Hi Bruce, thanks for pointing out this bug. I will check the order of numbers, I have probably made some mistake when dealing with automatic color scale generation.
I have rewritten the scale code completely, but I had no time until now to write the docs. But if you want to try, something like that should now work in the layout: lookup altitude -title "Altitude legend" 700 [100 0 0] "700 m a.s.l." 680 660 640 620 600 [0 0 100] "below 600 m" endlookup It should generate red -> blue scale with desired values. Also explo-date, topo-date should now work with addition to maps, scraps. E.g. export map -layout-color map-fp topo-date and for example: lookup topo-date 2010.12.31 [] "2010 and before" 2011.12.31 [] 2011 2012.12.31 [] 2012 - [] "2013 and later" endlookup You may specify multiple lookup tables for same criterion using ":" separator in label lookup altitude:scale1 600 800 endlookup and lookup altitude:scale2 800 750 700 endlookup and use then "color map-fg altitude:scale1" or "color map-fg altitude:scale2" You may use also: lookup maps map1@some_survey [color] map2 [color] map3 [color] endlookup Same should work with scraps. With maps, also more simple way should work - you may specify color of a particular map within selection. select map1 -color [100 0 0] Also intervals should work: lookup altitude [1500 1600] [] "cave floor 1" [1800 1900] [] "cave floor 2" endlookup If you are willing to try, I would appreciate any feedback. Probably there are a lot of bugs because a lot of use-cases. I was not able to test them all. S.
