here's a quick thing which is quite annoying me. I've followed the indications found in strange matplotlib zorder behavior with legend and errorbar but it doesn't work. Here's a very brief working example

x = np.linspace(0,10) 
y = (x-5)**2 
plt.plot(x,y,label='test curve',zorder=100)
plt.legend(loc='center right').set_zorder(102)

If you try this you will see that the legend is still underneath the curve, despite the zordering. Does anyone know why?

I'm using matplotlib 1.3.1 on ipython 3.1.0

    To me it seems that legend and curve are in the right order, but the legend rectangle does not have an opaque background. I tried this with `matplotlib 1.4.3` and the legend is opaque. – cel Nov 11 '15 at 11:26
  • Also tried `matplotlib 1.3.1` and this works as well for me. Maybe a backend issue? – cel Nov 11 '15 at 11:41

Following on from @cel's comment, I agree you need to add an opaque background to the legend. Try adding:

leg=plt.legend(loc='center right')
leg.set_zorder(102)
leg.get_frame().set_facecolor('w')

Its also possible to set legend.facecolor in your matplotlibrc or via plt.rcParams

Alternatively make sure the fill of the legend frame is set to True:

print leg.get_frame().get_fill()

If that prints False, try

leg.get_frame().set_fill(True)
