Quoting Bruce Mutton <bruce.mutton@paradise.net.nz>:
Ah, Stacho. Two types of grids! That explains part of my conundrum. Now that I know it exists I'm not sure what the map atlas grid might be for?
To show atlas pages layout, when "export atlas" is used.
The other relates to the co-ordinate grid; illustrated by the attached pdfs, scaled at 1:1000. When specified as 10 10 10 I get nice continuous grids, but when specified as 50 50 50 or 100 100 100 (and no other changes) I get cross hairs, which are not too my liking.
You get 1cm cross-hairs also in 10 10 10 grid, but they are too close to each other :) Just redefine grid symbol to receive solid grid -- i.e. add following lines to your layout: code metapost def s_hgrid (expr xpos, ypos, xsize, ysize) = pickup PenD; draw ( if xpos < 0: 0 else: -xsize/2 fi, 0 ) -- ( if xpos > 0: 0 else: xsize/2 fi, 0 ); draw ( 0, if ypos < 0: 0 else: -ysize/2 fi ) -- ( 0, if ypos > 0: 0 else: ysize/2 fi ); enddef; endcode Regards, S.
