A customer in the support forums suggests separating axis and scale concepts:

> The conceptualization of TeeChart might be enhanced if the notions of axis and scale were separated. When a series (say, temperatures on dates) is plotted, there must be vertical & horizontal axes with minima and maxima, to determine what temperatures are too low or too high, and what dates are too early or too late, to plot. After those limits are imposed, however, the user should be able to see multiple scales (say, Fahrenheit & Celsius, or calendar date & day of year) to help interpret the data.

See his example attached.

> I have further tweaked my implementation. Now it allows the outlying scales to be arbitrarily computed from the parent axes
