Pandas Series.keys() function is an alias for index. You can easily create NaN values in Pandas DataFrame by using Numpy. There is an additional argument that you can play with — na_action, which specifies how the mapping deals with the NaN value of the exiting Series. for pandas DataFrame, say 'df', how can i plot speed over meters with type as the key of marker dictionary.
