Portfolio chart including cash

I’d love for the chart showing your portfolio value over time to be inclusive of any cash holdings, rather than ‘portfolio’ value (investments +/- return).

This would make the chart a bit more meaningful for those who may not be fully invested at all times.
I hold varying levels of cash as I buy/sell, but that doesn’t mean my overall chart should step up/down?

And thinking about that, how about your ‘Return’ % be the gain/loss on total (or net) deposits instead?
