Hi Gert -
What about putting a column in that carries a city ID - populate that
column with an identifier on which you can select points related to
individual cities. If you can't currently save your query in the workspace,
it was probably a selection based on the Marquee or radius select tool
which doesn't allow saving into a workspace. Selection on a column using
Select or SQL Select is saved in the workspace so the results are
repeatable.
If you change all your point styles beforehand in the table itself (ie
circles, squares and triangles for different types of points or a range of
different point sizes) and not thematically, it makes the job a little
easier. To set the colours, map the table thematically, but apply "Color"
not "All Attributes" from the Styles tab in the thematic dialog and the
symbol type will stay as is is set in the file while the colour changes to
suit.
Hope this helps...

Subject: MI How to save thematic layer
OK.. here is what I'm trying to do....
I have a table of points covering the whole country, and I need to do
"individual point" thematic maps of these points on a City by City basis.
I don't want to cut my national point table into 52 individual table and
then have to update them all whenever a change is made to the national
table, and I don't want to do the thematic on the national table either,
because only a handful of the point values are relevant to each city,
leaving about 100 irrelevant point values to be turned off in the legend
for
each city , so...... it would be ideal if I could do the thematic on a
selection of only the points relevant to each city, but the selection does
not get saved with the workspace (unlike a query), so the thematic layer is
*gone* next time the workspace is opened.
I am sure I'm not the first one to come across this situation, so I am
hoping that there is a half way sane solution to it.
Also... is there a way to change the size of all the "individual point"
styles, without having to do them individually??
Any and all suggestions gratefully accepted.
