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. On 2 November 2017 at 10:05, Bruce Mutton via Therion <therion@speleo.sk> wrote:
I’ve just noticed that the latest development snapshot 5.4.1+4369eea seems to have messed with the altitude legend.
You can see from the screenshot below, which shows part of identical project compilations, one with 9d96803 and then one with 4369eea.
Pretty sure I have not made any other changes that could have caused this at my end, and I see that some of the intervening commits on github relate to colour changes.
Neutral (perhaps) changes are that there are more colour bands and the colours are brighter, in the legend at least, though not in the map.
A negative change is that the altitude range is now upside down.
