Comment (by hamish):

 Using the range= and labelnum= options you should be able to get the look
 you are after.
 {{{
 d.legend range=0,-200
 }}}
 then you get labelnum=5 ticks at: 0,-50,-100,-150,-200

  * adjust your color rules so that they cover the full range
  * with the range= option do max,min instead of min,max to flip the legend
 vertically (or use the -f flag)


 see also ps.map's colorbar legends. They work the other way and try to
 fall on round numbers automatically. Both ways have their merits, but I
 guess I hear less complaints about the ps.map way. (but less people use
 that, so who knows)
