Tyler Goodlet cfd3ff6527 Don't unset `Viz.render` for unit vlm
Such that we still y-range auto-sort inside
`ChartView.interact_graphics_cycle()` still runs on the unit vlm axis
and we always size such that the y-label stays in view.

Tyler Goodlet 264d21d59e Move axis hiding into `.overlay_plotitem()`
Since we pretty much always want the 'bottom' and any side that is not
declared by the caller move the axis hides into this method. Lets us
drop the same calls in `.ui._fsp` and `._display`.

This also disables the auto-ranging back-linking for now since it
doesn't seem to be working quite yet?

Tyler Goodlet 63e705bab0 Better handle dynamic registry sampler broadcasts
In situations where clients are (dynamically) subscribing *while*
broadcasts are starting to taking place we need to handle the
`set`-modified-during-iteration case. This scenario seems to be more
common during races on concurrent startup of multiple symbols. The
solution here is to use another set to take note of subscribers which
are successfully sent-to and then skipping them on re-try.

This also contains an attempt to exception-handle throttled stream
overruns caused by higher frequency feeds (like binance) pushing more
quotes then can be handled during (UI) client startup.

Tyler Goodlet d6a8d779cf Lul, actually scaled main chart from linked set
This was a subtle logic error when building the `plots: dict` we weren't
adding the "main (ohlc or other source) chart" from the `LinkedSplits`
set when interacting with some sub-chart from `.subplots`..

Further this tries out bypassing `numpy.median()` altogether by just
using `median = (ymx - ymn) / 2` which should be nearly the same?

Tyler Goodlet b8d94bd337 Use `._pathops.slice_from_time()` for overlay intersects
It's way faster since it uses a uniform time arithmetic to narrow the
`numpy.searchsorted()` range before actually doing the index search B)

Tyler Goodlet 69b79191f1 Don't scale overlays on linked from display loop
In the (incrementally updated) display loop we have range logic that is
incrementally updated in real-time by streams, as such we don't really
need to update all linked chart's (for any given, currently updated
chart) y-ranges on calls of each separate (sub-)chart's
`ChartView.interact_graphics_cycle()`. In practise there are plenty of
cases where resizing in one chart (say the vlm fsps sub-plot) requires
a y-range re-calc but not in the OHLC price chart. Therefore
we always avoid doing more resizing then necessary despite it resulting
in potentially more method call overhead (which will later be justified
by better leveraging incrementally updated `Viz.maxmin()` and
`media_from_range()` calcs).

Tyler Goodlet 5e6e2f8925 Add `Viz.median_from_range()`
A super snappy `numpy.median()` calculator (per input range) which we

things on mutable types XD

Tyler Goodlet 0932a85c9f Speed up ranging in display loop
use the new `do_overlay_scaling: bool` since we know each feed will have
its own updates (cuz multiplexed by feed..) and we can avoid
ranging/scaling overlays that will make their own calls.

Also, pass in the last datum "brighter" color for ohlc curves as it was
originally (and now that we can pass that styling bit through).

Tyler Goodlet ea913e160d Fix intersect detection using time indexing
Facepalm, obviously absolute array indexes are not going to necessarily
align vs. time over multiple feeds/history. Instead use
`np.searchsorted()` on whatever curve has the smallest support and find
the appropriate index of intersection in time so that alignment always
starts at a sensible reference.

Also adds a `debug_print: bool` input arg which can enable all the
prints when working on this.

Tyler Goodlet a9670a85e8 Factor curve-dispersion sorting into primary loop
We can determine the major curve (in view) in the first pass of all
`Viz`s so drop the 2nd loop and thus the `mxmn_groups: dict`. Also
simplifies logic for the case of only one (the major) curve in view.

Tyler Goodlet 8a5fe9da79 Only set the major curve's range once (per render cycle)
Turns out this is a limitation of the `ViewBox.setYRange()` api: you
can't call it more then once and expect anything but the first call to
be applied without letting a render cycle run. As such, we wait until
the end of the log-linear scaling loop to finally apply the major curves
y-mx/mn after all minor curves have been evaluated.

This also drops all the debug prints (for now) to get a feel for latency
in production mode.

Tyler Goodlet 70baf6db0c Drop `.group_maxmin()`
We ended up doing groups maxmin sorting at the interaction layer (new
the view box) and thus this method is no longer needed, though it was
the reference for the code now in `ChartView.interact_graphics_cycle()`.

Further this adds a `remove_axes: bool` arg to `.insert_plotitem()`
which can be used to drop axis entries from the inserted pi (though it
doesn't seem like we really ever need that?) and does the removal in
a separate loop to avoid removing axes before they are registered in
`ComposedGridLayout._pi2axes`.

Tyler Goodlet 520905a653 Clean up cross-curve intersect point indexing
When there are `N`-curves we need to consider the smallest
x-data-support subset when figuring out for each major-minor pair such
that the "shorter" series is always returns aligned to the longer one.

This makes the var naming more explicit with `major/minor_i_start` as
well as clarifies more stringently a bunch of other variables and
explicitly uses the `minor_y_intersect` y value in the scaling transform
calcs. Also fixes some debug prints.

Tyler Goodlet b3ca8d83a6 3rdz the charm: log-linearize minor y-ranges to a major
In very close manner to the original (gut instinct) attempt, this
properly (y-axis-vertically) aligns and scales overlaid curves according
to what we are calling a "log-linearized y-range multi-plot" B)

The basic idea is that a simple returns measure (eg. `R = (p1 - p0)
/ p0`) applied to all curves gives a constant output `R` no matter the
price co-domain in use and thus gives a constant returns over all assets
in view styled scaling; a intuitive visual of returns correlation. The
reference point is for now the left-most point in view (or highest
common index available to all curves), though we can make this
a parameter based on user needs.

A slew of debug `print()`s are left in for now until we iron out the
remaining edge cases to do with re-scaling a major (dispersion) curve
based on a minor now requiring a larger log-linear y-range from that
previous major' range.

Tyler Goodlet 9b321bc7f1 2nd try: dispersion normalize y-ranges around median
In the dispersion swing calcs, use the series median from the in-view
data to determine swing proportions to apply on each "minor curve"
(series with lesser dispersion the one with the greatest). Track the
major `Viz` as before by max dispersion. Apply the dispersion swing
proportions to each minor curve-series in a third loop/pass of all
overlay groups: this ensures all overlays are dispersion normalized in
their ranges but, minor curves are currently (vertically) centered (vs.
the major) via their medians.

There is a ton of commented code from attempts to try and vertically
align minor curves to the major via the "first datum" in-view/available.
This still needs work and we may want to offer it as optional.

Also adds logic to allow skipping margin adjustments in `._set_yrange()`
if you pass `range_margin=None`.

Tyler Goodlet 81f384db13 First draft, group y-minmax transform algo
On overlaid ohlc vizs we compute the largest max/min spread and
apply that maxmimum "up and down swing" proportion to each `Viz`'s
viewbox in the group.

We obviously still need to clip to the shortest x-range so that
it doesn't look exactly the same as before XD

Tyler Goodlet b15136a351 Rename `.maybe_downsample_graphics()` -> `.interact_graphics_cycle()` 2023-03-03 18:36:45 -05:00
Tyler Goodlet 1770ceeacc Right, handle y-ranging multiple paths per plot
We were hacking this before using the whole `ChartView._maxmin()`
setting stuff since in some cases you might want similarly ranged paths
on the same view, but of course you need to max/min them together..

This adds that group sorting by using a table of `dict[PlotItem,
tuple[float, float]` and taking the abs highest/lowest value for each
plot in the viz interaction update loop.

Also removes the now commented signal registry calls and thus
`._yranger`, drops the `set_range: bool` from `._set_yrange` and adds
and extra `.maybe_downsample_graphics()` to the mouse wheel handler to
avoid a weird slow debounce where ds-ing is delayed until a further
interaction.

Tyler Goodlet 399186a10a Drop Qt interaction signal usage
It's kind of hard to understand with the C++ fan-out to multiple views
(imo a cluster-f#$*&) and seems honestly just plain faster to loop (in
python) through all the linked view handlers XD

Core adjustments:
- make the panning and wheel-scroll handlers just call
  `.maybe_downsample_graphics()` directly; drop all signal emissions.
- make `.maybe_downsample_graphics()` loop through all vizs per subchart
  and use the new pipeline-style call sequence of:
  - `Viz.update_graphics() -> <read_slc>: tuple`
  - `Viz.maxmin(i_read_range=<read_slc>) -> yrange: tuple`
  - `Viz.plot.vb._set_yrange(yrange=yrange)`
  which inlines all the necessary calls in the most efficient way whilst
  leveraging `.maxmin()` caching and ymxmn-from-m4-during-render to
  boot.
- drop registering `._set_yrange()` for handling `.sigRangeChangedManually`.

Tyler Goodlet 5ce4337d42 Add first-draft `PlotItemOverlay.group_maxmin()`
Computes the maxmin values for each underlying plot's in-view range as
well as the max up/down swing (in percentage terms) from the plot with
most dispersion and returns a all these values plus a `dict` of plots to
their ranges as part of output.

Tyler Goodlet daa6a5c80a `ib`: restore and (maybe) use `xdotool` + `i3ipc` reset method
Since apparently the container we were using is totally borked on new
kernels and/or latest jvm, this move our old manual local-X-desktop script
back for use in `brokerd` backend code.

Adds a new `.brokers.ib._util` which contains the 2 methods and fails
over to this one when we can't connect to a VNC server. Also adjusts the
original in `scripts/ib_data_reset.py` to import and run the module code
as a script-program.

Tyler Goodlet 3a4794e9d1 Backward-compat: don't require `'lot_tick_size'`
In order to support existing `pps.toml` files in the wild which don't
have the `asset_type, price_tick_size, lot_tick_size` fields, we need to
only optionally read them and instead expect that backends will write
the fields going forward (coming in follow patches).

Further this makes some small asset-size (vlm accounting) quantization
related adjustments:
- rename `Symbol.decimal_quant()` -> `.quantize_size()` since that is
  explicitly what this method is doing.
- and expect an input `size: float` which we cast to decimal instead of
  doing it inside the `.calc_size()` caller code.
- drop `Symbol.iterfqsns()` which wasn't being used anywhere at all..

Additionally, this drafts out a new replacement market-trading-pair data
type to eventually replace `.data._source.Symbol` -> `MktPair` which we
aren't using yet, but serves as the documentation-driven motivator ;)
and, it relates to https://github.com/pikers/piker/issues/467.
