我一直試圖讓“

Python中的填充區(qū)域動畫”示例在Jupyter筆記本中以離線模式使用plotly工作.這個例子可以在這里找到：

https://plot.ly/python/filled-area-animation/

由于我處于離線模式,我創(chuàng)建了一個包含虛擬數(shù)據(jù)的本地csv文件作為數(shù)據(jù)源,然后使用pandas dataframes讀取csv：

# Add the following line

from plotly.offline import init_notebook_mode, iplot

.....

# Read csv instead of using get_data_yahoo

#appl = web.get_data_yahoo('AAPL', '2016-01-01', '2016-11-30')

appl = pd.read_csv("C:\\test.csv")

apple_data_matrix = appl.head(10)

.....

# Use offline version of iplot

#py.iplot(table, filename='apple_data_table')

iplot(table, filename='apple_data_table')

到現(xiàn)在為止還挺好.

“Make the Grid”的代碼保持不變 – 除了注釋掉僅在線的最后一行：

def to_unix_time(dt):

epoch = datetime.utcfromtimestamp(0)

return (dt - epoch).total_seconds() * 1000

appl_price = list(appl['Adj Close'])

my_columns = []

for k in range(len(appl.index) - 1):

my_columns.append(Column(appl.index[: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)

代碼的最后一部分(‘Make the figure’)是我在努力的地方.這是繪制圖表并為其設(shè)置動畫的代碼：

data=[dict(type='scatter',

xsrc=grid.get_column_reference('x1'),

ysrc= grid.get_column_reference('y1'),

name='AAPL',

mode='lines',

line=dict(color= 'rgb(114, 186, 59)'),

fill='tozeroy',

fillcolor='rgba(114, 186, 59, 0.5)')]

axis=dict(ticklen=4,

mirror=True,

zeroline=False,

showline=True,

autorange=False,

showgrid=False)

layout = dict(title='AAPL Daily Stock Price',

font=dict(family='Balto'),

showlegend=False,

autosize=False,

width=800,

height=400,

xaxis=dict(axis, **{'nticks':12, 'tickangle':-45,

'range': [to_unix_time(datetime(2016, 1, 4)),

to_unix_time(datetime(2016, 11, 30))]}),

yaxis=dict(axis, **{'title': '$', 'range':[0,120]}),

updatemenus=[dict(type='buttons',

showactive=False,

y=1,

x=1.1,

xanchor='right',

yanchor='top',

pad=dict(t=0, r=10),

buttons=[dict(label='Play',

method='animate',

args=[None, dict(frame=dict(duration=50, redraw=False),

transition=dict(duration=0),

fromcurrent=True,

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

frames=[{'data':[{'xsrc': grid.get_column_reference('x{}'.format(k + 1)),

'ysrc': grid.get_column_reference('y{}'.format(k + 1))}],

'traces': [0]

} for k in range(len(appl.index) - 1)]

fig=dict(data=data, layout=layout, frames=frames)

py.icreate_animations(fig, 'AAPL-stockprice' + str(time.time()))

py.icreate_animations(最后一行)在離線模式下不可用.我試過用plotly.offline.iplot替換它(圖),但得到以下堆棧跟蹤：

任何人都可以幫助鍛煉如何讓動畫在離線模式下工作.
