Personnalisation de Matplotlib avec des feuilles de style et rcParams #

Conseils pour personnaliser les propriétés et les styles par défaut de Matplotlib.

Il existe trois façons de personnaliser Matplotlib :

Définition de rcParams lors de l'exécution .

Utilisation des feuilles de style .

Modification de votre fichier matplotlibrc .

La définition de rcParams au moment de l'exécution a priorité sur les feuilles de style, les feuilles de style ont priorité sur les matplotlibrcfichiers.

Paramètres rc d'exécution #

Vous pouvez modifier dynamiquement les paramètres rc (configuration d'exécution) par défaut dans un script python ou de manière interactive à partir du shell python. Tous les paramètres rc sont stockés dans une variable de type dictionnaire appelée matplotlib.rcParams, qui est globale au package matplotlib. Voir matplotlib.rcParamspour une liste complète des rcParams configurables. rcParams peut être modifié directement, par exemple :

import numpy as np
import matplotlib.pyplot as plt
import matplotlib as mpl
from cycler import cycler
mpl.rcParams['lines.linewidth'] = 2
mpl.rcParams['lines.linestyle'] = '--'
data = np.random.randn(50)
plt.plot(data)

[<matplotlib.lines.Line2D object at 0x7f2cdd6a05b0>]

Notez que pour changer la plotcouleur habituelle, vous devez modifier la propriété prop_cycle des axes :

mpl.rcParams['axes.prop_cycle'] = cycler(color=['r', 'g', 'b', 'y'])
plt.plot(data)  # first color is red

[<matplotlib.lines.Line2D object at 0x7f2cdda41e70>]

Matplotlib fournit également quelques fonctions pratiques pour modifier les paramètres rc. matplotlib.rcpeut être utilisé pour modifier plusieurs paramètres dans un seul groupe à la fois, en utilisant des arguments de mots-clés :

mpl.rc('lines', linewidth=4, linestyle='-.')
plt.plot(data)

[<matplotlib.lines.Line2D object at 0x7f2cdd6a0b50>]

Paramètres rc temporaires #

L' matplotlib.rcParamsobjet peut également être modifié temporairement à l'aide du matplotlib.rc_contextgestionnaire de contexte :

with mpl.rc_context({'lines.linewidth': 2, 'lines.linestyle': ':'}):
    plt.plot(data)

matplotlib.rc_contextpeut également être utilisé comme décorateur pour modifier les valeurs par défaut d'une fonction :

@mpl.rc_context({'lines.linewidth': 3, 'lines.linestyle': '-'})
def plotting_function():
    plt.plot(data)

plotting_function()

matplotlib.rcdefaultsrestaurera les paramètres par défaut standard de Matplotlib.

Il existe un certain degré de validation lors de la définition des valeurs de rcParams, voir matplotlib.rcsetuppour plus de détails.

Utilisation des feuilles de style #

Une autre façon de modifier l'apparence visuelle des tracés consiste à définir les rcParams dans une soi-disant feuille de style et à importer cette feuille de style avec matplotlib.style.use. De cette façon, vous pouvez basculer facilement entre différents styles en changeant simplement la feuille de style importée. Une feuille de style ressemble à un fichier matplotlibrc , mais dans une feuille de style, vous ne pouvez définir que des rcParams liés au style réel d'un tracé. Les autres rcParams, comme backend , seront ignorés. matplotlibrcles fichiers prennent en charge tous les rcParams. La logique derrière cela est de rendre les feuilles de style portables entre différentes machines sans avoir à se soucier des dépendances qui pourraient ou non être installées sur une autre machine. Pour une liste complète des rcParams, voir matplotlib.rcParams. Pour une liste des rcParams qui sont ignorés dans les feuilles de style, voirmatplotlib.style.use.

Il existe un certain nombre de styles prédéfinis fournis par Matplotlib . Par exemple, il existe un style prédéfini appelé "ggplot", qui émule l'esthétique de ggplot (un package de traçage populaire pour R ). Pour utiliser ce style, ajoutez :

plt.style.use('ggplot')

Pour répertorier tous les styles disponibles, utilisez :

print(plt.style.available)

['Solarize_Light2', '_classic_test_patch', '_mpl-gallery', '_mpl-gallery-nogrid', 'bmh', 'classic', 'dark_background', 'fast', 'fivethirtyeight', 'ggplot', 'grayscale', 'seaborn-v0_8', 'seaborn-v0_8-bright', 'seaborn-v0_8-colorblind', 'seaborn-v0_8-dark', 'seaborn-v0_8-dark-palette', 'seaborn-v0_8-darkgrid', 'seaborn-v0_8-deep', 'seaborn-v0_8-muted', 'seaborn-v0_8-notebook', 'seaborn-v0_8-paper', 'seaborn-v0_8-pastel', 'seaborn-v0_8-poster', 'seaborn-v0_8-talk', 'seaborn-v0_8-ticks', 'seaborn-v0_8-white', 'seaborn-v0_8-whitegrid', 'tableau-colorblind10']

Définir son propre style #

Vous pouvez créer des styles personnalisés et les utiliser en appelant style.useavec le chemin ou l'URL de la feuille de style.

Par exemple, vous souhaiterez peut-être créer ./images/presentation.mplstyleavec les éléments suivants :

axes.titlesize : 24
axes.labelsize : 20
lines.linewidth : 3
lines.markersize : 10
xtick.labelsize : 16
ytick.labelsize : 16

Ensuite, lorsque vous souhaitez adapter un tracé conçu pour un papier à un tracé qui s'intègre bien dans une présentation, vous pouvez simplement ajouter :

>>> import matplotlib.pyplot as plt
>>> plt.style.use('./images/presentation.mplstyle')

Alternativement, vous pouvez faire connaître votre style à Matplotlib en plaçant votre <style-name>.mplstylefichier dans mpl_configdir/stylelib. Vous pouvez ensuite charger votre feuille de style personnalisée avec un appel à style.use(<style-name>). Par défaut mpl_configdirdevrait être ~/.config/matplotlib, mais vous pouvez vérifier où se trouve le vôtre avec matplotlib.get_configdir(); vous devrez peut-être créer ce répertoire. Vous pouvez également modifier le répertoire dans lequel Matplotlib recherche le dossier stylelib/ en définissant leMPLCONFIGDIRvariable d'environnement, consultez la configuration de matplotlib et les emplacements des répertoires de cache .

Notez qu'une feuille de style personnalisée dans mpl_configdir/stylelibremplacera une feuille de style définie par Matplotlib si les styles ont le même nom.

Une fois votre <style-name>.mplstylefichier dans l'approprié mpl_configdirvous pouvez préciser votre style avec :

>>> import matplotlib.pyplot as plt
>>> plt.style.use(<style-name>)

Styles de composition #

Les feuilles de style sont conçues pour être composées ensemble. Ainsi, vous pouvez avoir une feuille de style qui personnalise les couleurs et une feuille de style distincte qui modifie la taille des éléments pour les présentations. Ces styles peuvent facilement être combinés en passant une liste de styles :

>>> import matplotlib.pyplot as plt
>>> plt.style.use(['dark_background', 'presentation'])

Notez que les styles plus à droite écraseront les valeurs déjà définies par les styles à gauche.

Coiffage temporaire #

Si vous souhaitez uniquement utiliser un style pour un bloc de code spécifique mais que vous ne souhaitez pas modifier le style global, le package de style fournit un gestionnaire de contexte pour limiter vos modifications à une portée spécifique. Pour isoler vos changements de style, vous pouvez écrire quelque chose comme ceci :

with plt.style.context('dark_background'):
    plt.plot(np.sin(np.linspace(0, 2 * np.pi)), 'r-o')
plt.show()

Le `matplotlibrc`dossier #

Matplotlib utilise matplotlibrcdes fichiers de configuration pour personnaliser toutes sortes de propriétés, que nous appelons 'rc settings' ou 'rc parameters'. Vous pouvez contrôler les valeurs par défaut de presque toutes les propriétés dans Matplotlib : taille de la figure et DPI, largeur de ligne, couleur et style, axes, propriétés d'axe et de grille, propriétés de texte et de police, etc. Le matplotlibrcest lu au démarrage pour configurer Matplotlib. Matplotlib recherche matplotlibrcdans quatre emplacements, dans l'ordre suivant :

matplotlibrcdans le répertoire de travail courant, généralement utilisé pour des personnalisations spécifiques que vous ne souhaitez pas appliquer ailleurs.
$MATPLOTLIBRCsi c'est un fichier, sinon $MATPLOTLIBRC/matplotlibrc.
Il regarde ensuite dans un endroit spécifique à l'utilisateur, en fonction de votre plate-forme :
- Sous Linux et FreeBSD, il regarde dans .config/matplotlib/matplotlibrc(ou $XDG_CONFIG_HOME/matplotlib/matplotlibrc) si vous avez personnalisé votre environnement.
- Sur d'autres plates-formes, il regarde dans .matplotlib/matplotlibrc.
Voir la configuration de matplotlib et les emplacements des répertoires de cache .
INSTALL/matplotlib/mpl-data/matplotlibrc, où INSTALLest quelque chose comme /usr/lib/python3.9/site-packagessur Linux, et peut-être C:\Python39\Lib\site-packagessur Windows. Chaque fois que vous installez matplotlib, ce fichier sera écrasé, donc si vous voulez que vos personnalisations soient enregistrées, veuillez déplacer ce fichier dans votre répertoire matplotlib spécifique à l'utilisateur.

Une fois qu'un matplotlibrcfichier a été trouvé, il ne recherchera aucun des autres chemins. Lorsqu'une feuille de style est donnée avec style.use('<path>/<style-name>.mplstyle'), les paramètres spécifiés dans la feuille de style ont priorité sur les paramètres du matplotlibrcfichier.

Pour afficher d'où le fichier actuellement actif matplotlibrca été chargé, on peut faire ce qui suit :

>>> import matplotlib
>>> matplotlib.matplotlib_fname()
'/home/foo/.config/matplotlib/matplotlibrc'

Voir ci-dessous pour un exemple de fichier matplotlibrc et voir matplotlib.rcParamspour une liste complète des rcParams configurables.

`matplotlibrc`Le fichier par défaut #

#### MATPLOTLIBRC FORMAT

## NOTE FOR END USERS: DO NOT EDIT THIS FILE!
##
## This is a sample Matplotlib configuration file - you can find a copy
## of it on your system in site-packages/matplotlib/mpl-data/matplotlibrc
## (relative to your Python installation location).
## DO NOT EDIT IT!
##
## If you wish to change your default style, copy this file to one of the
## following locations:
##     Unix/Linux:
##         $HOME/.config/matplotlib/matplotlibrc OR
##         $XDG_CONFIG_HOME/matplotlib/matplotlibrc (if $XDG_CONFIG_HOME is set)
##     Other platforms:
##         $HOME/.matplotlib/matplotlibrc
## and edit that copy.
##
## See https://matplotlib.org/stable/tutorials/introductory/customizing.html#customizing-with-matplotlibrc-files
## for more details on the paths which are checked for the configuration file.
##
## Blank lines, or lines starting with a comment symbol, are ignored, as are
## trailing comments.  Other lines must have the format:
##     key: val  # optional comment
##
## Formatting: Use PEP8-like style (as enforced in the rest of the codebase).
## All lines start with an additional '#', so that removing all leading '#'s
## yields a valid style file.
##
## Colors: for the color values below, you can either use
##     - a Matplotlib color string, such as r, k, or b
##     - an RGB tuple, such as (1.0, 0.5, 0.0)
##     - a double-quoted hex string, such as "#ff00ff".
##       The unquoted string ff00ff is also supported for backward
##       compatibility, but is discouraged.
##     - a scalar grayscale intensity such as 0.75
##     - a legal html color name, e.g., red, blue, darkslategray
##
## String values may optionally be enclosed in double quotes, which allows
## using the comment character # in the string.
##
## This file (and other style files) must be encoded as utf-8.
##
## Matplotlib configuration are currently divided into following parts:
##     - BACKENDS
##     - LINES
##     - PATCHES
##     - HATCHES
##     - BOXPLOT
##     - FONT
##     - TEXT
##     - LaTeX

## The font properties used by `text.Text`.
## See https://matplotlib.org/api/font_manager_api.html for more information
## on font properties.  The 6 font properties used for font matching are
## given below with their default values.
##
## The font.family property can take either a single or multiple entries of any
## combination of concrete font names (not supported when rendering text with
## usetex) or the following five generic values:
##     - 'serif' (e.g., Times),
##     - 'sans-serif' (e.g., Helvetica),
##     - 'cursive' (e.g., Zapf-Chancery),
##     - 'fantasy' (e.g., Western), and
##     - 'monospace' (e.g., Courier).
## Each of these values has a corresponding default list of font names
## (font.serif, etc.); the first available font in the list is used.  Note that
## for font.serif, font.sans-serif, and font.monospace, the first element of
## the list (a DejaVu font) will always be used because DejaVu is shipped with
## Matplotlib and is thus guaranteed to be available; the other entries are
## left as examples of other possible values.
##
## The font.style property has three values: normal (or roman), italic
## or oblique.  The oblique style will be used for italic, if it is not
## present.
##
## The font.variant property has two values: normal or small-caps.  For
## TrueType fonts, which are scalable fonts, small-caps is equivalent
## to using a font size of 'smaller', or about 83%% of the current font
## size.
##
## The font.weight property has effectively 13 values: normal, bold,
## bolder, lighter, 100, 200, 300, ..., 900.  Normal is the same as
## 400, and bold is 700.  bolder and lighter are relative values with
## respect to the current weight.
##
## The font.stretch property has 11 values: ultra-condensed,
## extra-condensed, condensed, semi-condensed, normal, semi-expanded,
## expanded, extra-expanded, ultra-expanded, wider, and narrower.  This
## property is not currently implemented.
##
## The font.size property is the default font size for text, given in points.
## 10 pt is the standard value.
##
## Note that font.size controls default text sizes.  To configure
## special text sizes tick labels, axes, labels, title, etc., see the rc
## settings for axes and ticks.  Special text sizes can be defined
## relative to font.size, using the following values: xx-small, x-small,
## small, medium, large, x-large, xx-large, larger, or smaller

#font.family:  sans-serif
#font.style:   normal
#font.variant: normal
#font.weight:  normal
