【问题描述】：
我想画各种各样的立方体， 所以引用了以下链接：
SAMPLE1：https://plotly.com/python/3d-mesh/#mesh-cube
示例 2：https://plotly.com/python/3d-subplots/#3d-surface-subplots
接口：https://plotly.com/python-api-reference/generated/plotly.subplots.make_subplots.html
稍作改动以从 json 获取 x,y,z 位置参数。
然后在下面写代码。为什么不工作并提前感谢。

The 'data' property is a tuple of trace instances
that may be specified as:
- A list or tuple of trace instances
(e.g. [Scatter(...), Bar(...)])
- A single trace instance
(e.g. Scatter(...), Bar(...), etc.)
- A list or tuple of dicts of string/value properties where:
- The 'type' property specifies the trace type
One of: ['area', 'bar', 'barpolar', 'box',
'candlestick', 'carpet', 'choropleth',
'choroplethmapbox', 'cone', 'contour',
'contourcarpet', 'densitymapbox', 'funnel',
'funnelarea', 'heatmap', 'heatmapgl',

'isosurface', 'mesh3d', 'ohlc', 'parcats',
'parcoords', 'pie', 'pointcloud', 'sankey',
'scatter', 'scatter3d', 'scattercarpet',
'scattergeo', 'scattergl', 'scattermapbox',
'scatterpolar', 'scatterpolargl',
'scatterternary', 'splom', 'streamtube',
'sunburst', 'surface', 'table', 'treemap',
'violin', 'volume', 'waterfall']
- All remaining properties are passed to the constructor of
the specified trace type
(e.g. [{'type': 'scatter', ...}, {'type': 'bar, ...}])
【问题讨论】：
-
这一行：
cols = row + math.ceil((len(_i)%row)/row)->row未定义。 -
@EricLavault 感谢您的指出。我修复了它然后得到了我一直遇到的错误。
