I have 3 prices that I want to plot in a single chart. Below are the two queries. The time values for both tickers may be slightly different.
select time, change_percentage from stock_prices where ticker in ('QQQ') order by time asc
select time, change_percentage from stock_prices where ticker in ('VTI') order by time asc
select time, change_percentage from stock_prices where ticker in ('TSLA') order by time asc
