CREATE TABLE College (cName VARCHAR2, state VARCHAR2, enr NUMBER)
CREATE TABLE Tryout (pID NUMBER, cName VARCHAR2, pPos VARCHAR2, decision VARCHAR2)
CREATE TABLE Player (pID NUMBER, pName VARCHAR2, yCard VARCHAR2, HS NUMBER)

Show me a bar chart for what is minimum hours of the students playing in different position?, I want to display by the total number in descending please.
SELECT pPos, MIN(T2.HS) FROM Tryout AS T1 JOIN Player AS T2 ON T1.pID = T2.pID GROUP BY pPos ORDER BY MIN(T2.HS) DESC
SELECT "pPos", MIN("T2"."HS") FROM "Tryout" "T1" JOIN "Player" "T2" ON "T1"."pID" = "T2"."pID" GROUP BY "pPos" ORDER BY MIN("T2"."HS") DESC
