Research direction

Open the matplotlib_to_plotly() example at the linked Plotly documentation page and reproduce the reported TypeError. Compare the cmap_rgb conversion with the one-line change described in the issue; done means the documented example runs without the TypeError.

Description

Hi,

The example code in matplotlib_to_plotly() (https://plotly.com/python/v3/matplotlib-colorscales/) doesn't work due to a TypeError.

Anyway, I am sure that the argument meant to be passed to this function is the [colorscale]_rgb list ... which again throws a TypeError, but this can be fixed by editing one line:

C = list(map(np.uint8, np.array(cmap_rgb[k])*255))

Then it works.
