A wave of graph-based approaches to data science and machine learning is rising. We live in an era where theopens in new tabexponential growth of graph technology is predicted[1]. The ability to analyze data points through the context of their relationships enables more profound and accurate ...
plt.plot(df['Mes'], df['data science'], label='data science') #The parameter label is to indicate the legend. This doesn't mean that it will be shown, we'll have to use another command that I'll explain later. 我们可以在同一张图中制作多个变量的图,然后进行比较。 plt.plot(df ['...
