Re: [Therion] Cutting off a grid
hi,
1. had the same problem a while ago (was also looking to place the height labels differently).
Lines can not be cut off (or at least was not in 5. Only solution is that u make the grid smaller). Although it would be nice if the first and last line could be cut off
2. last number in grid-origin should be the height of ure entrance (If ure entrance is 405m high: grid-origin 0 0 405 m)
This changes only where the line is placed, so it would start at the entrance but label would show 405m
But, it would change the output of point-altitude as well, that will start then at 0

Betreff: [Therion] Cutting off a grid
Hi,
We have a vertical cave that is just over 100 metres deep, with its
entrance just below a 100 metre contour.
We want to show a grid on the elevation view, like this:
#show an altitude grid every 25 metres
#("50 50" affects only plan view, so is ignored here)
grid bottom #behind the cave
grid-size 50 50 10 meters #one line every 25 metres of depth
grid-coords border #show numbers at the edge of the survey
This leaves a 20+ metre gap at the bottom, since the cave only just made
it past the last 25 metre grid line.
1. Is there a way to cut off the grid after a certain amount, so that it
doesn't show the blank gap at the bottom? Or alternatively, cut off the
grid after the cave ends? Or "show the next grid line if the cave is
within 5 metres of it"?
2. Is there a way to start the grid at "0" at the entrance to the cave,
in order to show depth below the entrance instead of the altitude above
sea level?
I tried this:
grid-origin 0 0 400 meters
But Therion just threw an error with no error message, so I am obviously
doing something wrong. Does that only work in plan view perhaps?

Hi, there is a bug in the embedded shapefile library if it's used under Windows. The latest commit contains a local fix, so it should work well now.

Umm, yeah. That should have been "50 50 25"

Anyway you may add blank PDF or png to your map to cover part of grid: map-image Martin ___ Therion mailing list Therion@speleo.sk https://mailman.speleo.sk/listinfo/therion
