May be a long shot, but I have data about how long in hours it took me to read each book, and the thickness of the book as well, and I want to plot this data in various ways. But because of the continuous nature of these things, I'd end up with essentially thousands of 'categories' on plots if I used tags. For example, I want to add up how tall the books I've read are in a certain time period, or how long I read for in a certain time period. I am currently using excel and bookly for these two things, respectively, but it would be cool to have it natively here!
