In operation and maintenance management, often encounter time series data, such as network card traffic, number of online users, number of concurrent connections, and so on. Scatter plots are used to visually visualize the distribution of data.The Pyplot of the Matplotlib module has a function of drawing a scatter plot, but the function requires that the x-axis be a numeric type. In the Pandas plot function

found that there is a non-ASCII code string If the encoding format of the source file on this basis is GBK, the compilation can be passed, but the printed string is garbled, why is it garbled? Because the IDE is using UTF-8 encoding format, and the source file is in the GBK format, so there will be garbled in Chinese, simple to solve garbled there are 3 possible ways, one way: the source files need to print the string decoded to Utf-8 (or Unicode) and then print Another method is to modify the

When we are dealing with a lot of data, we have to use the concept of time. such as timestamps, fixed periods, or time intervals. Pandas provides a standard set of time-series processing tools and data algorithms. The datetime.datetime module is the most used module in Python. Using datetime.datetime.now () , for example, gets the current time 2018-04-14 14:12:
