Hi,
I'm having problems with using thematic maps in Grass 6.2RC2. If I try to display *any* vector thematically (including the spearfish dataset), then I get the following error:
can't read "lineht": no such variable
while executing
"expr {$lineht * 2}"
(procedure "GmThematic::tleg_item" line 19)
invoked from within
"GmThematic::tleg_item $mon $id"
(procedure "GmThematic::display" line 73)
invoked from within
"GmThematic::display $node $mod"
("thematic" arm line 2)
invoked from within
"switch $type {
group {

}
raster {

}

(procedure "GmTree::display_node" line 7)
invoked from within
"GmTree::display_node $n $mod"
(procedure "GmGroup::display" line 22)
invoked from within
"GmGroup::display "root" $mod"
(procedure "MapCanvas::runprograms" line 63)
invoked from within
"MapCanvas::runprograms $mon [expr {$mymodified != 0}]"

invoked from within
"MapCanvas::drawmap $mon"
(procedure "MapCanvas::display_server" line 9)
invoked from within

Anybody got any ideas or workarounds? I think this may have already been posted under grass 6.3 development - apologies if this is a mis-posting, but I could really use a quick fix!
Thanks
Alex
