### What is the logarithmic color scales?(not logarithmic axes) [duplicate]

I have some density plots and an "advise". What does it mean? " I also strongly recommend switching the color scales in this figure from linear to log, to make it even easier to see the region of ...

### How can I make a density plot (or contour plot) with an arbitrary nonlinear scale (e.g. arcsinh, log, biexponential)?

I was inspired by this question, which showed how we can apply logarithmic scaling to a density plot. But I'm not always a fan of a logarithmic scale - it tends to overemphasize smaller features. ...
