matplotlib of common classes in the Figure -> Axes-> (line2d, Text, etc.). A figure object can contain multiple child graphs (Axes), and a Axes object represents a plot area in Matplotlib, which can be understood as a child graph. You can use subplot () to quickly draw a chart that contains multiple child graphs, which are called as follows: subplot (NumRows, Numcols, plotnum) subplot divides the entire drawing area into numrows rows * numc

It is also necessary to register that we also have a cross join of "cross-set", which is not represented by Wenshitu because it is a n*m combination of the data of table A and table B, that is, the Cartesian product. The expression is as follows: 1 SELECT* FROMTableA 2 CROSSJOINTableB This Cartesian product produces 4 x 4 = 16 records, which, in general, are seldom used in this syntax
