Two dimensions, one measure: how to show data the best way ?
I have two dimensions (let's say: purchase date, delivery date) and one measure (let's say: order amount).
Now, I want to show which pair of dates has the highest order amount. I was thinking to something like a scatter plot (with dimensions on axis and maybe with smart data compression, since I've a lot of dates...) and emphasize the most valued pairs with a color shade but, of course, that chart handles one dimension and two measures.
Which kind of chart (even from "branch.qlik.com") do you think I could use, to have the best user experience ?
