Can the vertical axis of a plot be configured to have log log scaling?

Hello,
I’m trying to find software that can plot oil viscosities that follow something called the Walther Equation.

This plots a straight line when the vertical axis is a double log scale.
This is the standard scaling applied to the ASTM D 341-17 chart for plotting viscosities.
Does this software have the ability to set up a vertical axis with this log log scaling?
Thanks for the help,
Andy

Thank you for taking the time to demonstrate this command. As I feared, the vertical data no longer corelates to the original viscosity value. What you've shown is useful for comparing slopes of lines, but not quite what I need for analyzing a specific fluid's temperature/viscosity performance.
I'll try to look at the video, though. Maybe there are other insights.
Thanks!

LL = log10(viscosity);
semilogy(x,LL);
??

Was a solution to this problem found? I am trying to determine something similar.
