A Python library called plotly is used to make graphs, especially interactive graphs. It can make graphs and charts like histograms, barplots, boxplots, spreadplots, and many more. It is mostly used for data analysis and analysis of money. plotly is a library for making interactive charts and graphs.
Cufflink links plotly to pandas so that graphs and charts can be made directly from dataframes. The word "choropleth" is used to describe a map of the United States. Choropleth is used to make world maps and many other things.
Example:
Setting up a dataframe with pandas and numpy library.
import pandas as pd
import numpy as np
%matplotlib inline
#import plotly and cufflinks
from plotly import __version__
import cufflinks as cf
#DATA
df = pd.DataFrame(np.random.randn(100,4),columns='A B C D'.split())
df.head()
df2 = pd.DataFrame({'Category':['A','B','C'],'Values':[32,43,50]})
Output:
Scatter Plot
df.iplot(kind='scatter',x='A',y='B',mode='markers')
Output:
The term "interactive plot" refers to iplot. Plotly reads code written in Python and generates charts written in JavaScript that look stunning. You can zoom in to take out values and you can also zoom out and also use tools available.
Bar Plot
df2.iplot(kind='bar',x='Category',y='Values')
Output:
Box Plot
df.iplot(kind='box')
Output:
Surface Plot:
df3=pd.DataFrame({'x':[1,2,3,4,5],'y':[10,20,30,40,50],'z':[5,4,3,2,1]})
df3.iplot(kind='surface',colorscale='rdylbu')
Output:
Histogram
df['A'].iplot(kind='hist',bins=50)
Output:
Spread Plot
df[['A','B']].iplot(kind='spread')
Output:
It is quite essential for stock datas to see the spread between 2 datas.
Bubble Plot
df.iplot(kind='bubble',x='A',y='B',size='C')
Output:
Scatter matrix
df.scatter_matrix()
Output:
With scatter matrix you may need to be careful when dealing with large data as this might take a while to load. And you might even crash your python kernal.
