Hello,
I have some minor questions regarding matplotlib. I'm using it to make a 3d
plot, displaying a surface, it's contour map, a line climbing the surface
and its projection onto the contour map.

As you can see, when the lines cross the contourf, they are somewhat
obscured. Before I made the contourf transparent, the lines were blocked,
even though they were above the contour plot when I viewed the picture from
a different angle. Can this be fixed? I want the lines to appear on top of
the contour plot.
Also, I am trying to extend the z axis to be lower. This is most of the code
I'm using:
fig=plt.figure(1)
ax=fig.gca(projection='3d')
x=np.arange(0,2.5,.02)
y=np.arange(0,2.3,.02)
x,y=np.meshgrid(x,y)
ax.plot_surface(x,y,Z(x,y),alpha=0.3)
cset=ax.contourf(x,y,Z(x,y),zdir='z',offset=-2,
cmap=plt.cm.jet,levels=np.linspace(0,9,100),alpha=0.5)
ax.set_xlabel('x')
ax.set_ylabel('y')
ax.set_zlim(-2,8) #This is where I try to change the z axis limits.
plt.show()
I'm excluding the code which plots the lines. ax.set_zlim doesn't do
anything; why is this?
