- 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.
