Thread: [Matplotlib-users] plotting a pcolormesh and fill

I have a pcolormest and a fill that are plotted on the same graph (they hav=
e
the same scale). Is there an easy way
to only plot the values of pcolormesh that lie in the fill?
pcolormesh(oX, oY, test, shading=3D'flat', cmap=3Dcm.gray_r)
fill([-x1,x2,x2,-x1], [-y1,-y1,y2,y2], 'b', alpha=3D0.2, edgecolor=3D'r')
--=20

Do you mean something like this?
ii = (oX > -x1) & (oX < x2)
jj = (oY > -y1) & (oY > y2)
pcolormesh(oX[ii], oY[jj], test[jj,][:,ii])
This assumes your oX and oY are 1-D, so you are plotting rectangular 
mesh. Correct?
