Tyler Goodlet d170132eb5 Use view for auto-yrange in display loop 2022-01-25 07:59:08 -05:00
Tyler Goodlet ced310c194 Add `ChartPlotWidget.maxmin()` to calc in-view hi/lo y-values
As part of factoring `._set_yrange()` into the lower level view box,
move the y-range calculations into a new method. These calcs should
eventually be completely separate (as they are for the real-time version
in the graphics display update loop) and likely part of some kind of
graphics-related lower level management API. Draft such an API as an
`ArrayScene` (commented for now) as a sketch toward factoring array
tracking **out of** the chart widget. Drop the `'ohlc'` array name and
instead always use whatever `.name` was assigned to the chart widget
to lookup its "main" / source data array for now.

Enable auto-yranging on overlayed plotitems by enabling on its viewbox
and, for now, assign an ad-hoc `._maxmin()` since the widget version
from this commit has no easy way to know which internal array to use. If
an FSP (`dolla_vlm` in this case) is overlayed on an existing chart
without also having a full widget (which it doesn't in this case since
we're using an overlayed `PlotItem` instead of a full `ChartPlotWidget`)
we need some way to define the `.maxmin()` for the overlayed
data/graphics. This likely means the `.maxmin()` will eventually get
factored into wtv lowlevel `ArrayScene` API mentioned above.

Tyler Goodlet 80d16886cb Add auto-yrange handler to our `ChartView`
Calculations for auto-yaxis ranging are both signalled and drawn by our
`ViewBox` so we might as well factor this handler down from the chart
widget into the view type. This makes it much easier (and clearer) that
`PlotItem` and other lower level overlayed `GraphicsObject`s can utilize
*size-to-data* style view modes easily without widget-level coupling.

Further changes,
- support a `._maxmin()` internal callable (temporarily) for allowing
  a viewed graphics object to define it's own y-range max/min calc.
- add `._static_range` var (though usage hasn't been moved from the
  chart plot widget yet
- drop y-axis click-drag zoom instead reverting back to default viewbox
  behaviour with wheel-zoom and click-drag-pan on the axis.

Tyler Goodlet 4b89f7197a Move multi-view overlay components in from `pyqtgraph` PR
This brings in the WIP components developed as part of
https://github.com/pyqtgraph/pyqtgraph/pull/2162.

Most of the history can be understood from that issue and effort but the
TL;DR is,

- add an event handler wrapper system which can be used to
  wrap `ViewBox` methods such that multiple views can be overlayed and
  a single event stream broadcast from one "main" view to others which
  are overlaid with it.
- add in 2 relay `Signal` attrs to our `ViewBox` subtype (`Chartview`)
  to accomplish per event `MouseEvent.emit()` style broadcasting to
  multiple (sub-)views.
- Add a `PlotItemOverlay` api which does all the work of overlaying the
  actual chart graphics and arranging multiple-axes without collision as
  well as tying together all the event/signalling so that only a single
  "focussed" view relays to all overlays.

Tyler Goodlet 637c9c65e9 Drop old grid-based overlay cruft 2022-01-25 07:59:08 -05:00
Tyler Goodlet 12e04d57f8 Add a "composed" layout for arbitrary multi-axes
Each `pyqtgraph.PlotItem` uses a `QGraphicsGridLayout` to place its view
box, axes and titles in the traditional graph format. With multiple
overlayed charts we need those axes to not collide with one another and
further allow for an "order" specified by the user. We accomplish this
by adding `QGraphicsLinearLayout`s for each axis "side": `{'left',
'right', 'top', 'bottom'}` such that plot axes can be inserted and moved
easily without having to constantly re-stack/order a grid layout (which
does not have a linked-list style API).

The new type is called `ComposedGridLayout` for now and offers a basic
list-like API with `.insert()`, `.append()`, and eventually a dict-style
`.pop()`. We probably want to also eventually offer a `.focus()` to
allow user switching of *which* main graphics object (aka chart) is "in
use".

Tyler Goodlet 9e18afe0d7 WIP `PlotItemOverlay` support to get multi-yaxes
This syncs with a dev branch in our `pyqtgraph` fork:
https://github.com/pyqtgraph/pyqtgraph/pull/2162

The main idea is to get mult-yaxis display fully functional with
multiple view boxes running in a "relay mode" where some focussed view
relays signals to overlaid views which may have independent axes. This
preps us for both displaying independent codomain-set FSP output as well
as so called "aggregate" feeds of multiple fins underlyings on the same
chart (eg. options and futures over top of ETFs and underlying stocks).
The eventual desired UX is to support fast switching of instruments for
order mode trading without requiring entirely separate charts as well as
simple real-time anal of associated instruments.

The first effort here is to display vlm and $_vlm alongside each other
as a built-in FSP subchart.

Tyler Goodlet 9c57f10e77 Make pause/resume feed methods sync again
We can instead use the god widget's nursery to schedule all the feed
pause/resume requests and be even more concurrent during a view (of
symbols) switch.

Use `tractor.trionics.gather_contexts()` to start up the fsp and volume
chart-displays (for an additional conc speedup). Drop `dolla_vlm` again for
now until we figure out how we can display it *and* vlm on the same
sub-chart? It would be nice to avoid having to spawn an fsp process
before showing the volume curve.

Tyler Goodlet 56b65a1cde Make chart switching super fast again
This fixes a weird re-render bug/slowdown/artifact that was introduced
with the order mode sidepane work. Prior to the sidepane addition, chart
switching was immediate with zero noticeable widget rendering steps.

The slow down was caused by 2 things:
- not yielding back to the Qt loop asap after re-showing/focussing
  a linked split chart that was already in memory.
- pausing/resuming feeds only after a Qt loop render cycle has
  completed.

This now restores the near zero latency UX.

Tyler Goodlet 9951e1d4c9 Fix shm index update race
There was a lingering issue where the fsp daemon would sync its shm
array with the source data and we'd set the start/end indices to the
same value. Under some races a reader would then read an empty `.array`
which it wasn't expecting. This fixes that as well as tidies up the
`ShmArray.push()` logic and adds a temporary check in `.array` for zero
length if the array hasn't been written yet.

We can now start removing read array length checks in consumer code
and hopefully no more races will show up.
