A 90 degree dial is a kind of chart wheel that is used in the cosmobiology and uranian schools of astrology. The 90 degree dial was used extensively in the 1960's and 1970's, just before personal computers were invented. Some users of the Kepler program find 90 degree dials very useful today, even though some of the data which is seen in the 90 degree dial, such as midpoint structures, can be calculated and printed directly.

In Kepler, you can produce a 90 degree dial, and also BiWheels, TriWheels, and QuadWheels in 90 degree dial format. You can also put 2, 3, or 4 separate 90 degree dials on one page, and you have a choice of color schemes. Samples of some of these features are shown on this page.
