- added the `align` parameter to all topbar widgets, allowing for individual widgets to be placed either on the left or right hand side of the topbar.
- Disabled QtChart’s context menu by default.
Bug Fixes:
- The `screenshot` method now works for subcharts.
- Tables will still render if a `NoneType` is passed to them as a value.
- Qt and Wx charts no longer throw an error when using the toolbox.
- Added async methods to polygon.
- The `requests` library is no longer required, with `urllib` being used instead.
- Added the `get_bar_data` function, which returns a dataframe of aggregate data from polygon.
- Opened up the `subscribe` and `unsubscribe` functions
Enhancements:
- Tables will now scroll when the rows exceed table height.
Bugs:
- Fixed a bug preventing async functions being used with horizontal line event.
- Fixed a bug causing the legend to show duplicate lines if the line was created after the legend.
- Fixed a bug causing the line hide icon to persist within the legend after deletion (#75)
- Fixed a bug causing the search box to be unfocused when the chart is loaded.
Breaking Changes:
- Removed the `api` parameter; callbacks no longer need to be in a specific class.
- Topbar callbacks now take a chart as an argument (see updated callback examples)
- Removed the `topbar` parameter from chart declaration. The Topbar will be automatically created upon declaration of a topbar widget.
- Removed the `searchbox` parameter from charts. It will be created upon subscribing to it in `chart.events`.
- Removed `dynamic_loading`.
- Removed ‘volume_enabled’ parameter. Volume will be enabled if the volumn column is present in the dataframe.
- Widgets’ `func` parameter is now declared last.
- Switchers take a tuple of options rather than a variable number of arguments.
- `add_hotkey` renamed to `hotkey`
- Horizontal lines now take a `func` argument rather than `interactive`. This event will emit the Line object that was moved.
- Removed the `name` parameter from `line.set`. Line object names are now declared upon creation.
Enhancements:
- Added the `button` widget to the Topbar.
- Added the color picker to the drawing context menu.
- Charts now have a `candle_data` method, which returns the current data displayed on the chart as a DataFrame.
- Fixed callbacks are now located in the `chart.events` object:
- search (e.g `chart.events.search += on_search`)
- new_bar
- range_change
- Added volume to the legend
- Drawings can now be accessed through `chart.toolbox.drawings`
- added the `style` and `name` parameters to `create_line`
Bug Fixes:
- Fixed a bug causing new charts not to load after `exit` was called.
- Refactored rayline placement to ensure they do not move the visible range.
- Fixed a bug causing the visible range to shift when trendlines are moved past the final candlestick.
- Fixed a bug preventing trendlines and raylines on irregular timeframes.
- Fixed a bug causing the legend to prevent mouse input into the chart.
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.
