purpose. Is there a way you can gather the output html and upload them

All,
If I am using this in my conf.py in Sphinx:
extensions = ['matplotlib.sphinxext.mathmpl',
'matplotlib.sphinxext.only_directives',
'matplotlib.sphinxext.plot_directive']
Is there a way I can use ams-latex constructs such as:
\begin{align*}
x+2y&=3\\
2x-3y&=4
\end{align*}
D.
All, I have:
from mpl_toolkits.mplot3d import axes3d
import matplotlib.pyplot as plt
import numpy as np
fig=plt.figure()
ax=axes3d.Axes3D(fig)
x=np.linspace(-2,2,40)
y=np.linspace(-2,2,40)
X, Y=np.meshgrid(x,y)
Z=6-2*X**2
ax.plot_wireframe(X,Y,Z)
ax.set_xlabel('x-axis')
ax.set_ylabel('y-axis')
All,
Is there any way to rotate a 3D plot_wireframe?

I tried using sphinx.ext.pngmath. See:

Hi,
I'm trying to get manual labeling of contours to work:
import numpy as np
import matplotlib.mlab as mlab
import matplotlib.pyplot as plt
delta = 0.025
x = np.arange(-3.0, 3.0, delta)
y = np.arange(-2.0, 2.0, delta)
X, Y = np.meshgrid(x, y)
Z1 = mlab.bivariate_normal(X, Y, 1.0, 1.0, 0.0, 0.0)
All,
I am still wondering why there is no comet command in matplotlib.
I was successful with the following:
import matplotlib.pyplot as plt
import numpy as np
len=200
t=np.linspace(0,2*np.pi,len)
x=np.cos(t)
y=np.sin(t)
xd=[x[0]]
yd=[y[0]]
l,=plt.plot(xd,yd)
plt.axis([-1,1,-1,1])
for i in np.
pace(0,2*pi,2000);
x=-sin(t);
y=cos(t);
plot(x,y)
Because the student just sees sees the "finished" path. The comet command, on
the other hand, allows the student to "see" that path as it is traced out in
real time.

I still feel that a comet routine should be added to matplotlib for the reasons
I've delineated.

Does Matplotlib have a form of the clabel command that uses the

[c,h]=contour(x,y,z);
clabel(c,h,'manual')
Which allows the user to pick the contours to label with the mouse?
