Tyler Goodlet 1add591b2c Only update last datum graphic(s) on clear ticks
When a new tick comes in but no new time step / bar is yet needed (to be
appended) we can simply adjust **only** the last bar datum
lines-graphic(s) to avoid a redraw of the preceding `QPainterPath` on
every tick. Do this by calling `Viz.draw_last()` on the fast and slow
chart and adjusting the guards around calls to `Viz.update_graphics()`
(which *does* update paths) to only enter when there's a `do_px_step`
condition. We can stop calling `main_viz.plot.vb._set_yrange()` on view
treading cases since the range should have already been adjusted by the
clearing-tick processing mxmn updates.

Further this changes,
- the `chart_maxmin()` helper (which we should eventually just get rid
  of) to take bound in `Viz`s for the ohlc and vlm chart instead of the
  chart widget handles.
- extend the guard around hist viz yranging to only enter when not in
  "axis mode" - the same as for the fast viz.

Tyler Goodlet 60440bc6b7 Ensure full hist OHLC path is drawn on tread
Since we removed the `Viz.update_graphics()` call from the main rt loop
we have to be sure to call it in the history chart incr-loop to avoid
a gap between the  last bar and prior history since startup. We only
need to update on tread since that should be the only time a full redraw
is ever necessary, ow only the last datum is needed.

Further this moves the graphics cycle func's profiler init to the top in
an effort to get more correct latency measures.

Tyler Goodlet 4003729231 Use `Viz.update_graphics()` throughout remainder of graphics loop where possible 2023-02-13 12:27:58 -05:00
Tyler Goodlet 934b32c342 Use `Viz` over charts where possible in display loop
Since `ChartPlotWidget.update_graphics_from_flow()` is more or less just
a call to `Viz.update_graphics()` try to call that directly where
possible.

Changes include:
- calling the viz in the display state specific `maxmin()`.
- passing a viz instance to each `ChartView._set_yrange()` call (in prep
  of explicit group auto-ranging); not that this input is unused in the
  method for now.
- drop `bars_range` var passing since we don't use it.

Tyler Goodlet 97bb3b48da Set a `PlotItem.viz` for interaction lookup
Inside `._interaction` routines we need access to `Viz` instances.
Instead of doing `CharPlotWidget._vizs: dict` lookups this ensures each
plot can lookup it's (parent) viz without error.

Also, adjusts `Viz.maxmin()` output parsing to new signature.

Tyler Goodlet bcf2a9868d Drop x-range query from `ChartPlotWidget.maxmin()`
Move the `Viz.datums_range()` call into `Viz.maxmin()` itself thus
minimizing the chart `.maxmin()` method to an ultra light wrapper around
the viz call. Also move all profiling into the `Viz` method.

Adjust `Viz.maxmin()` to return both the (rounded) x-range values which
correspond to the range containing the y-domain min and max so that
it can be used for up and coming overlay group maxmin calcs.

Tyler Goodlet 92ce1b3304 Only handle hist discrepancies when market is open
We obviously don't want to be debugging a sample-index issue if/when the
market for the asset is closed (since we'll be guaranteed to have
a mismatch, lul). Pass in the `feed_is_live: trio.Event` throughout the
backfilling routines to allow first checking for the live feed being active
so as to avoid breakpointing on false +ves. Also, add a detailed warning
log message for when *actually* investigating a mismatch.

Tyler Goodlet 5ced05aab0 Breakpoint bad (-ve or too large) x-ranges to m4
This should never really happen but when it does it appears to be a race
with writing startup pre-graphics-formatter array data where we get
`x_end` epoch value subtracting some really small offset value (like
`-/+0.5`) or the opposite where the `x_start` is epoch and `x_end` is
small.

This adds a warning msg and `breakpoint()` as well as guards around the
entire code downsampling code path so that when resumed the downsampling
cycle should just be skipped and avoid a crash.

Tyler Goodlet efa4089920 Attempt to keep selected item highlighted
This attempt was unsuccessful since trying to (re)select the last
highlighted item on both an "enter" or "click" of that item causes
a hang and then segfault in `Qt`; no clue why..

Adds a `keep_current_item_selected: bool` flag to
`CompleterView.show_cache_entries()` but using it seems to always cause
a hang and crash; we keep all potential use spots commented for now
obviously to avoid this. Also included is a bunch of tidying to logic
blocks in the kb-control loop for readability.

Tyler Goodlet 7afc9301ac Handle last-in-view time slicing edge case
Whenever the last datum is in view `slice_from_time()` need to always
spec the final array index (i.e. the len - 1 value we set as
`read_i_max`) to avoid a uniform-step arithmetic error where gaps in the
underlying time series causes an index that's too low to be returned.

Tyler Goodlet fe932a96a9 Make `PlotItemOverlay` add items inwards->out
Before this axes were being stacked from the outside in (for `'right'`
and 'bottom'` axes) which is somewhat non-intuitive for an `.append()`
operation. As such this change makes a symbol list stack a set of
`'right'` axes from left-to-right.

Details:
- rename `ComposeGridLayout.items` -> `.pitems`
- return `(int, list[AxisItem])` pairs from `.insert/append_plotitem()`
  and the down stream `PlotItemOverlay.add_plotitem()`.
- drop `PlotItemOverlay.overlays` and add it back as `@property` around
  the underlying `.layout.pitems`.

Factor and fix dst <- src pair parsing into a new func

a parsing bug for src asset balances which aren't only 3 chars long..
a terrible assumption.

Tyler Goodlet 42d3537516 Repair auto-y-ranging to always include L1 spread
Goes back to always adjusting the y-axis range to include the L1 spread
and clearing label in view whenever the last datum is also in view,
previously this was broken after reworking the display loop for
multi-feeds.

Drops a bunch of old commented tick looping cruft from before we started
using tick-type framing. Also adds more stringent guards for ignoring
but error logging quote values that are more then 25% out of range; it
seems particularly our `ib` feed has some issues with strange `price`
values that are way off here and there?

Tyler Goodlet b2bb7f4923 Simplify L1 labels for multicharts
Instead of having the l1 lines be inside the view space, move them to be
inside their respective axis (with only a 16 unit portion inside the
view) such that the clear price label can overlay with them nicely
without obscuring; this is much better suited to multiple adjacent
y-axes and in general is simpler and less noisy.

Further `L1Labels` + `LevelLabel` style tweaks:
- adjust `.rect` positioning to be "right" (i.e. inside the parent
  y-axis) with a slight 16 unit shift toward the viewbox (using the new
  `._x_br_offset`) to allow seeing each level label's line even when the
  clearing price label is positioned at that same level.
- add a newline's worth of vertical space to each of the bid/ask labels
  so that L1 labels' text content isn't ever obscured by the clear price
  label.
- set a low (10) z-value to ensure l1 labels are always placed
  underneath the clear price label.
- always fill the label rect with the chosen background color.
- make labels fully opaque so as to always make them hide the parent
  axes' `.tickStrings()` contents.
- make default color the "default" from the global scheme.
- drop the "price" part from the l1 label text contents, just show the
  book-queue's amount (in dst asset's units, aka the potential clearing vlm).
