v1.0.16: Refactoring/Enhancements/Fixes

Refactoring/Enhancements/Fixes

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. (#52)
• 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.
• Legend will now follow the precision of the chart (#65)
• Drawings can now be accessed through chart.toolbox.drawings
• added the style and name parameters to create_line (#68)
• Added support for PySide6 (#62)

Bug Fixes:

• Fixed a bug causing new charts not to load after exit was called. (#60)
• Refactored rayline placement to ensure they do not move the visible range. (#64)
• 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. (#66)
• Fixed a bug causing the legend to prevent mouse input into the chart.

v1.0.15: Enhancements and Bug Fixes

• 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. (#51)
• 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.

v1.0.14.4: Fixes/Enhancements

Fixes/Enhancements

• 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.

• 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.
