How do you chart the performance of a screener?

Stock Rover charts the return values of the tickers that currently pass a screener’s criteria as a group. The tickers that pass the screener are charted as if it were a portfolio with an equal dollar weighting for each holding. Additionally, via internal rebalancing, the equal weighting is maintained each day of the period that the screener is charted.

Can I use screeners for... Will custom metrics work in...
