示例1: uniform
# 需要导入模块: from Stoner import Data [as 别名]
# 或者: from Stoner.Data import plot_xyz [as 别名]
# Create some points approximately spherical distribution
p = uniform(low=-pi / 2, high=pi / 2, size=250)
q = uniform(low=-pi, high=pi, size=250)
r = normal(loc=3.0, size=250, scale=0.5)
x, y, z = transform(r, q, p)
x += 3.0
y -= 4.0
z += 2.0
# Construct the DataFile object
d = Data(column_stack((x, y, z)), setas="xyz", filename="Best fit sphere")
d.template.fig_width = 5.2
d.template.fig_height = 5.0 # Square aspect ratio
d.plot_xyz(plotter="scatter")
# curve_fit does the hard work
popt, pcov = d.curve_fit(sphere, (0, 1, 2), zeros_like(d.x))
# This manually constructs the best fit sphere
a, b, c, r = popt
p = linspace(-pi / 2, pi / 2, 16)
q = linspace(-pi, pi, 31)
P, Q = meshgrid(p, q)
R = ones_like(P) * r
x, y, z = transform(R, Q, P)
x += a
y += b
z += c
示例2: plane
# 需要导入模块: from Stoner import Data [as 别名]
# 或者: from Stoner.Data import plot_xyz [as 别名]
def plane(coord, a, b, c):
"""Function to define a plane"""
return c - (coord[0] * a + coord[1] * b)
coeefs = [1, -0.5, -1]
col = linspace(-10, 10, 6)
X, Y = meshgrid(col, col)
Z = plane((X, Y), *coeefs) + normal(size=X.shape, scale=7.0)
d = Data(
column_stack((X.ravel(), Y.ravel(), Z.ravel())),

setas="xyz",
)
d.column_headers = ["X", "Y", "Z"]
d.figure(projection="3d")
d.plot_xyz(plotter="scatter")
popt, pcov = d.curve_fit(plane, [0, 1], 2, result=True)
d.setas = "xy.z"
d.plot_xyz(linewidth=0, cmap=cmap.jet)
txt = "$z=c-ax+by$\n"
txt += "\n".join([d.format("plane:{}".format(k), latex=True) for k in ["a", "b", "c"]])
ax = plt.gca(projection="3d")
ax.text(15, 5, -50, txt)
d.draw()
