Return the lot details, group the lot details, and compute the number of each lot details, and could you show x-axis in descending order?
SELECT lot_details, COUNT(lot_details) FROM Lots GROUP BY lot_details ORDER BY lot_details DESC
SELECT "lot_details", COUNT("lot_details") FROM "Lots" GROUP BY "lot_details" ORDER BY "lot_details" DESC
