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.
- Removed bar data from exported drawings, which should reduce the file size of exported drawings. (Make sure to back up any drawing files before running the new version!)
- Drawings can now be deleted through each’s right click context menu.
- Added the new ‘hotkey’ method, which will execute the given method or function when the key command is pressed.
- Non-fixed callbacks no longer need to be placed in the API class.
- Added `toolbox` to the common methods.
- `toolbox.save_drawings_under` can save drawings under a specific `topbar` widget. eg `chart.toolbox.save_drawings_under(chart.topbar[’symbol’]`)
- `toolbox.load_drawings` will load and display drawings stored under the tag/string given.
- `toolbox.export_drawings` will export all currently saved drawings to the given file path.
- `toolbox.import_drawings` will import the drawings stored at the given file path.
Fixes/Enhancements:
- `update` methods are no longer case sensitive.
- HorizontalLines no longer throw cyclic structure errors in the web console.
- `API` methods can now be normal methods or coroutines.
- Added `trend_line` and `ray_line` to the Common Methods.
- Added the `toolbox` parameter to chart declaration. This allows horizontal lines, trend lines and rays to be drawn on the chart using hotkeys and buttons.
- cmd-Z will delete the last drawing.
- Drawings can be moved by clicking and dragging.
- Added the `render_drawings` parameter to `set`, which will keep and re-render the drawings displayed on the chart (useful for multiple timeframes!)
Horizontal Lines
- The `horizontal_line` method now returns a HorizontalLine object, containing the methods `update` and `delete`.
- Added the `interactive` parameter to `horizontal_line`, allowing for callbacks to be emitted to the `on_horizontal_line_move` callback method when the line is dragged to a new price (stop losses, limit orders, etc.).
Enhancements:
- added the `precision` method to the Common Methods, allowing for the number of decimal places shown on the price scale to be declared.
- Lines displayed on legends now have toggle switches, allowing for their visibility to be controlled directly within the chart window.
- when using `set`, the column names can now be capitalised, and the `date` column can be the index.
Changes:
- Merged the `title` method into the `price_line` method.
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.
