You can use Statistics > Logs Per Date and Logs Over Time to produce a zoomable graph of your find stats. Zoom in to the date range of your trip. You can couple this with cache type. However this only gives total finds per day, not by type.
Would be a nice statistic to add - cache finds per type, with two sliding scales, start date and end date, defaulted to 1/1/0000 and 31/12/9999.
