While doing ashtakvarga calculations, it is found that the charts provided by software are incomplete.
The Bhinnnashtak of Lagna (ascendant) are not shown.
Similarly, in Sarvashtak charts, Lagna (ascendant) is not shown.
Actually, 7 planets (Sun, Moon, Mars, Mercury, Jupiter, Saturn & Venus) & Lagna (ascendant) form the ashtak
But your calculators do not show the points of Lagna in any chart, making it incomplete.
(I am unable to attach pictures in this form, hence unable to show them here)
