I checked and I can confirm what Bruce is saying. If you don't include centerline in map, the altitude range is correct.

If you hide the centerline in the layout (leaving it in the map) the altitude range keeps starting from 0 m.

I am not seeing this Bruce. I just tested with 5.3.16. My survey imports the centreline from a Survex .3d file however, so that might make a difference? Or maybe I am not understanding what you mean by including the centreline in the map. I turned off the centreline using 'symbol-hide line survey'. If I comment that out in my layout then the centreline is drawn in the map, but my altitude range still covers only the range of my scraps.

OK, the problem is not the previews or the offsets, as it occurs in the map examples below regardless of presence of previews or offsets.

What does seem to control whether the altitudes start at zero meters is whether the map definition includes a survey centerline.

 

If part of map definition includes a survey centerline, then altitudes are coloured from zero meters to survey maxima (a bug?).

If map definition has no survey centerline as part of it’s definition, then coloured from survey minima to survey maxima (correct behaviour).

 

Hence I find this behaviour manifests in maps in progress, but when they are finished and I (usually) turn off the centerline maps, they correct themselves.

Hmm, seems like there is an issue here.

Comparing 5.3.10 map with 5.3.16 map as attached.

 

Not sure if it might be a side effect of something else, as I think the colour range is OK sometimes (I think I noticed some irregularities with 5.3.15 but assumed I was imagining things at the time) – maybe the preview below triggers it?  - I might investigate further if I get time.

Subject: [Therion] Altitude colors range

 

Hello,

I use to color maps by scrap altitude. 

 

Lately I noticed Therion color gradient starts from 0 m altitude to maximum cave altitude. Because caves don't reach 0 m almost all color range is unused and most scraps are colored with similar colors. If I remember correctly some time ago Therion used all color range because color gradient extended from minimum cave altitude (not 0 m) to maximum. 

 

Am I missing something? Is there a way to use all available colors?

 

Thanks,

Marco
