No, symbols cannot be offset at persent although I don't see why not. I'll
look into adding this. There are work arounds. You can use truetype fonts
as labels right? So there's no reason you can't use font symbols (i.e.
circles and other shapes) instead of text. Use the class "TEXT" parameter
to map a keyboard value to a symbol. With labels you can use the  normal 9
positions and can even offset futher with the OFFSET parameter. I've done
this in the past and it works fine. Note that because your label is
actually the symbol you can't label these symbols without another layer.

Hi,

Does anyone know if symbols can be offsetted from the point location?

OR

Can labels use symbols for the text instead of fonts?

I have to plot six different symbols, which could vary by six different
colours, around some point data.  The symbols need to be chosen by the
"year" attribute in the attribute table and the colour needs be chosen
by the "rate" attribute in the same table.

I thought that I could have six layers, one for each year, and then
colour the symbols by the "rate" attribute value.  Each year layer
could then be ploted on top of each other with the symbol at a
different offset to the point for each year.

Any thoughts to help me out?

Thanks in advance.


Johnh
