我一直在尝试获取“Python中的填充区域动画”示例，以在Jupyter笔记本中以离线模式使用绘图功能来工作。可以在这里找到示例:https://plot.ly/python/filled-area-animation/
由于处于离线模式，因此我创建了一个本地csv文件，其中包含要用作数据源的伪数据，然后使用pandas数据帧读取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')
到现在为止还挺好。
“制作网格”的代码保持不变-除了注释仅在线的最后一行之外:
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)
代码的最后一部分(“图”)是我努力的地方。这是绘制图表并对其进行动画处理的代码:
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)在离线模式下不可用。我尝试用plotly.offline.iplot(fig)替换它，但是得到以下堆栈跟踪:

任何人都可以帮助锻炼如何使动画在离线模式下工作。
在此先感谢-西蒙
最佳答案
此问题已在中解决
Plotly icreate_animations offline on Jupyter Notebook
根据该答案，plotly.grid_objs Grid函数不支持脱机。他将代码转换为改为使用DataFrames，从而避免了该问题。
关于python - 在Jupyter中使用plotly在离线模式下创建动画图表，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/43058892/
