Tables Feature
- Added the `create_table` method, which returns a `Table` object. This can be used to display watchlists, order windows, position windows and more.
- See the new page on the docs for more information!
Bugs
- Fixed a bug preventing the named column of a line to not work as a label of the series.
- Fixed a bug causing drawings loaded from the minute timeframe to not show on a daily timeframe.
- Fixed a bug causing `chart.exit` to not work.
- Fixed a bug preventing the chart from being moved after placing a ray.
- Fixed the ‘price in hoveringOver’ web console error.
Enhancements
- The date/time column can also be the `name` of the passed series object.
- Added the `label` method to `HorizontalLine`, allowing for the price line label of horizontal lines to be updated.
- `None` or an empty DataFrame can now be passed to `line.set` as a means to clear it.
- Seperate Chart objects will now run on the same pywebview instance. This means that any Chart objects created after the first will inherit the first Chart’s API.
- Reorganized the documentation for clarity.
NEW FEATURE: Polygon.io Full integration
- Added `polygon` to the common methods, allowing for data to be pulled from polygon.io. (`chart.polygon.<method>`)
- Added the `PolygonChart` object, which allows for a plug and play solution with the Polygon API.
- Check the docs for more details and examples!
Enhancements:
- Added `clear_markers` and `clear_horizontal_lines` to the common methods.
- Added the `maximize` parameter to the `Chart` object, which maximizes the chart window when shown.
- The Legend will now show Line values, and can be disabled using the `lines` parameter.
- Added the `name` parameter to the `set` method of line, using the column within the dataframe as the value and using its name within the legend.
- Added the `scale_candles_only` parameter to all Chart objects, which prevents the autoscaling of Lines.
- new `screenshot` method, which returns a bytes object of the displayed chart.
Fixes:
- `chart.lines()` now returns a copy of the list rather than the original.
- 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.
- 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.
