Option to plot intensity in the heatmap on the logarithmic scale

[tbragin]

When visualizing a heatmap over multiple geo location points, where concentration of counts is very different (e.g. orders of magnitude), heatmap becomes almost invisible in locations with low counts. For example, if NY has n servers, London has m servers and HK has h servers, where n is far greater than m, and m is far greater than h, heatmap makes h invisible. One idea is to visualize heatmap using log10 transform on the data points.

To get the discussion going... Do others face this issue? Any other ideas on how to address it?

We also have the same problem.
Our Webservers experience heavy traffic from locations where our carsharing business is running, as well as a little traffic distributed over other places.
Those "other places" are almost invisble, depending on the other settings of the visualization.

I'll check if I'm allowed to post a screenshot of our board.

Closing this issue because this is supported in Lens visualizations. You can define a custom color ramp on heatmaps using a logarithmic scale.

Since this would require a large development effort to implement in Visualize/TSVB and our efforts are focused on extending the functionality of Lens in easy-to-use and consistent way. We aim to provide the best possible visualization editing experience in Lens and are working to improve that tool and help users migrate.
