chart context as parameter

4

Hello, how would you extract the following code into its own function? ```rust chart .draw_series(LineSeries::new( (-100..100) .map(|y| y as f64 / 40.0) .map(|y| ((y * 10.0).sin(), y, (y * 10.0).cos())),...

`parse_date_string` accepts invalid time clue: example: ```rust parse_date_string("10am hello world", Local::now(), Dialect::Uk).is_ok(); // evaluates to true ```

Currently there is no file locking. Running several `rtw` commands may lead to undefined behavior.
