Summary:
Ref T13279. See PHI1491. Currently, the top-level "Burnup Rate" chart in Maniphest shows total created tasks above the X-axis, without adjusting for closures.
This is unintended and not very useful. The filtered-by-project charts show the right value (cumulative open tasks, i.e. open minus close). Change the value to aggregate creation events and status change events.
Test Plan: Viewed top-level chart, saw the value no longer monotonically increasing.

Summary:
Depends on D20818. Ref T13279. The behavior of the "burndown" chart has wandered fairly far afield; make it look more like a burndown.
Move the other thing into an "Activity" chart.

Summary:
Ref T13279. Allow engines to choose how areas in a stacked area chart stack on top of one another.
This could also be accomplished by using multiple stacked area datasets, but datasets would still need to know if they're stacking "up" or "down" so it's probably about the same at the end of the day.

Summary: Ref T13279. Fix some tabular stuff, draw areas better, make the "compose()" API more consistent, unfatal the demo chart, unfatal the project burndown, make the project chart do something roughly physical.
Test Plan: Looked at charts, saw fewer obvious horrors.

Summary:
Depends on D20814. Currently, "min()" and "max()" are still "min(f, n)". This is no longer consistent with the construction of functions a function-generators that are composed at top level.
Turn them into "min(n)" and "max(n)" (i.e., not higher-order functions).
Then, mark all the functions which are pure mathematical functions and not higher-order as "pure". These functions have no function parameters and do not reference external data. For now, this distinction has no immediate implications, but it will simplify the next change (which tracks where data came from when it originated from an external source -- these pure functions never have any source information, since they only apply pure mathematical transformations to data).
Test Plan: Loaded a burnup chart, nothing seemed obviously broken.

Summary:
Ref T13279. See that task for some discussion.
The accumulations of some of the datasets may be negative (e.g., if more tasks are moved out of a project than into it) which can lead to negative area in the stacked chart.
Introduce `min(...)` and `max(...)` to separate a function into points above or below some line, then mangle the areas to pick the negative and positive regions apart so they at least have a plausible physical interpretation and none of the areas are negative.
This is presumably not a final version, I'm just trying to produce a chart that isn't a sequence of overlapping regions with negative areas that is "technically" correct but not really possible to interpret.

Differential Revision: https://secure.phabricator.com/D20506
Summary:
Ref T13279. Currently, we store a fairly low-level description of functions and datasets in a chart. This will create problems with (for example) translating function labels.
If you view a chart someone links you, it should say "El Charto" if you speak Spanish, not "The Chart" if the original viewer speaks English.
To support this, store a slightly higher level version of the chart: the chart engine key, plus configuration parameters. This is very similar to how SearchEngine works.
For example, the burndown chart now stores a list of project PHIDs, instead of a list of `[accumulate [sum [fact task.open <project-phid>]]]` functions.
(This leaves some serialization code with no callsites, but we may eventually have a "CustomChartEngine" which stores raw functions, so I'm leaving it for now.)
As a result, function labels provided by the chart engine are now translatable.
(Note that the actual chart is meaningless since the underlying facts can't be stacked like they're being stacked, as some are negative in some areas of their accumulation.)

Summary:
Ref T13279. This adds support for:
- Datasets can have types, like "stacked area".
- Datasets can have multiple functions.
- Charts can store dataset types and datasets with multiple functions.
- Adds a "stacked area" dataset.
- Makes D3 actually draw a stacked area chart.
Lots of rough edges here still, but the result looks slightly more like it's supposed to look.
D3 can do some of this logic itself, like adding up the area stacks on top of one another with `d3.stack()`. I'm doing it in PHP instead because I think it's a bit easier to debug, and it gives us more options for things like caching or "export to CSV" or "export to API" or rendering a data table under the chart or whatever.

Summary:
Ref T13279. For now, we need to render burndowns from both Maniphest (legacy) and Projects (new prototype).
Consolidate this logic into a "BurndownChartEngine". I plan to expand this to work a bit like a "SearchEngine", and serve as a UI layer on top of the raw chart features.
The old "ChartEngine" is now "ChartRenderingEngine".
Test Plan:
- Viewed burndowns ("burnups") in Maniphest.
- Viewed burndowns in Projects.
- Saw the same chart.
