Changes for 0.63
================
.. code-block:: text
Dates are now represented internally as float days since 0001-01-01,
UTC.
All date tickers and formatters are now in matplotlib.dates, rather
than matplotlib.tickers
converters have been abolished from all functions and classes.
num2date and date2num are now the converter functions for all date
plots
Most of the date tick locators have a different meaning in their
constructors. In the prior implementation, the first argument was a
base and multiples of the base were ticked. e.g.,
HourLocator(5) # old: tick every 5 minutes
In the new implementation, the explicit points you want to tick are
provided as a number or sequence
HourLocator(range(0,5,61)) # new: tick every 5 minutes
This gives much greater flexibility. I have tried to make the
default constructors (no args) behave similarly, where possible.
Note that YearLocator still works under the base/multiple scheme.
The difference between the YearLocator and the other locators is
that years are not recurrent.
Financial functions:
matplotlib.finance.quotes_historical_yahoo(ticker, date1, date2)
date1, date2 are now datetime instances. Return value is a list
of quotes where the quote time is a float - days since gregorian
start, as returned by date2num
See examples/finance_demo.py for example usage of new API
