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 very powerful Python module for drawing two-dimensional graphics, it uses the Python language to achieve the ease of use of MATLAB drawing functions, but also has a very strong customizable. It provides a complete set of command APIs similar to those of MATLAB and is ideal for interactive mapping. It ca

When using matplotlib drawing to add a formula to a picture, it is generally necessary to use the text or annotate function, combined with latex grammar ' $...$ '.For fractions, if you use \frac{}{} directly, the characters on the numerator denominator are small, as shown in the Green formula.To solve this problem, we need to use the \displaystyle, that is, using the ' $\displaystyle ... $ ', as shown in the Blue formula in the effect. However, the pr
