Davison Chart

The Davison chart (also known as 'relationship chart') is one of a number of techniques for assessing the compatibility of people, and the characteristics of a group dynamic. It can be used an alternative - or an addition - to synastry, but it has wider application. For example, Davison charts are typically cast for two men. The characteristic of the Davison chart is that it is not theoretically limited in the number of nativities that can be subsumed into one chart.

Davison charts can utilize a variety of methods for the technical averaging of the birth details of the individuals. The method used in ZET results in a chart which can be progressed, transited, etc (unlike the better-known composite chart).

To erect a Davison chart:

  1. Open the Database window,
  2. In the left pane, select the table that contains the natal data for the members of the group,
  3. In the right pane, right-click the mouse on an individual line to display the database popup menu, and select the "Mark for combined Chart" item. Alternatively, right-click on the gray cell at the left of the line of data. (If you mark a line in error, right-click again on the cell to unmark it),
  4. Repeat the previous step to mark all nativities of the group in the same way,
  5. Right-click in the database table for the database popup menu for the final time, and select "Cast Davison Chart".
