If you want a general overview, then I would probably use the graphs available from here:
https://data.bitcoinity.org/markets/volume/. You can filter by specific exchanges and time frames.
If you want specific numbers, then use this site instead:
https://www.cryptodatadownload.com/data/. Choose the exchange you are interested in, then the market you are interested in, and you can get volume data down to the minute if you so desire.
