Lightweight-charts

Bugs

* Fix chart crash when clicking outside of the visible range (406, 405, 454)
* Ensure Two point drawings have a logical value (420)
* Scrollable Legend (399)
* Fix legend color bug (424)
* Fix settings items, default value on topbar menu (442, 404)

Enhancements
* Add `price_scale_id` parameter to lines (408)

* Prevent textboxes and search boxes from clashing
* Fix legend item deletion bug
* Fix legend throwing error bug
* Update docs to reflect that `remove_horizontal_line` and `clear_horizontal_lines` are no longer methods

This version introduces breaking changes:
* `render_drawings` has been replaced with `keep_drawings`
* removed the `block` parameter from `show_async`. use `asyncio.create_task` instead.
* added toggle parameter to topbar buttons; buttons value now reflects their state

Main changes:
* Entire rewrite of the backend in TypeScript; drawings should be more reliable and stable now.
* Plugin support (Box drawing). Please feel free to implement your own plugins!
* Added support for PyQt6 (with plans to drop support for Qt5 and PySide)
* Editable text boxes
* Added the `bulk_run` context manager, which can be used to send a group of commands to the chart. for example:

python
with chart.bulk_run:
for i in range(300):
chart.horizontal_line(i)

this code would execute much faster within the context manager as each method’s piece of JavaScript is grouped into one.

There are likely to be some discrepancies in the documentation at the moment; if you find any please raise an issue!

Thank you to everyone who has helped build this library, my sponsors, and the users!
