我想画一张Minkowski图。 它包括两个不同的轴,每个系统一个,但它们不是全部正交的。有没有办法为一个非正交的系统绘制一对轴?

以下是使用AxisArtist和GridHelperCurveLinear的示例,该示例已从here修改。
import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.axisartist.grid_helper_curvelinear import GridHelperCurveLinear
from mpl_toolkits.axisartist import Subplot
def curvelinear_test1(fig):
def tr(x, y):
x, y = np.asarray(x), np.asarray(y)
return .8*x+.2*y, .2*x + .8*y
def inv_tr(x,y):
x, y = np.asarray(x), np.asarray(y)
return 1.333*x + -.333*y, -.333*x + 1.333*y
grid_helper = GridHelperCurveLinear((tr, inv_tr))
ax1 = Subplot(fig, 1, 1, 1, grid_helper=grid_helper)
fig.add_subplot(ax1)
xx, yy = tr([3, 6], [5.0, 10.])
ax1.plot(xx, yy)
ax1.set_aspect(1.)
ax1.set_xlim(-10, 10.)
ax1.set_ylim(-10, 10.)
ax1.axis["t"]=ax1.new_floating_axis(0, 0.)
ax1.axis["t2"]=ax1.new_floating_axis(1, 0.)
ax1.grid(True)
fig = plt.figure()
curvelinear_test1(fig)
plt.show()
