Feature summary (what you would like to be able to do and where):
GraphChart had the ability to define alternate y-axis scaling, such as log scaling.

Use case(s) (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution):
Data that grows on a non-linear basis is poorly represented on a linear scale. For example, revenue growth of a company is compound growth.

Benefits (why should this be implemented?):
Log scaling would more accurately visually represent data that grows at a faster than linear rate.
