Find those years for all exhibitions with ticket prices lower than 15, return a bar chart that groups by year and counts the total number of years, I want to list y axis from high to low order please.
SELECT Year, COUNT(Year) FROM exhibition WHERE Ticket_Price < 15 GROUP BY Year ORDER BY COUNT(Year) DESC
SELECT "Year", COUNT("Year") FROM "exhibition" WHERE "Ticket_Price" < 15 GROUP BY "Year" ORDER BY COUNT("Year") DESC NULLS LAST
