downtrend): it can be clearly found that, if the band trader as a medium-term, It is much better to use the logarithmic coordinate trend line to judge the trend end and the reverse pumping position than to use the normal coordinates in time. The principle of common coordinates and logarithmic coordinates shows that the difference between common and logarithmic coordinates in short period is very small, but the common coordinate and logarithmic coordinate may differ greatly in the long period, s

Matplotlib's official website address: http://matplotlib.org/ When using Python to do data processing, a lot of the data we don't seem to be intuitive, and sometimes it's graphically shown that it's easier to observe the changing characteristics of the data, and so on. Matplotlib is a Python 2D drawing library that generates publishing quality-level graphics in a variety of hard copy formats and cross-platf

Introduced Matplotlib is Python's most famous drawing library, which provides a complete set of command APIs similar to MATLAB and is ideal for interactive charting. It can also be conveniently embedded in GUI applications as a drawing control. Its documentation is fairly complete, and there are hundreds of thumbnails on the Gallery page, which are available after they are opened. So if you need to draw some kind of diagram, just browse/copy/paste it in this page, and basically you can do it.
