首先绘图需要导入matplotlib.pyplot,其中pyplot是matplotlib的绘图框架,功能类似于于MATLAB的绘图功能,图形绘制需要利用到pyplot,即plt.plot()和plt.show(); 程序通过Numpy生成绘图所需数据,Numpy是Python的一个数据处理包,极大的方便了Python在科学计算方面的应用,在程序中通过使用Numpy内置linspace()生成区间在[-3,3]的...

In most cases, matplotlib will simply output the chart to your viewport when the.show()method is invoked, but we’ll briefly explore how to save a matplotlib creation to an actual file on disk. Using matplotlib While the feature-list of matplotlib is nearly limitless, we’ll quickly go ove...
