[mapguide-users] Is their a major flaw with theming point data?

[Dave Wilson]

I think the issue has to do with the fact that the coordinate of the point is not within the current map extent and hence does not get selected. The rendering happens after the fact so because the point is outside the extent it simply isn't rendered. I wouldn't call this a bug. I think the workaround is to create circular polygons.

Dave

Hi,
I have a circular buffer layer (data with x,y coordiantes in an Access
database) that is themed as follows:

50m - blue circle
500m - red circle
1000m - green circle
10000m - purple circle

The circles are symbols (.png images that are shaded but transparent).

Until now they have been working fine but I have just realised (after adding
the larger buffers) that when the center of the point is not visible on the
map the image does not show. This does make sense I guess because Mpaguide
is saying if the point is not visble on this mapview then it won't show it
but this is a major problem for me.

Is this a flaw with Mapguide?
Is there a way around this problem?
Is my best solution to convert all the point data in to circular polygons?

Any help or advice is welcome

Regards
JD
