RE: [GRASS-dev] gis.m: cannot get profile from profile tool

Hi guys,

I tried the porfiling tool with July 31 cvs, and I can't get it to work. The
y-axis gets assigned correct values for the profile I've drawn, but no lines
get drawn in the profile window. A tcltk window reports "Error: can't read
"cumdist": no such variable"

You can view the output on my ftp site:

Hi Moritz,

Did you select a raster to profile?

Yes, as you can see in the screenshot, it says in the bottom left:
"Profile for srtm_be".

Third button from the left on the
profiler toolbar.
Rather like d.profile, the profiler differentiates between
a map you use as a background to the profiling line (what is shown in

the

map display) and the map that you actually use to compute profile

values.

I understand that, but I still don't get a profile. Actually, I
sometimes do not even get the straight blue line you see in the
screenshot (http://moritz.homelinux.org/grass/gism_profile.png), just an

empty graph.

The min and max of the heights on the y axis seem correct, though.

Eric,

You failed to select a raster map to profile.

I just committed an update which does a better job of trapping this kind of
error and giving you a more meaningful error message. I also made the
profiler default to the currently selected raster map to profile and also
found a way of making the elevation ranges calculated within the currently
displayed region, using r.univar. The primary drawback of this is that it is
a bit slow to get started with enormous maps.

I actually got a similar error at one point, but then couldn't reproduce it...
