要使用Matplotlib，首先需要安装matplotlib库：pip install matplotlib==3.2.0 -i https://pypi.douban....
Normally when you create a Matplotlib Chart/Graph it is displayed in a small window. But what happens when you want to create multiple plots in matplotlib? Creating multiple windows with one graph each is not the solution as it would greatly clutter the screen. ...
Hidden in the matplotlib docs is this helpful snippet: “[With pyplot], simple functions are used to add plot elements (lines, images, text, etc.) to the current axes in the current figure.” [emphasis added] Hardcore ex-MATLAB users may choose to word this by saying something like, “...
在上述代码中,我们首先使用sns.set()函数设置Seaborn的样式为白色网格风格。然后使用sns.lineplot()函数绘制历史价格和预测价格曲线,这种方式比直接使用Matplotlib更加简洁。 2. 绘制价格分布直方图(Seaborn) 除了价格趋势曲线,我们还可以绘制价格分布直方图,以了解价格的分布情况。
