This is indeed a complex visualization.
What is missing are two things: the smooth bezier-like curve, and the grouped histogram.
Do you really need such a graph for now? What can we do as an incremental step?
The example of high-level charts was supposed to show the treatment of negative values, I
do not expect Grapher to provide the same features and have the same look n feel as the
library which has been developed since 2009.
I think what you did with double graph builder should be sufficient. I'll have a
detailed look a bit later. One nice thing with the double graph builder is to provide an
API to normalize values so that bigger values do not mask the smaller onces.
Thank you.

Ok, this is something that should be easy to have.
I have a question, how this should behave with negative X and Y values?
I do not see why that would be problematic or may be I am missing a point.
I played a bit with HighCharts to see how does it behave in the presence of negative
values in combo charts (I edited the examples in js fidle).

This is what I obtained pretty much according to my expectations:

Hi Alex,
In Eyesee, we have the concept of composite diagrams i.e. you can have multiple charts in
the same diagram with individual y axes (see attached screenshot). This is a handy concept
because not only you could have two charts on the same diagram but each chart has its own
axis. For comparing disparate values, this is convenient because one does not need to
think about normalizing Y values of charts to the same scale. One example could be showing
trends of software metrics over time.
I saw that you ported more code from Charter to Grapher so I am having a look at the
examples. Is it possible to have composite chart diagrams with Grapher? Do you plan to add
this feature?
Here is a exemplary script that illustrates the need for composite diagrams:
| grapher minDate ds random dates grapherBlock|
dates := (Array with: Date today with: Date yesterday with: Date tomorrow) collect:
#asDateAndTime.
minDate := dates min.
random := Random seed: 10.
grapher := RTGrapherBuilder new
extent: 300 @ 200;
yourself.
grapherBlock := [:index |
ds := RTDataSet new.
ds interaction popup.
ds dotShape ellipse color: (Color red alpha: 0.5); size: 10.
ds points: dates sorted;
x: [ :aDate | aDate asUnixTime - minDate asUnixTime ];
connectColor: (Color random alpha: 0.5);
y: [ :d | (random nextInt: 100) * index].
grapher add: ds].
100 to: 103 do: grapherBlock.
1 to: 3 do: grapherBlock.
grapher axisConfiguration noDecimals.
grapher axisY.
grapher axisConfiguration
labelRotation: -30;
title: '';
numberOfLabels: dates size - 1;
labelConvertion: [ :v | (DateAndTime fromUnixTime: v + minDate asUnixTime)
asDate ] .
grapher axisX; build.
grapher view open
