seems expected behavior. please add more details.
this is expected behavior. since the sharing case, chart does not create query by itself, just shares the table's query. so this is a implicit limitation that chart can just use top group of shared table in y optional expression. if chart allows any expressions to be set in y optional expression against sharing case, the result of chart render might be unexpected by user.
