The raw number of transactions is a problematic metric, because it doesn't really tell you as much as you'd initially think it does.  

It's worth considering the significant impact of transaction batching for starters.  One transaction can be used to transfer value to multiple recipients.  Prior to 2017, many Exchanges were pretty reckless in terms of not batching transactions and wasting available space.  Most have reformed their ways since then.  More people can receive payments using fewer transactions now.

Conversely, not every transaction is an actual transfer of value from one person to another.  Sometimes users are just moving funds from cold storage to a hot-wallet or vice-versa.  Some transactions are merely for other blockchains, altcoins and certain services to leverage Bitcoin's security for their own means.  Transactions like this are not indicative of any kind of economic benefit to Bitcoin.

If you're trying to use any of this information to read into market price swings, it starts to look pretty tenuous at best.
