AnnotatedTimeLine's 'Lower Graph' Algorithm?

Please forgive my lack of insight, but I can't for the life of me
figure out how the AnnotatedTimeLine decides what to plot on the
'lower' graph - that which is bracketed by the Range Selector.

It's not the first data set (column)... it doesn't appear to be the
sum of all data columns for each time point... I'm just trying to
figure this out, and I'm afraid I'm a little stumped.

Alternatively, I'd *love* to be able to set what appears there - say
selecting data set (column) like I do when hiding/showing data
columns. Is there a way to do this?

If not, what's the logic behind what's displayed?

It feels oddly logarithmic to me.
I vote for an optional algorithm choice
of sub-interval min/max decimation.

It's the last [i.e. rightmost] data column, and I agree. :/

1. Its the last data series.

2. Its a logarithmic manipulation of this data.

3. We have an open feature request to let the users control this data.

4. For now, you can hide this part of the chart (displayRangeSelector: false). I know its not perfect, but for those who get crazy, it might be better than leaving it as is... :)
