Hi Frank,

You need to specify the range option as range=0,8 (instead of range=0-8 as you did).

Cheers
Stefan

Hello grass users,

I have an error message in the console when I open some rasters with witch I've done a r.category.

"Failed to run command 'd.legend
raster=ZVT_nac_projet_hoht2__BDalti75_a1_8_sum at derval title=nacelle color=white range=0-8 at=5.0,50.0,6.9,9.9 thin=3'. Details:

ERROR: Option <range> must be provided in multiples of 2
     You provided 1 item(s): 0-8"

I don't understand what the error message means (in red color in the
console) ?

Thank your for your help !
