I cant figure out the go.Mesh3d() reference

šŸ“Š Plotly Python
1

Hello,

I am quite new to programming, so I am sorry in advance if I am asking the wrong questions.
I was exploring the example for 3d meshing which was really helpful and decided to plot some volumes of my own.

I have been going thought the full reference and canā€™t make showing contour on hover work.

This is what I have tried: https://pastebin.com/NyzTE1qA

My plot works nicely except when i try to test what contour does. Then i get this error:

plotly.exceptions.PlotlyDictValueError: ā€˜contourā€™ has invalid value inside ā€˜mesh3dā€™

Path To Error: [ā€˜contourā€™]

Current path: []
Current parent object_names: []

With the current parents, ā€˜contourā€™ can be used as follows:

Under (ā€˜figureā€™, ā€˜dataā€™, ā€˜mesh3dā€™):

editType: calc
role: object

Thank you for your help!

Hi @predo,

Could you update your version of plotly.py (current version is 3.6.1 as of today) and post the new error message?

Thanks!

Yes it is solved and now the error message helps a lot by asking for a dictionary. Thank you very much for such a swift reply!

I am pasting the error message in case this comes up again for somebody else.

 The 'contour' property is an instance of Contour
    that may be specified as:
      - An instance of plotly.graph_objs.mesh3d.Contour
      - A dict of string/value properties that will be passed
        to the Contour constructor

        Supported dict properties:
            
            color
                Sets the color of the contour lines.
            show
                Sets whether or not dynamic contours are shown
                on hover
            width
                Sets the width of the contour lines.
