matplot三维图

方式一：Axes3D绘制三维图

from mpl_toolkits.mplot3d import Axes3D

def Plot3D(data):
    x, y, z = data[0], data[1], data[2]
    fig = plt.figure()  # 创建一个三维的绘图工程

    ax = Axes3D(fig)

    ax.set_zlabel('Z')  # 坐标轴
    ax.set_ylabel('Y')
    ax.set_xlabel('X')

    cx = np.mean(x)
    cy = np.mean(y)
    cz = np.mean(z)
    
　　#设置坐标范围
    delta = 1000
    ax.set_xlim(cx-delta, cx+delta)
    ax.set_ylim(cy-delta, cy+delta)
    ax.set_zlim(cz-delta, cz+delta)

    ax.scatter3D(x,y,z)
    plt.show()
