[Request] Historical data/plot of issued asset supply over time

[effofexx]

Please consider adding a plot showing the total supply of an issuer's assets over time. For black holed accounts this feature would be useless, but I believe it would be insightful for assets issued by gateways such as Bitstamp USD and GateHub USD.

We can look at the order books for pairs including Bitstamp USD (for example) to assess the current state of that asset's liquidity, but it says nothing about that asset's potential liquidity and market depth taking into account the amount sitting idle in wallets. We can also currently view the total issued supply on XRPScan as printed text, but it doesn't tell us how that amount compares to prior amounts. By viewing a plot of the issued amount over time we can better understand whether or not an asset's popularity is increasing or decreasing, and can help users decide if they should consider a trading strategy involving that asset based on its relative availability.

I also think this would be nice to have simply as a record of historical XRPL metrics, and as a way to identify potential trends.

Thank you for taking the time to consider my suggestion.

Hi @effofexx, thank you for providing this detailed RFE. Really appreciate it. There are a few projects that track historical XRP balance, but there's a need for tracking issued tokens too.

Backfilling this data by replaying transactions is compute intensive. Perhaps these type of queries can be handled easily by Project Clio - i.e. something that runs atop Postgresql? Can't commit when this will can be PoC'd, but we need to wait for a better alternative to querying full-history service.
