Candlestick OCHL graph

问题:

I am trying to import matplotlib.finance module in python. My matplotlib.pyplot version is 2.00. When I import using the following commands

import matplotlib.finance from matplotlib.finance import candlestick_ohlc 

I get an error "warnings.warn(message, mplDeprecation, stacklevel=1) MatplotlibDeprecationWarning: The finance module has been deprecated in mpl 2.0 and will be removed in mpl 2.2. Please use the module mpl_finance instead."

Then instead of using the above lines in python if I use the following line

import mpl_finance 

I get an error "ImportError: No module named 'mpl_finance'". What should I do to import candlestick from matplotlib.pyplot?

What this warning tells you is that the finance module will be removed at some point.

At the moment you don't need to worry about this warning. It will only affect you, when you update to a yet to be released version 2.2 of matplotlib, in which case you'll need to change your imports.

If you already want to be compatible with future versions now, you can download the mpl_finance module from https://github.com/matplotlib/mpl_finance .

After having downloaded the files, you may install in the usual way,

python setup.py install 

Alternatively you may try installing through pip,

pip install mpl_finance 

The reason for this is that the people at matplotlib want to keep their code clean and not maintain a specialized sidepackage like this in the main code. They probably also do not want to maintain the package and spend resources on it, which can be better used in the core developpment.

Since mpl_finace is not on pip now, you may also want to use following command to install mpl_finance by pip:

pip install https://github.com/matplotlib/mpl_finance/archive/master.zip
