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).

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.

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:
Depends on D20446. Currently, chart functions are both configured through arguments and evaluated through arguments. This sort of conflates things and makes some logic more difficult than it should be.
Instead:
- Function arguments are used to configure function behavior. For example, `scale(2)` configures a function which does `f(x) => 2 * x`.
- Evaluation is now separate, after configuration.
We can get rid of "sourceFunction" (which was basically marking one argument as "this is the thing that gets piped in" in a weird magical way) and "canEvaluate()" and "impulse".
Sequences of functions are achieved with `compose(u, v, w)`, which configures a function `f(x) => w(v(u(x)))` (note order is left-to right, like piping `x | u | v | w` to produce `y`).
The new flow is:
- Every chartable function is `compose(...)` at top level, and composes one or more functions. `compose(x)` is longhand for `id(x)`. This just gives us a root/anchor node.
- Figure out a domain, through various means.
- Ask the function for a list of good input X values in that domain. This lets function chains which include a "fact" with distinct datapoints tell us that we should evaluate those datapoints.
- Pipe those X values through the function.
- We get Y values out.
- Draw those points.
Also:
- Adds `accumluate()`.
- Adds `sum()`, which is now easy to implement.
- Adds `compose()`.
- All functions can now always evaluate everywhere, they just return `null` if they are not defined at a given X.
- Adds repeatable arguments for `compose(f, g, ...)` and `sum(f, g, ...)`.

Summary:
Depends on D20445. Ref T13279. I'm not sure what the class tree of functions actually looks like, and I suspect it isn't really a tree, so I'm hesitant to start subclassing. Instead, try adding some `isSomethingSomething()` methods.
We have some different types of functions:
# Some functions can be evaluated anywhere, like "constant(3)", which always evaluates to 3.
# Some functions can't be evaluated anywhere, but have values everywhere in some domain. This is most interesting functions, like "number of open tasks". These functions also usually have a distinct set of interesting points, and are constant between those points (any count of anything, like "open points in project" or "tasks closed by alice", etc).
# Some functions can be evaluated almost nowhere and have only discrete values. This is most of the data we actually store, which is just "+1" when a task is opened and "-1" when a task is closed.
Soon, I'd like to be able to show ("all tasks" - "open tasks") and draw a chart of closed tasks. This is somewhat tricky because the two datasets are of the second class of function (straight lines connecting dots) but their "interesting" x values won't be the same (users don't open and close tasks every second, or at the same time).
The "subtract X Y" function will need to be able to know that `subtract "all tasks" 3` and `subtract "all tasks" "closed tasks"` evaluate slightly differently.
To make this worse, the data we actually //store// is of the third class of function (just the "derivative" of the line chart), then we accumulate it in the application after we pull it out of the database. So the code will need to know that `subtract "derivative of all tasks" "derivative of closed tasks"` is meaningless, or the UI needs to make that clear, or it needs to interpret it to mean "accumulate the derivative into a line first".
Anyway, I'll sort that out in future changes. For now, simplify the easy case of functions in class (1), where they're just actual functions.
Add "shift(function, number)" and "scale(function, number)". These are probably like "mul" and "add" but they can't take two functions -- the second value must always be a constant. Maybe these will go away in the future and become `add(function, constant(3))` or something?

The range of the chart is locked to "[0, 105% of max]". This is trying to make a pleasing extra margin above the maximum value, but currently just breaks charts with negative values. Later:
- I'll probably let users customize this.
- We should likely select 0 as the automatic minimum for charts with no negative values.
- For charts with positive values, it would be nice to automatically pick a pleasantly round number (25, 100, 1000) as a maximum by default.
We don't have any storage for charts yet. Add some. This works like queries, where every possible configuration gets a short URL slug. Nothing writes or reads this yet.
Rename `fn()` to `css_function()`. This builds CSS functions for D3. The JS is likely to get substantial structural rewrites later on, `fn()` was just particularly offensive.

Ref T13083. Facts has a fair amount of weird hardcoding and duplication of responsibilities. Reduce this somewhat: no more hard-coded fact aggregates, no more database-driven list of available facts, etc. Generally, derive all objective truth from FactEngines. This is more similar to how most other modern applications work.
For clarity, hopefully: rename "FactSpec" to "Fact". Rename "RawFact" to "Datapoint".
Split the fairly optimistic "RawFact" table into an "IntDatapoint" table with less stuff in it, then dimension tables for the object PHIDs and key names. This is primarily aimed at reducing the row size of each datapoint. At the time I originally wrote this code we hadn't experimented much with storing similar data in multiple tables, but this is now more common and has worked well elsewhere (CustomFields, Edges, Ferret) so I don't anticipate this causing issues. If we need more complex or multidimension/multivalue tables later we can accommodate them. The queries a single table supports (like "all facts of all kinds in some time window") don't make any sense as far as I can tell and could likely be UNION ALL'd anyway.
Remove all the aggregation stuff for now, it's not really clear to me what this should look like.
