Select the vector map in the list and press the thematic icon. It <BR>

</SPAN></FONT></FONT></BLOCKQUOTE><FONT SIZE="2"><FONT FACE="Monaco, Courier New"><SPAN DEFANGED_STYLE='font-size:10.0px'>OK. I’m working on this. I’ve got the basic interface done and now need to add in the thematic code. The main issue I see at this point is how to create even a text legend. I thought I might be able to do it using d.graph, but this only shows the standard GRASS colors AFAICT (.e.g., red, green, blue,...). I need to learn how to send tcltk output to a new and different window. I can get it into a file, but users will want to <B>see</B> the results without opening the file.<BR>

This depends first on whether the GRASS subset of SQL will produce a unique value query. This is the easiest way to go, but I don’t remember seeing the ‘unique’ keyword in the SQL list. There are other ways to do this (the way I did v.lda, for example) but they aren’t as straightforward.<BR>
