线段简化(line segment simplification) 对于包含线段的图像(例如,经典的折线图、多边形的轮廓等),可以通过变量rcParams["path.simplify"](默认值:True)以及rcParams["path.simplify_threshold"](默认值:1/9)来控制图像的渲染时间。rcParams["path.simplify"]是个布尔变量,用于控制是否启用线段简化功能。rcParams["path...

matplotlib.pyplot模块:位于matplotlib的顶层,它是一个state-machine environment。该模块中的很多函数是用于给当前Figure的当前Axes添加plot element,比如line、text、image等。它非常类似于Matlab的用法。 下一层是面向对象的接口:在这一层pyplot只是用部分函数来创建Figure,然后通过该Figure显式的创建Axes,然后通过面向对象...
