Python 中的 Plotly 图表动画不正确

Plotly chart not animating properly in Python

我有一个相同的数据框 df,我在 Plotly 中设置了样式并创建了一个折线图。我添加了动画功能,但图表似乎出现错误。

   Size     Date        POD
   0.027289 11/1/2020   S 
   0.013563 11/1/2020   S 
   0.058498 11/1/2020   S 
   0.281953 11/1/2020   S 
   0.479725 11/1/2020   S

   0.208562 11/1/2020   S 
   0.013108 11/1/2020   S 

这就是我正在做的

 import plotly.express as px
 import plotly.graph_objects as go


 fig = px.scatter(df1, x = "Date", y = "Size", color = "POD",title = "POD Growth in US", 
 animation_frame="Date",
 log_x=True, size_max=55, range_x=[100,100000], range_y=[25,90],labels = {"Size": "Size in TB"})

 fig.update_layout(
 font_family="Arial",
 font_color="black",
 title_font_family="Arial",
 title_font_color="black",
 legend_title_font_color="black"
  )


fig.update_xaxes(title_font_family="Arial")

fig.update_layout(
title={
    'text': "POD Growth in US",
    'y':0.9,
    'x':0.5,
    'xanchor': 'center',
    'yanchor': 'top'})

 fig.update_traces(marker=dict(size=8,
    line=dict(width=1,
    color='DarkSlateGrey')),
    selector=dict(mode='markers'))

fig.show()

我认为问题出在这行代码中,但我不能 100% 确定我做错了什么:

 animation_frame="Date",
 log_x=True, size_max=55, range_x=[100,100000], range_y=[25,90]

我得到的错误:

  Invalid value of type 'pandas._libs.tslibs.timestamps.Timestamp' received for the 'name' property 
  of frame
  Received value: Timestamp('2020-09-01 00:00:00
  The 'name' property is a string and must be specified as:
  - A string
  - A number that will be converted to a string

我是否必须转换为“日期”列才能解决问题?

这是我想要制作动画的图表:

我不确定您的烛台动画是否会按预期 运行,但是将 DataFrame 的 Date 列从时间戳更改为字符串(使用日期时间库)应该可以解决该错误.

import datetime as dt

df1['Date'] = df1['Date'].map(lambda x: x.strftime('%m/%d/%Y'))
