matplotlib--Configuration Parameters

Matplotlib is an Open-source project initiated by John Hunter. There is a little story about the origin of Matplotlib. John Hunter and his colleagues who studied epilepsy were using a proprietary software to analyze the EEG, but his lab had only one license for the analysis software. He and many of the colleagues working together had to take turns using the software's hardware to encrypt the dog. Johnhunter then has the idea of developing a tool to replace the software currently in use. At that time, MATLAB is widely used in the biomedical industry, John Hunter and so on originally want to develop a version based on MATLAB, but due to some limitations and shortcomings of MATLAB, coupled with his own python very familiar with, so there is the birth of matplotlib. Therefore, whether from the name, or from the matplotlib provided by the function name, parameters and use methods are very similar to MATLAB.

MATPLOTLIBRC is a configuration file with matplotlib default parameter settings in the file.

Import matplotlib
