Version notes

Versión (1.2.3) - Modification date: 17/ABR/2019
Support for terminals that by default have the environment variable LD_LIBRARY_PATH blank and can not be installed correctly numpy, scipy and matplotlib.

Versión (1.2.2) - Modification date: 17/ABR/2019
Support for new version of termux, addition of library "zlib-dev" for correct compilation of matplotlib

Version (1.2.1) - Modification date: 16/MAR/2019
The modification was added to run the latest version of matplotlib (3.0.3)
Major improvement!:
The matplotlib 3.0.3 version will automatically detect the backend "Agg", this is explained as follows,:

Old import:

import matplotlib
matplotlib.use ("Agg")
import matplotlib.pyplot as a plot

The previous code can be simplified by (giving the same result):

import matplotlib.pyplot as a plot

Important : This did NOT provide graphics availability by using plot.show() , to save the graphics it is recommended to use plot.savefig(file_name).

Version (1.2.0) - Modification date: 18/NOV/2018
Modification was added to run the latest version of matplotlib (3.0.2)
