- Removed ChartAsync.
- Added the `show_async` method to `Chart`.
- Refactored how the TopBar is used. The docs explain this in detail, but a basic rundown is:
- `corner_text` and `create_switcher` are no longer methods. The `topbar` attribute of `chart` should be used instead.
- switchers and textboxes, now created with `chart.topbar.textbox` and `chart.topbar.switcher` require a name to be passed to them, which is used to access its instance (e.g `chart.topbar[‘timeframe’]`)
- If you have any questions about these changes, or potential enhancements, feel free to raise an issue and I will get back to you ASAP :)
- PtQt and Wx can now use either synchronous or asynchronous callback functions
- BETA: Support for Jupyter Notebooks
- Fixed a bug causing the ‘date’ column of DataFrames passed to `set`, `update`, and `update_from_tick` to be modified.
- Added the ChartAsync class, allowing for more sophisticated Charts and SubCharts.
- Symbol searching, timeframe selectors, and more is now possible with this varation of Chart.
`QtChart` and `WxChart` have access to all the methods that `ChartAsync` has, however they utilize their own respective event loops rather than asyncio.
New Feature: `StreamlitChart`
- Chart window that can display static data within a Streamlit application.
Removed the `subscribe_click` method.
- BETA: Dynamic candlestick loading
- the config method has been removed, and its methods can now be found in various places:
- right_padding: moved to the ‘time_scale’ method.
- mode: moved to the ‘price_scale’ method.
- title: declared in the new ‘title’ method.
- It is now possible to update titles, horizontal_lines, and markers within Line objects.
- Upgraded to Lightweight Charts v4.0.1.
- Added a ‘hover’ item to the returning dictionary from subscribe_click.
- Markers and SubCharts no longer use a UUID for identification, but an 8 character string.
- Added the create_subchart method to Chart.
- Added the SubChart class.
- Added an inner_width and inner_height parameter to Chart.
- The time_scale method can now disable the time scale completely.
Bugs:
- Fixed a bug which prevented markers from being placed on charts with a timescale less than a day.
