Matplotlib 里的常用类的包含关系为Figure -> Axes -> (Line2D, Text, etc.)一个Figure对象可以包含多个子图(Axes),在matplotlib中用Axes对象表示一个绘图区域,可以理解为子图。 可以使用subplot()快速绘制包含多个子图的图表,它的调用形式如下: subplot(numRows, numCols, plotNum) subplot将整个绘图区域等分为num...
Using custom fonts adds a nice touch to your graph and make it shine among all the other plots using defaults. Thesimplest wayto customize your fonts is with thePyFontslibrary, which lets youload any font from the webwith just a single line of code!

We do this explicitly, and this in turn allows for a greater level of control and customization when constructing our figures. The following code snippet demonstrates how to plot a line graph using the object-oriented interface: filter_none import matplotlib.pyplot as plt # Initialize a Figure...
