Multi Relationship Chart A*C*G Map

I've started to examine Astro*Carto*Graphy maps drawn for a multi relationship chart to find out if they provide additional information about locations for a group of people.

A multi relationship chart is calculated for three or more people, using the midpoint between all the dates, times and places of birth. This chart is then used to draw an A*C*G map. It is also possible to use Cyclo*Carto*Graphy on a multi relationship A*C*G map.

The main problem in calculating a multi relationship is finding software to do this. Solar Fire is able to calculate a group composite chart, but not a multi relationship chart. The program I am using for the multi relationship chart A*C*G map is ZET 8. Using this program it is very easy to calculate and draw a multi relationship chart A*C*G map. From what I have seen it would appear that ZET 8 is the only program available that has this feature.

I will write more about the multi relationship chart map after I have done some research with them.
