python Palettable库中颜色条Colormap使用


1、 palettable中colormap名称

palettable中颜色条分为16大类,每类中还有不同小类,共计1587种colormap

16大类

palettable.cartocolors.diverging
palettable.cartocolors.qualitative
palettable.cartocolors.sequential
palettable.cmocean.diverging
palettable.cmocean.sequential
palettable.colorbrewer.diverging
palettable.colorbrewer.qualitative
palettable.colorbrewer.sequential
palettable.lightbartlein.diverging
palettable.lightbartlein.sequential
palettable.scientific.diverging
palettable.scientific.sequential
palettable.matplotlib
palettable.mycarta
palettable.tableau
palettable.wesanderson

1587类

共计1587个colormap,其实每种色条还有对应的反向色条(ArmyRose_2的反向色条ArmyRose_2_r),感兴趣可以公众号后台索取。以下列出部分。

2、 palettable中colormap可视化

将所有的色条绘制了5张图,便于查阅,感兴趣可以公众号索取。 image

3、palettable中colormap属性

以palettable.colorbrewer.qualitative.Dark2_7为例

import palettes
from palettable.colorbrewer.qualitative import Dark2_7_r,Dark2_7
print(Dark2_7.name)#The name of the palette
print(type(Dark2_7))#'diverging', 'qualitative' and so on
print(Dark2_7.number)#number of defined colors 
print(Dark2_7.colors)# a list of RGB tuples in the range 0-255.
print(type(Dark2_7.colors))
print(Dark2_7.hex_colors)#a list of hex strings (e.g. '#A912F4')
print(Dark2_7.mpl_colors)#RGB tuples in the range 0-1 as used by matplotlib
print(Dark2_7.mpl_colormap)#
Dark2_7.show_discrete_image()#Dark2_7各种颜色条图片
Dark2_7_r.show_discrete_image()#Dark2_7_r各种颜色离散型图片
Dark2_7.show_continuous_image()#Dark2_7各种颜色连续型型图片
Dark2_7.save_discrete_image('Dark2_7.jpg')#保存图片
Dark2_7.save_continuous_image('Dark2_7c.jpg')#保存图片

4、palettable中colormap使用

以palettable.colorbrewer.qualitative.Dark2_7为例。Dark2_7的色条是什么样的? image
import palettable
import matplotlib.pyplot as plt
plt.figure(dpi=150)


#取palettable包中颜色
#取一种颜色
plt.subplot(1,2,1)
plt.bar(range(5),range(1,6),color=palettable.colorbrewer.qualitative.Dark2_7.mpl_colors[3])

#取多种颜色
plt.subplot(1,2,2)
plt.bar(range(5),range(1,6),color=palettable.colorbrewer.qualitative.Dark2_7.mpl_colors)
image
