然而,mplot3d目前仅通过提供 3D-2D 投影提供(再次,仅)简单的 3D 绘图能力,并且基本上以 2D 进行所有绘图,这不是真正的 3D。 import numpy as np from numpy import * from matplotlib import pyplot as plt from mpl_toolkits.mplot3d import Axes3D from matplotlib.patches import FancyArrowPatch from mpl_...
与plot()类似,绘制柱状图的函数bar()和绘制直方统计图的函数hist()将创建一个Patch对象 的列表,每个元素实际上都是从Patch类派生的Rectangle对象,所创建的Patch对象都被添加进 了 Axes对象的patches属性中: fig, ax = pit.subplots() n, bins, rects = ax.hist(np.random.randn(1000), 50, facecolor="blue...
可以将它理解为一个单个画板, 一个Axes包含两个Axis(坐标轴)(在3D图中为三个Axis), 每个Axes都有 一个 title(方法: set_title()), 一个x-label(方法: set_xlabel()), 一个y-label(方法: set_ylabel()).注意:一个给出的Axes对象只能包含在一个Figure中。 Axis(坐标轴) 这是一种类似数轴的对象。可...
