Logarithmic colorbar in heatmaps not working as documented

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.)

先从链接的论坛帖子以及 layout/coloraxis colorbar 文档开始，然后检查 heatmap 在 Plotly.js 2.35.3 和 3.0.1 中如何处理 coloraxis 设置。明确应实现文档所述的对数行为，还是应修正文档；当所选行为与已发布的文档一致，并且已针对 heatmap 验证时，即视为完成。
