SV: SV: [GRASS-user] Raster legend

[Martin Album Ytre-Eide]

I am getting more confused by each time I try to edit the conf-files.

To be sure I get your suggestions right, I send you my conf-files.

The log.raster conf-file:
% 2.658010959625244140625 5.07434749603271484375
2.658010959625244140625:0:191:191 3.1412782669:0:255:0
3.1412782669:0:255:0 		  3.6245455742:255:255:0
3.6245455742:255:255:0 		  4.1078128815:255:127:0
4.1078128815:255:127:0 		  4.5910801888:191:127:63
4.5910801888:191:127:63 	  5.07434749603271484375:20

The non-log.raster conf-file
% 443.143585205078125 100252.296875
443.143585205078125:0:191:191 20404.9742431641:0:255:0
20404.9742431641:0:255:0      40366.804901123:255:255:0
40366.804901123:255:255:0     60328.635559082:255:127:0
60328.635559082:255:127:0     80290.466217041:191:127:63
80290.466217041:191:127:63    100252.2968751:20

The result from r.what.colors whit converted log-values.
447.000000: 0:191:191
1738.000000: 0:195:179
6607.000000: 0:210:133
25704.000000: 67:255:0
100000.000000: 23:22:21

I tried to apply this values in the non-log.raster conf-file as suggested by Nikos, but without any luck. The legend values still wants to be linear.

If you still want to help, you could maybe make me a conf-file in the way you think it should be.

Thanks for all the help so far.

Maybe it's not that clear, but (as Hamish, again, note) it's possible to
draw any legend on any raster map. So,

# draw log.rast
d.rast log.rast

# draw non-log.raster (after having found correspondence of log ~
non-log values and colors)
d.legend non-log-legend
