创建Axes3D主要有两种方式,一种是利用关键字projection='3d'l来实现,另一种则是通过从mpl_toolkits.mplot3d导入对象Axes3D来实现,目的都是生成具有三维格式的对象Axes3D. #方法一,利用关键字 from matplotlib import pyplot as plt from mpl_toolkits.mplot3d import Axes3D #定义坐标轴 fig = plt.figure() ax...
绘制曲面图使用的是plot_surface()方法,这个方法的参数相对而言更简单。且X、Y、Z三者的顺序相对较为容易分辨。 通过读示例代码,即可快速掌握其用法: import matplotlib.pyplot as plt import numpy as np from mpl_toolkits.mplot3d import Axes3D plt.rcParams['font.sans-serif'] = ['STKAITI'] plt.r...

使用matplotlib进行三维可视化需要使用其3D绘图功能,即mpl_toolkits.mplot3d。下面是一个简单的例子,展示如何使用matplotlib进行三维数据的可视化:```pythonimport matplotlib.pyplot as pltimport numpy as npfrom mpl_toolkits.mplot3d import Axes3D# 生成数据x = np.random.standard_normal(100)y = np.random....
figure() ax = Axes3D(fig) ax.plot_surface(X, Y, Z, rstride=1, cstride=1, cmap='summer') ax.set_xlabel('x') ax.set_ylabel('y') ax.set_zlabel('z') ax.set_zlim(-1.5,1.5) plt.show() 本期的介绍就到这里了,文中代码可以横向滑动浏览,为方便实操,相关的代码和样例存已存放至...
