Filled-Area Animation in Python/v3

How to make an animated filled-area plot with apple stock data in Python.

Note: this page is part of the documentation for version 3 of Plotly.py, which is not the most recent version.
See our Version 4 Migration Guide for information about how to upgrade.

New to Plotly?¶

Plotly's Python library is free and open source! Get started by downloading the client and reading the primer.
You can set up Plotly to work in online or offline mode, or in jupyter notebooks.
We also have a quick-reference cheatsheet (new!) to help you get started!

Version Check¶

Note: Animations are available in version 1.12.10+ Run pip install plotly --upgrade to update your Plotly version.

In [1]:

import plotly
plotly.__version__

Out[1]:

'1.12.12'

Import Data¶

Let us import some apple stock data for this animation.

In [1]:

import plotly.plotly as py
from plotly.grid_objs import Grid, Column
from plotly.tools import FigureFactory as FF

import time
from datetime import datetime
import numpy as np
import pandas as pd

appl = pd.read_csv('https://raw.githubusercontent.com/plotly/datasets/master/finance-charts-apple.csv')
appl.columns = [col.replace('AAPL.', '') for col in appl.columns]
apple_data_matrix = appl.head(10).round(2)

table = FF.create_table(apple_data_matrix)
py.iplot(table, filename='apple_data_table')

Out[1]:

Make the Grid¶

In [2]:

def to_unix_time(dt):
    epoch =  datetime.utcfromtimestamp(0)
    return (dt - epoch).total_seconds() * 1000

appl_price = list(appl['Adjusted'])
my_columns = []
for k in range(len(appl.Date) - 1):
    my_columns.append(Column(list(appl.Date)[:k + 1], 'x{}'.format(k + 1)))
    my_columns.append(Column(appl_price[:k + 1], 'y{}'.format(k + 1)))
grid = Grid(my_columns)
py.grid_ops.upload(grid, 'AAPL-daily-stock-price' + str(time.time()), auto_open=False)

Make the Figure¶
