridline locations. Passed to theLocator
constructor. Can be string, float, list of float, ormatplotlib.ticker.Locator
instance.For basemap or cartopy < 0.18, the defaults are
'deglon'
and'deglat'
, which correspond to theLongitudeLocator
andLatitudeLocator
locators (adapted from cartopy). For cartopy >= 0.18, the defaults are'dmslon'
and'dmslat'
, which uses the same locators withdms=True
. This selects gridlines at nice degree-minute-second intervals when the map extent is very small.lonlines_kw, latlines_kw (optional) – Aliases for
lonlocator_kw
,latlocator_kw
.lonlocator_kw, latlocator_kw (dict-like, optional) – Keyword arguments passed to the
matplotlib.ticker.Locator
class.lonminorlocator, latminorlocator, lonminorlines, latminorlines (optional) – As with
lonlocator
andlatlocator
but for the “minor” gridlines. The defaults arerc['grid.lonminorstep']
andrc['grid.latminorstep']
.lonminorlines_kw, latminorlines_kw (optional) – Aliases for
lonminorlocator_kw
,latminorlocator_kw
.lonminorlocator_kw, latminorlocator_kw (optional) – As with
lonlocator_kw
andlatlocator_kw
but for the “minor” gridlines.latmax (
float
, optional) – The maximum absolute latitude for longitude and latitude gridlines. Longitude gridlines are cut off poleward of this latitude for all basemap projections and cartopy projections predating cartopy 0.18. Default is80
.labels (
bool
, optional) – Setslonlabels
andlatlabels
toTrue
. Default isrc['grid.labels']
=False
.lonlabels, latlabels (optional) – Whether to label longitudes and latitudes, and on which sides of the map. There are four different options:
Boolean
True
. Indicates the left side for latitudes, bottom side for longitudes.A string or tuple of strings indicating the side names, e.g.
'left'
for latitudes or'bottom'
for longitudes.A string indicating the side names with single characters, e.g.
'lr'
for latitudes or'bt'
for longitudes.A boolean 2-tuple indicating whether to draw labels on the
(left, right)
sides for latitudes, or(bottom, top)
sides for longitudes.A boolean 4-tuple indicating whether to draw labels on the
(left, right, bottom, top)
sides, as with the basemapdrawmeridians
anddrawparallels
labels
keyword.
lonformatter, latformatter (
formatter-spec
, optional) – Formatter used to style longitude and latitude gridline labels. Passed to theFormatter
constructor. Can be string, list of string, ormatplotlib.ticker.Formatter
instance.For basemap or cartopy < 0.18, the defaults are
'deglon'
and'deglat'
, which correspond toSimpleFormatter
presets with degree symbols and cardinal direction suffixes. For cartopy >= 0.18, the defaults are'dmslon'
and'dmslat'
, which uses cartopy’sLongitudeFormatter
andLatitudeFormatter
formatters withdms=True
. This formats gridlines that do not fall on whole degrees as “minutes” and “seconds” rather than decimal degrees.lonformatter_kw, latformatter_kw (dict-like, optional) – Keyword arguments passed to the
matplotlib.ticker.Formatter
class.loninline, latinline, inlinelabels (
bool
, optional) – For cartopy axes only. Whether to draw inline longitude and latitude gridline labels. Default isrc['grid.inlinelabels']
=False
.rotatelabels (
bool
, optional) – For cartopy axes only. Whether to rotate longitude and latitude gridline labels. Default isrc['grid.rotatelabels']
=False
.labelpad (
unit-spec
, optional) – For cartopy axes only. The padding between the map boundary and longitude and latitude gridline labels. Default isrc['grid.labelpad']
=4.0
. If float, units are points. If string, interpreted byunits
.dms (
bool
, optional) – For cartopy axes only. Specifies whether the default locators and formatters should use “minutes” and “seconds” for gridline labels on small scales rather than decimal degrees. Setting this toFalse
is equivalent to specifyingax.format(lonlocator='deglon', latlocator='deglon')
andax.format(lonformatter='deglon', latformatter='deglat')
. Default isrc['grid.dmslabels']
=True

, optional) – Toggles various geographic features. These are actually therc.land
,rc.ocean
,rc.coast
,rc.rivers
,rc.lakes
,rc.borders
, andrc.innerborders
settings passed tocontext
. The style can be modified using additionalrc
settings.For example, to change
rc['land.color']
, useax.format(landcolor='green')
, and to changerc['land.zorder']
, useax.format(landzorder=4)
.reso (
{'lo', 'med', 'hi', 'x-hi', 'xx-hi'}
, optional) – For cartopy axes only. The resolution of geographic features. For basemap axes, this must be passed toProj

).gridlabelcolor (
color-spec
, optional) – Color for the grid labels. Inherits fromcolor
by default.

.suptitle_kw (optional) – Additional settings used to update the super title with

.mathtext_fallback (
bool
orstr
, optional) – Apply thisrc['mathtext.fallback']
value when drawing the figure. IfTrue
or string, unavailable glyphs are replaced with a glyph from a fallback font (Computer Modern by default). Otherwise, they are replaced with the “¤” dummy character. For details see this mathtext tutorial.rc_mode (
int
, optional) – The context mode passed tocontext
.rc_kw (dict-like, optional) – An alternative to passing extra keyword arguments. See below.
**kwargs – Passed to
proplot.config.Configurator.context
and used to update the axes-relevantrc
settings. For example,abc='A.'
modifies therc.abc
setting,titleloc='left'
modifies therc['title.loc']
setting,gridminor=True
modifies therc.gridminor
setting, andgridbelow=True
modifies therc['grid.below']
setting. Many of the keyword arguments documented above are actually applied by updating therc
settings then retrieving the updated settings.
