Charts 
The Chart function was designed to facilitate the analysis
of an association by selective use of the 59 plus 6 ratios in the financial
profile, over the five years of historical plus the thirty years of forecast
data.
It is certainly easier and arguably more sensible to examine the future
projections, and thereby the underlying assumptions, in "broad-brush"
terms via graphical representation than by studying 35 columns of numbers.
Any particular ratio can be examined and printed off as a time-series
chart. The best way of carrying out good, focused analysis using the Chart
facility is to skim all the ratios then select maybe a dozen which capture
the key features of the financial profile over time for that particular
association and that particular scenario. It is probably better to study
these detailed charts after the Combined
Charts, which are based on some of the most important ratios.
These 35-year charts are also an excellent way of revealing, examining
and evaluating the effects of the underlying assumptions. It is easy to
get significant but unintended and maybe implausible "drift"
over 30 years in the "output variables" through the combination
of seemingly plausible input assumptions. The time-series charts are a
good way of picking up such forecasting 'errors'.
