HAProxy does not output historic data about past requests (nor would
Prometheus be able to scrape it), so you'd have to scrape the HAProxy
exporter for 24h, 2 days, etc., to get that amount of history into
Prometheus.
Then you can query for e.g. the average request rate per second over 24h
("rate(haproxy_frontend_http_requests_total[1d]") or the total number of
requests happening in 2d
("increase(haproxy_frontend_http_requests_total[2d])").
