Python 3.x 使用Plotly python打印后防止相机重置
我正在尝试使用dash和plotly为3d箭袋或圆锥体绘制一些数据,我希望通过间隔输入定期更新图形 因此,我设法制作了图形动画,但问题是每次更新后,相机角度和缩放都会重新设置。 我有以下代码:Python 3.x 使用Plotly python打印后防止相机重置,python-3.x,plotly-dash,plotly-python,Python 3.x,Plotly Dash,Plotly Python,我正在尝试使用dash和plotly为3d箭袋或圆锥体绘制一些数据,我希望通过间隔输入定期更新图形 因此,我设法制作了图形动画,但问题是每次更新后,相机角度和缩放都会重新设置。 我有以下代码: import dash import dash_core_components as dcc import dash_html_components as html import plotly.graph_objs as go from dash.dependencies import Output, I

有人知道如何避免这个问题吗?
理想情况下,我希望在不重新绘制整个帧的情况下更新数据,类似于matplotlib中的“set_data”。否则,是否有方法跟踪最新的摄影机角度并通过回调更新布局?
谢谢^ ^是的,您可以使用
uirevision
属性,如下所述:您实际上可以将uirevision设置为任何内容,只要您不更改它:)
