Scale Range does not work correctly if Log scale is applied.

Problem:

Scale Range does not work correctly if Log scale is applied.


Solution:


In the line chart visualization, if you have multiple Y-axis with "Multiple scales" enabled and you want all Y-axis to have same range, you will need to right click on Visualization, select "Properties">"Y-axis" and select the "Scale Range" button and set the range. Note that this may not work if Log Scale is applied on Scale Range having a range 0-100.

Resolution

The reason why the Y-axis will not have same range if Log Scale is applied on Scale Range 0-100 is Log(0) is undefined. Refrain from using "0" in the scale range when using Log Scale.
