情节地，将纪元时间戳（以毫秒为单位）转换为可读的日期时间？

  • 772

下面的代码使用 Python 列表创建 Plotly 图表。

时间戳是 Epoch 毫秒。如何将 x 轴格式化为可读的日期时间？

我尝试过fig.layout['xaxis_tickformat'] = '%HH-%MM-%SS'，但没有成功。

import plotly.graph_objects as go

time_series = [1716693661000, 1716693662000, 1716693663000, 1716693664000]
prices = [20, 45, 32, 19]
 
fig = go.Figure()
fig.add_trace(go.Scatter(x=time_series, y=prices, yaxis='y'))

fig.update_layout(xaxis=dict(rangeslider=dict(visible=True),type="linear"))
fig.layout['xaxis_tickformat'] = '%Y-%m-%d'

fig.show()
python

    您可以fromtimestamp().strftime()从日期时间使用：

    tdt = [datetime.fromtimestamp(ts / 1000).strftime('%Y-%m-%d %H:%M:%S') for ts in time_series]

    代码

    

time_series = [1716693661000, 1716693662000, 1716693663000, 1716693664000]
prices = [20, 45, 32, 19]

tdt = [datetime.fromtimestamp(ts / 1000).strftime('%Y-%m-%d %H:%M:%S') for ts in time_series]

fig = go.Figure()
fig.add_trace(go.Scatter(x=tdt, y=prices, yaxis='y'))

fig.update_layout(
    xaxis=dict(
        rangeslider=dict(visible=True),
        type="date",
        tickformat='%Y-%m-%d %H:%M:%S'
    )
)

fig.show()
