Is it possible to have some explanation of the parameters of the macro numberstriped(#1,#2,#3) ? How to have horizontal hatching ? (How to change the slope hatching ?)

There is also anglestriped in mp-tool with some examples. The second argument changes the angle. \startMPpage[offset=2mm] path p, q ; p := unitsquare scaled 4cm ; z1 = point 3.6 of p ; q := subpath (0,2) of p -- z1 -- cycle; q := q shifted(-4cm,-4cm); draw q anglestriped(1,180,6) withcolor blue; draw p ; \stopMPpage (I have not yet found why the striped path q goes out of position. Looking at mp-tool may help.)

I just noticed that the position of labels is not quite the same when using macros and macro Metafun Metapost: I think the labels are too near to the corners of the square with the macro Metafun.

Try the mpost variable lableoffset := ? to adjust. HTH, John
