Filled Area Animation - Plotly Py

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.

Import Data

Let us import some apple stock data for this animation.

python

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')

Make the Grid

python

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

python

data=[dict(type='scatter',
           xsrc=grid.get_column_reference('x1'),
           ysrc= grid.get_column_reference('y1'),

                                                               mode='immediate')])])])

         'traces': [0]
        } for k in range(len(appl.Date) - 1)]

fig=dict(data=data, layout=layout, frames=frames)
py.icreate_animations(fig, 'AAPL-stockprice' + str(time.time()))
