Hi Michael,<BR>
<BR>
On the subject of d.vect.thematic and drawing circles of varying size around points [perhaps not the best place to jump into this question], is there any way to have d.vect.thematic display points graduated according to exact values (e.g., diameters from an attribute column) rather than according to intervals, std. devs., etc.? A while back Hamish wrote this option into ps.map and I find it extremely useful.<BR>

</SPAN></FONT><BLOCKQUOTE><BLOCKQUOTE><FONT FACE="Verdana, Helvetica, Arial"><SPAN DEFANGED_STYLE='font-size:12.0px'>I hope I explain my problem properly. I have managed, with your<BR>
help, to visualise my gps data with v.neigbors, where v.neigbors<BR>
lets me specify the size of the neigborhood diameter and then counts<BR>
how many gps points fall within each neigborhood.<BR>
What I like to do now is to visualise gps data which has long and<BR>
lat, plus a value for the size of the neigborhood around each long -<BR>
lat co-ordinate, e.g.:<BR>
<BR>
51.298895 | 1.071705 | 0.1<BR>
<BR>
I don't want grass to count the frequency of gps co-ordinates which<BR>
fall into the neigborhood, as all of them have already been<BR>
eliminated from the data. So all I want grass to do essentially is<BR>
to visualise gps co-ordinates with varying circles around them.<BR>
<BR>
Thank you for pointing me into the right direction.<BR>
<BR>
Cheers,<BR>
Phil<BR>

Give d.vect.thematic a try.<BR>
<BR>
</SPAN></FONT></BLOCKQUOTE><FONT FACE="Verdana, Helvetica, Arial"><SPAN STYLE='font-size:12.0px'><BR>
for bubble plots also try 'd.vect.chart ctype=pie' with only one data<BR>
column, size column.<BR>
or try 'v.buffer bufcol=' (sometimes buggy)<BR>
