You will need to either choose a predefined 'area blocks'
that does not have<br>
a solid fill from the standards available - currently AUT
and SKBB are the<br>
only unique ones I think - and quite possibly they are both
filled.<br>
<br>
Or you will need to modify the existing definitions.<br>
<br>
I have no time to check just now, but you might like to have
a look at what<br>
I did here <a moz-do-not-send="true"

target="_blank">http://therion.speleo.sk/wiki/doku.php/examples</a>
(Sample dataset<br>
at the top of the page) and modify it a bit to see how it
behaves with<br>
colour assignments.<br>
