Type errors
After running grep -Ern "type: ?ignore" pandas/ in the terminal, there's a list of type errors. I fixed type errors in three files:
- plotting/_matplotlib/timeseries.py
- core/methods/to_dict.py
- plotting/_matplotlib/converter.py
Thanks for the pull request, but it appears to have gone stale. If interested in continuing, please merge in the main branch, address any review comments and/or failing tests, and we can reopen.
