The friends who followed in the early days should remember that I have written a lot of articles about seaborn and matplotlib. If you haven't read it, you can check it out:
Today's protagonist cufflinks is an advanced packaged version of plotly, just like the relationship between seaborn and matplotlib, it can visualize pandas DataFrame data very simply .

cufflinks color settings
Modify the color palette through the colorscale parameter;
Pass color numbers through colors, and support three types of color numbers:
HEX "#db4052"
RGB "rgb(219, 64, 82)"
RGBA "rgba(219, 64, 82, 1.0)"
#支持的调色盘
cf.colors.scales()
Import dependencies, standard settings
import cufflinks as cf
import pandas as pd
import numpy as np
%reload_ext autoreload
%autoreload 2
cf.set_config_file(world_readable=True,theme='henanigans',offline=False)#theme设置绘图风格，offline设置为true
2、cufflinks快速上手
cufflinks有一个很强大的函数iplot，可以很容易的将The visualization method of Pandas (see the previous part) is combined with the drawing method of Plotly and Cufflinks.
#还是使用iris数据集
import seaborn as sns
pd_iris = sns.load_dataset("iris")
pd_iris.head(n=5)
An example illustratesiplot的强大之处：
#Pandas可视化方法
pd_iris.head(n=5).plot(kind='bar')
#iplot结合pandas可视化方法与ploty方法
pd_iris.head(n=5).iplot(kind='bar',colorscale='set1')
-
Faceted histogram
#subplots绘制分面图
pd_iris.head(n=5).iplot(kind='bar',colorscale='set1',subplots=True)
-
Stacked histogram
pd_iris.head(n=5).iplot(kind='bar',colorscale='set1',barmode='stack')
-
