在多变量数据分析中，涉及三个变量的数据可视化往往需要采用三维绘图技术，以便更全面地理解和分析在二维表示中难以清晰呈现的复杂关系和数据模式。 Python 的 Matplotlib 库通过其 mpl_toolkits.mplot3d 工具包，为复杂三维可视化的生成提供了强大的功能支持。

很多情况下，为了能够观察到数据之间的内部的关系，可以使用绘图来更好的显示规律。 比如在下面的几张动图中，使用matplotlib中的三维显示命令，使得我们可以对于logistic回归网络的性能与相关参数有了更好的理解。 下面的动图显示了在训练网络时，不同的 ...

Sometimes I have to write stuff so I won't forget how to do it. This is one of those times. In my recent post on the angular size of a soccer goal, I created a contour plot. Despite what you might ...
