All,

In mp-grid.mp, I find this definition:

def hlingrid (expr Min, Max, Step, Length, Width) text t = image ( for i=Min step Step until Max+grid_eps : draw (origin--(Width,0)) shifted (0,i*(Length/Max)) t ; endfor ; ) ; enddef ;

See the text t at the end of the first line? Can someone tell me what that does and can I have a small example of its use?

I think, (I can not test it right now), that this should allow you to do things like hlingrid(0,10,0.1,5cm,3cm) withcolor 0.5white ; which will draw the line with 50% gray, and hlingrid(0,10,0.1,5cm,3cm) dashed evenly ; which will draw a dashed grid and so on.

t (text) is anything upto the ; so you can use it to pass things like 'withcolor red' and so Hans
