本 plotly 教程中的动画示例不适用于 Plotly 2.0.12。我将错误输出放在下面。有什么办法可以解决这个问题吗？我正在Jupyter笔记本上使用plotly。
PlotlyError: Invalid 'figure_or_data' argument. Plotly will not be
able to properly parse the resulting JSON. If you want to send this
'figure_or_data' to Plotly anyway (not recommended), you can set
'validate=False' as a plot option.
Here's why you're seeing this error:
'slider' is not allowed in 'layout'
Path To Error: ['layout']['slider']
Valid attributes for 'layout' at path ['layout'] under parents
['figure']:
['angularaxis', 'annotations', 'autosize', 'bargap', 'bargroupgap',
'barmode', 'barnorm', 'boxgap', 'boxgroupgap', 'boxmode', 'calendar',
'direction', 'dragmode', 'font', 'geo', 'height', 'hiddenlabels',
'hiddenlabelssrc', 'hidesources', 'hoverlabel', 'hovermode',
'images',
'legend', 'mapbox', 'margin', 'orientation', 'paper_bgcolor',
'plot_bgcolor', 'radialaxis', 'scene', 'separators', 'shapes',
'showlegend', 'sliders', 'smith', 'ternary', 'title', 'titlefont',
'updatemenus', 'width', 'xaxis', 'yaxis']
Run `<layout-object>.help('attribute')` on any of the above.
'<layout-object>' is the object at ['layout']

我不知道我是否必须降级版本(以及，以防万一，降级到哪个版本(，但我宁愿不降级。
我验证了您的代码并发现了一些错误。
- 在第 29 行你应该给
figure['layout']['sliders']而不是figure['layout']['slider']
- Plotly 离线的 iplot 函数有一个单独的参数来输入绘图的配置。
所以下面的一行
# make figure
figure = {
'data': [],
'layout': {},
'frames': [],
'config': {'scrollzoom': True}
}
和线
iplot(figure)
实际上应该写成
# make figure
figure = {
'data': [],
'layout': {},
'frames': []
}
config = {'scrollzoom': True}
和
iplot(figure, config=config)
所以最终的工作代码应该是
