PlotAxes.parametric¶
- PlotAxes.parametric(x, y, c, *, interp=0, scalex=True, scaley=True, **kwargs)[source]¶
Plot a parametric line.
- Parameters
*args (
y
orx
,y
) – The data passed as positional or keyword arguments. Interpreted as follows:If only
y
coordinates are passed, try to infer thex
coordinates from theSeries
orDataFrame
indices or theDataArray
coordinates. Otherwise, thex
coordinates arenp.arange(0, y.shape[0])
.If the
y
coordinates are a 2D array, plot each column of data in succession (except where each column of data represents a statistical distribution, as withboxplot
,violinplot
, or when usingmeans=True
ormedians=True
).If any arguments are
pint.Quantity
, auto-add the pint unit registry to matplotlib’s unit registry usingsetup_matplotlib
. Apint.Quantity
embedded in anxarray.DataArray
is also supported.
c, color, colors, values (array-like, optional) – The parametric coordinate. These can be passed as a third positional argument or as a keyword argument. They can also be string labels instead of numbers and the resulting colorbar ticks will be labeled accordingly.
interp (
int
, optional) – Interpolate to this many additional points between the parametric coordinates. Default is0
. This can be increased to make the color gradations between a small number of coordinates appear “smooth”.data (dict-like, optional) – A dict-like dataset container (e.g.,
DataFrame
orDataArray
). If passed, positional arguments can optionally be stringdata
keys and the arrays used for plotting are retrieved withdata[key]
. This is a native matplotlib feature.autoformat (
bool
, optional) – Whether thex
axis labels,y
axis labels, axis formatters, axes titles, legend titles, and colorbar labels are automatically configured when aSeries
,DataFrame
,DataArray
, orQuantity
is passed to the plotting command. Default isrc.autoformat
=True
.
- Other Parameters
cmap (
colormap-spec
, optional) – The colormap specifer, passed to theColormap
constructor function.c, color, colors (
color-spec
or sequence ofcolor-spec
, optional) – The color(s) used to create aDiscreteColormap
. If not passed,cmap
is used.norm (
norm-spec
, optional) – The continuous colormap normalizer, passed to theNorm
constructor function. Ifdiscrete
isTrue
this is also used to normalize values passed toDiscreteNorm
before colors is selected.discrete (
bool
, optional) – IfFalse
, thenDiscreteNorm
is not applied to the colormap. Instead, for non-contour plots, the number of levels will be roughly controlled byrc['cmap.lut']
. This has a similar effect to usinglevels=large_number
but it may improve rendering speed. Default isFalse
forimshow
,matshow
,spy
,hexbin
,hist2d
, andheatmap
plots, butTrue
otherwise.sequential, diverging, cyclic, qualitative (
bool
, optional) – Boolean arguments used ifcmap
is not passed. Set these toTrue
to use the defaultrc['cmap.sequential']
,rc['cmap.diverging']
,rc['cmap.cyclic']
, andrc['cmap.qualitative']
colormaps. Thediverging
option also appliesDivergingNorm
as the default continuous normalizer.extend (
{{'neither', 'min', 'max', 'both'}}
, optional) – Whether to assign unique colors to out-of-bounds data and draw colorbar “extensions” when a colorbar is drawn.vmin, vmax (
float
, optional) – Used to determine level locations iflevels
orvalues
is an integer. Actual levels may not fall exactly onvmin
andvmax
, but the minimum level will be no smaller thanvmin
and the maximum level will be no larger thanvmax
. Ifvmin
orvmax
are not provided, the minimum and maximum data values are used.inbounds (
bool
, optional) – Whether to restrict the defaulty
(x
) axis limits to account for only in-bounds data when thex
(y
) axis limits have been locked. Default isrc['axes.inbounds']
=True
. See alsorc['cmap.inbounds']
.scalex, scaley (
bool
, optional) – Whether the view limits are adapted to the data limits. The values are passed on toautoscale_view
.colorbar (
bool
,int
, orstr
, optional) – If notNone
, this is a location specifying where to draw an inner or outer colorbar from the resulting object(s). IfTrue
, the defaultrc['colorbar.loc']
='right'
is used. If the same location is used in successive plotting calls, object(s) will be added to the existing colorbar in that location (valid for colorbars built from lists of artists). Valid locations are shown in incolorbar
.colorbar_kw (dict-like, optional) – Extra keyword args for the call to
colorbar
.legend (
bool
,int
, orstr
, optional) – Location specifying where to draw an inner or outer legend from the resulting object(s). IfTrue
, the defaultrc['legend.loc']
='best'
is used. If the same location is used in successive plotting calls, object(s) will be added to existing legend in that location. Valid locations are shown inlegend
.legend_kw (dict-like, optional) – Extra keyword args for the call to
legend
.**kwargs – Valid
LineCollection
properties.
- Returns
LineCollection
– The parametric line. See this matplotlib example.
