farrow-and-ball 0.0.3

Port of the R farrowandball palette implementation.

Farrow&Ball Matplotlib

This is a python port for the matplotlib library of the R Package for ggplot2.

The style for the charts is provided in the styles folder

Installation

A python version >= 3 is required.

pip install farrow-and-ball

Usage

The usage is quite simple:

from farrow_and_ball import *
import numpy as np
import matplotlib.pyplot as plt

# Define a gray scale image
x = np.arange(0, np.pi, 0.1)
y = np.arange(0, 2 * np.pi, 0.1)
X, Y = np.meshgrid(x, y)
Z = np.cos(X) * np.sin(Y) * 10

# Get the color map
cmap = build_colormap(DivergentPalette.DAY, True)

# Draw image
plt.imshow(Z, origin="lower", cmap=cmap)
plt.show()

One can also directly get the color map definition as a list of strings with farrow_and_ball.get_palette(DivergentPalette.DAY) or an interpolated one with farrow_and_ball.get_interpolated_palette(DivergentPalette.DAY, num_classes).

Palettes

The palettes are organized in Enums:

class SpectralPalette(Enum):
    DEEPSPEC = "deepspec"
    SPEC = "spec"
    LIGHTSPEC = "lightspec"
    LIGHTERSPEC = "lighterspec"


class DivergentPalette(Enum):
    DAY = "day"
    DAYLONG = "daylong"
    ARMY = "army"
    MONO = "mono"


class BaseColorPalette(Enum):
    PINKS = "pinks"
    PINKS_VAR = "pinks2"
    REDS = "reds"
    YELLOWS = "yellows"
    GREENS = "greens"
    GREENS_VAR = "greens2"
    BLUES = "blues"
    BLUES_VAR = "blues2"


class MiscPalette(Enum):
    TONKA = "tonka"
    BELLSPOUT = "bellsprout"
    DOCKERS = "dockers"
    FRUITYPEBBLES = "fruitypebbles"

One can also directly enter the name as a string, e.g. build_colormap("day", True).
