the "chart" cell makes it easy to build basic charts, but you have to watch out, sometimes it's too easy. here it gives you the result without all fields specified, but is it the result you want? it's always good to test a couple of datapoint and see if they match the data, so let's test that the first blue bar is 5840 of "classic" in California, ok let's filter the original data to keep only what this bar needs to show: filtered = pizzaorders.filter(f => f.category === "Classic" && f.state === "CA") // => Array(5840) this gives us an array of 5840 items. now if you take a SUM of orders in each record you get this: d3.sum(filtered, d => d.orders) // => 659315 your blue bar is two orders of magnitude off... if you look at your settings you may notice "∑Auto: count" see? it just counted the rows in California, not the orders it takes 4 clicks to fix this issue and you will have a very different graph. let me know when i can come back to check, don't be shy to ask others for help

solved!

again this is not exactly showing what you claim it should, the solution is 4 clicks away too

solved!

same struggle here. because of the mistake you don't see workday to weekend variations either

solved!
