Hello, I use xgrid() with plot2d(), like this (default mode) > plot2d(0,0,rect=[0,0,10,10]),xgrid(31) > plot2d(1:10,matrix([1:5;1:5],1,-1),frameflag=0) In old scilab version, the grid is drawn below the curve, but with scilab-4.0 it doesn't work. How can I make a grid under the curve? Thanks for your help. -- Jyb
