- 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.

ToolBox
The Toolbox allows for trendlines, ray lines and horizontal lines to be drawn and edited directly on the chart.
It can be used within any Chart object, and is enabled by setting the `toolbox` parameter to `True` upon Chart declaration.
The following hotkeys can also be used when the Toolbox is enabled:
| Key Cmd | Action |
|--- |--- |
| `alt T` | Trendline |
| `alt H` | Horizontal Line |
| `alt R` | Ray Line |
| `⌘ Z` or `ctrl Z` | Undo |
Right-clicking on a drawing will open a context menu, allowing for color selection and deletion.
