Description
I created a forum post, describing the issue in full detail.
Basically, what I want is a logarithmic coloraxis for heatmaps, which is documented to work, but seems not to be implemented (in Plotly 2.35.3 nor 3.0.1).
Fixing the documentation would be the easiest solution, but implementing a logarithmic colorscale/colorbar according to the current (3.0.0) documentation should IMHO not be too hard and would add great value to plotly. (This feature was asked for multiple times in the plotly forums.)

Research direction
Start with the linked forum post and the layout/coloraxis colorbar documentation, then inspect how heatmaps handle coloraxis settings in Plotly.js 2.35.3 and 3.0.1. Clarify whether the documented logarithmic behavior should be implemented or the documentation corrected; done means the chosen behavior matches the published documentation and is verified for heatmaps.
