Colormap Issue when using create_trisurf... list index out of range

[jjmason687]

Hi,

I’ve fairly new to using plotly but I managed to create a plot using the create_trisurf function in the plotly.express library. It was working for a while but recently stopped giving me the attached errors. It seems like there might be something wrong with how I’m choosing the colormap, which I definitely did not change. I’m not sure if this is the result of an update or change. Any help would be appreciated.

hi @jjmason687
welcome to the community.

Did you happen to install a newer version of Plotly recently? Did you change anything in the code or this graph just stopped working?

ff.create_trisurf is an obsolete method to generate such a surface. Now trisurfs can be generated as go.Mesh3d traces.
You can find a few examples in this notebook https://chart-studio.plotly.com/~empet/15522.
