After a bit of investigation, I suspect the hovertext array of surfacecolor has been transposed (why?). So I come up with a work around by adding a dummy customdata which is a transposed version of original surface array. And then we can just displaying customdata in the hovertext instead.
import numpy as np
import plotly.graph_objects as go
import pandas as pd
# Read data from a csv
z_data = pd.read_csv('https://raw.githubusercontent.com/plotly/datasets/master/api_docs/mt_bruno_elevation.csv')
fig = go.Figure(data=[
go.Surface(
z=z_data.values,
surfacecolor=z_data.values,
customdata=z_data.values.T,
hovertemplate='x=%{x}, y=%{y}<br>z=%{z}<br>surfacecolor=%{customdata}')])
fig.update_layout(title='Mt Bruno Elevation', autosize=False,
width=500, height=500,
margin=dict(l=65, r=50, b=65, t=90))
fig.show()
From the above image, I use the Mt. Bruno's _zdata for both z axis and surfacecolor. The surface graph is correct, but the hover text of surfacecolor is wrong. The correct surfacecolor text should be 372.8826 same as z's text.
