I've been trying to get the "Filled-Area Animation in Python" example to work using plotly in offline mode in a Jupyter notebook. The example can be found here: https://plot.ly/python/filled-area-animation/
Since I'm in off-line mode, I create a local csv file containing dummy data to use as the data source, then read the csv using pandas dataframes:
# 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')
So far so good. The code to "Make the Grid" remains the same - except commenting out the last line which is on-line only:
def to_unix_time(dt):epoch = datetime.utcfromtimestamp(0)return (dt - epoch).total_seconds() * 1000appl_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)
The final section of the code ('Make the figure') is where I'm struggling. This is the code which draws the chart and animates it:
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 (last line) is not available in off-line mode. I've tried replacing it with plotly.offline.iplot(fig) but get the following stack trace:

Can anyone help workout how to get the animation to work in offline mode.
Thanks in advance -- Simon
