The horoscope Chart tableau is displayed by default when ZET starts. You can redisplay the tableau at any time by:
This topic describes the main features of the Chart tableau, and the
concept of data sets used to create different types (single, dual, and multiple)
of horoscope chart.
To read about the procedure for entering birth and/or life event details and casting
an astrological chart see Event Data.
The Chart tableau is interactive - the graphical display is the human/computer interface. Glyphs and texts are sensitive to mouse actions: pausing the mouse pointer over them, left- and right-clicks, double-clicks... experiment!
Adjustment of the chart graphic
The contents of the tableau and their dimensions and sizes can be customized to suit personal preferences, work flow, hardware capability, etc. Adjustment is done thru the various tabs of the Chart Settings window.
The Dynamic Tooltips: Position the mouse pointer over any element of the chart, and you will see a small yellow window appear nearby with the item's description (its name, or some other information). (Their color may be different if you have customized the Windows Desktop). You can disable these 'info tooltips' if you prefer, and set the length of time it takes for them to appear and disappear.
The 360° Protractor:
Click the mouse inside the ring of planets (i.e. on the central disc with
criss-crossing aspect lines), and hold down the mouse button. A graduated 360 degree dial
appears in the center of the wheel. Drag with the mouse in a circular motion to rotate the
dial to any degree of the Zodiac.
Rotating the Chart:
Move the mouse pointer over the inner border of the multicolored
Zodiac ring, and wait a moment for the mouse pointer to become a circle with
arrowheads. Press, and hold
pressed, the main mouse button and move the mouse. The chart wheel rotates and the tableau
is fully updated as you rotate the wheel: displayed time, planet positions, aspects formed,
and other time-dependent information. This action causes the 'current time',
i.e. the time of the implied event, to change, and the Event Data window contains the new time.
You can also drag the glyphs of the main planets (Sun thru Pluto) in the same way, and with identical effect. Observe that when Sol is dragged the time changes in increments of one day, and when Luna is dragged, the time changes in increments of one hour.
Zooming and Shifting: Click the mouse on the large bullet at the right side of the Toolbar (tooltip: "Zoom In (Pg Up)") to magnify the wheel. Magnification up to 8x is possible. To revert to lower magnification, click the adjacent button with the point ("Zoom Out (Pg Dn)"). The chart wheel can be shifted to view any magnified portion by holding down the Shift key and clicking and dragging the tableau with the mouse.
Viewing the dynamics of an aspect: Left-click on an aspect line in the central region of the wheel to display the Dynamics Diagram for the aspect. This window shows the progress of the aspect as it develops over time, which is frequently more complex than expected. NOTE: declination aspects (shown on the wheel as arcs) must clicked on in the middle of the arc for their Dynamics Diagrams. See also the planet popup menu below.
Viewing the Sabian Symbols: Position the mouse pointer on the outermost edge of the wheel so that a white rectangle appears under the stem of the pointer shape, and press and hold the main mouse button - a blue line appears as a radius-vector on the wheel, and the Degree Overview window is displayed. You can drag this 'arm' with the mouse to rotate it to any degree. The Degree Overview window contains the Sabian symbol interpretation of the degree of the Zodiac and other relevant data for the degree (the properties of the window are customizable) .
Popup Menus: The Chart tableau has several popup menus, depending on where the mouse pointer is placed.
Right-click on a planet glyph for a popup menu of information and options for the planet:
Right-click on a house number or cusp number for a popup menu similar to the planets popup menu just described. (NOTE: the Aspects Grid displays aspects to a house cusp only if the house cusp has been selected for inclusion in the Aspects Grid - see Chart Settings - Aspects). The popup menu includes these additional items:
Right-click on a Zodiac symbol in the zodiac ring of the wheel for a popup menu for that Sign:
Clicking on an aspect symbol or line effects the following (declination aspect lines should be clicked centrally):
Double-click in the Chart tableau to display the Chart Settings window. From this multi-tabbed window you can select many different options for the chart, and immediately view their effects.
Right-click in the tableau to display the Chart tableau menu with the following options (click the links for more information):
The basic charts of astrology use just one set of time, date, and place data for their erection. Examples of such 1-data charts are the natal chart of a person, and the horary chart, which is erected for a particular moment deemed to be significant, e.g. the intiation of a business enterprise. Different rules apply to their construction and interpretation according to their purpose.
1-data charts are referred to in this User Guide as single charts.
A significant part of astrology involves interpreting two sets of event data in relation to each other. Sometimes the requirement is simply to compare two events directly, e.g. a synastry comparison of two people (nativities), or a transit chart, which considers the effect of planets at some date on a natal chart (rules of interpretation are different).
A number of prognostic techniques, however, require symbolic transformation of the event data for some time and place after (and occasionally before) a birth, as a prerequisite to comparing it with birth data. These are the variously designated progressions, directions, etc, and the resultant chart is interpreted both on its own terms and in relation to the birth chart.
2-data charts are referred to in this User Guide as dual charts.
When working with two sets of birth or event data, ZET distinguishes them as Core and Background (these are ZET's terms). The background data set typically undergoes transformation in prognostic techniques.
You can think of the core data set as central to an issue and to the chart wheel since, to erect a horoscope for a nativity or an event, some basic data must be entered, and ZET displays the result on its inner chart wheel. Dual charts on the other hand involve comparing some fixed baseline (main, central) data - typically a nativity - in a context (against a background) which is up for selection - for example, a prospective marriage partner, or the start date of a project. This background data is displayed astrologically on the outer wheel.
To see how these fit together in different types of chart, consider the table:
The distinction between core and background data is astrological and terminological. ZET has no in-built preference - the facilities for operating with core data can also be applied to the background data.
ZET can display up to 7 charts resulting from multiple techniques on the wheel, using a separate ring for each set of planets - see Complex Charts. However, at most two dynamic data sets (core and background data) underlie these charts. Other non-adjustable 'fixed charts' can also be included, but they are static.
See Prognostic Charts for information about the techniques available in ZET.
More recently astrologers have devised techniques which allow more than two sets of astrological event data to be reduced to a single chart. The resultant chart may or may not be real, i.e. describe a set of positions that the planets could in reality adopt. Such charts, however, allow scope for the interpretation of otherwise intractable many-factored situations. Examples are the Davison relationship chart, and the (Hand) composite chart.
In ZET these N-data charts are erected via the Database window, not the Event Data window.
To interactively adjust event data, and to animate the chart wheel,
Dynamics of Time and Dynamics
of Location, but note:
The glyphs of planets, etc can be customized. When ZET glyphs are used, typing Alt+F accesses the built-in Glyph Editor for creating and editing astrological symbols. This operates in a manner similar to other icon editors, for example, for creating Windows desktop icons. Alternatively, the main glyphs can be obtained from an astrologically-enabled TrueType (continuously scalable) font - several can be downloaded from the ZET Web site. ZET glyphs will still be used for minor bodies. ZET does not have facilities for editing TrueType fonts.
