[gradsusr] geotiff kml question

[teresa tiberi]

hi,

I'm using in grads v2.0.a7.1 geotiff and kml code to obtain a colored
map of temperature, I attach the output files ...
I obtain output (geokml_*) using the kml code
 'set gxout kml'
 'set kml geokml_mediter_t2m_42
 'd t2-273.15'

if I try with geotiff code I obtain output (geotiff_*)
'set geotiff geotiff_mediter_t2m_42
 'set gxout geotiff'
 'd t2-273.15'

in kml case) the problem is that geokml_*.tif is all black in
googlemap and in a lot of graphic softwares.
in geotiff case) the problem is that geotiff_*.tif is in gray scale

could you tell me why?is there some problems in code?

and as last note: into
set kml <type> nome
-poly doesn't work.

thanks in advance for help

Teresa
