show() Scikit-Learn 中包含的 digits 数据集中一些手写数字的有趣可视化效果;该数据集由近 2,000 8 \times 8的缩略图组成,显示了各种手写数字。我们先展示这些手写数字,然后展示其二维降维后的散点图,用离散色图进行标识。 # load images of the digits 0 through 5 and visualize several of them from sk...

plt.show() 利用subplot_adjust()函数可以对画的多个子图进行调整,它一共有left、right, bottom, top, wspace, hspase 六个参数,取 值从0至1。 对于上面的很多很多对象,其实都是Artist对象,Artist对象共分为简单类型和容器类型两种哦。简单的类型是标准的绘图元件,如:line2D, Rectangle, Text, AxesImage等。而...

The main purpose of plt.show(), as the name implies, is to actually “show” (open) the figure when you’re running with interactive mode turned off. In other words:If interactive mode is on, you don’t need plt.show(), and images will automatically pop-up and be updated as you ...
