Additive Chart Support about flot

[GoogleCodeExporter]

I think the appropriate way to do this is to add a dataset for the total 
production
in your own code. However you're already generating the data for each company, 
as you
go just keep track of whatever you're interested in.

I can empathize with your point, but I think I tend to agree with Ryan.

In any case, for anything to happen here, somebody needs to think up a 
reasonable API
that fits well in with the rest of Flot. That's the minimum requirement. :)

Offhand, to me, that sounds harder than simply summing up the stuff 
server-side. So
until this happens, I'll keep the bug closed as won'tfix.

OK, I'm going to reopen this. It's very similar to bug #31 which is about 
stacked 
bar charts specifically. There's two things in this: support for drawing areas 
where 
the lower part is not just the x axis, so to speak. And a preprocessor for 
accumulating the data. Let's make this bug about the latter thing.

Again what needs to happen here first is that someone thinks up a reasonable 
API.

I'd like to see:

yaxis : { mode: "stacked" }

Or something equally simplistic.  That would cause the data sets tied with the 
yaxis
to be drawn, in order, each stacked on the previous.  We use this now (in 
another
charting tool) to represent composition.  Think: bandwidth graph, but broken 
down by
protocol.  Or database transaction rates split into insert, update and delete.

Another option which is a bit more general would be specifying it in the series 
as
something like { data: [...], cumulativeGroup: 1 }. Flot would then accumulate 
the
series in the group, with the first series being at the bottom.

I think that all it takes to implement this is a bit of logic in processData. I 
think
we need to copy accumulated data series, though, otherwise it's not going to 
work
when people replot the same graph.

If I'm not mistaken, this was actually fixed some time ago with the stacked 
plugin,
although it might not be complete yet I don't think it makes sense to keep this 
open
anymore.
