Column chart Jan2025FebMarAprMayJunJulAugSepOctNovDec05,00010,000 Columns rise from a shared baseline like stacks of stuff, each one a total compared by height. Use them for counts and amounts across a handful of categories or periods. Always start them at zero, because a cut-off column misstates its own size. Playfair, who published some of the first bar charts, explained the idea with a pile of coins: “Suppose the money received by a man in trade were all in guineas, and that every evening he made a single pile of all the guineas received during the day . . . time, proportion, and amount, would all be physically combined” (William Playfair, The Commercial and Political Atlas, 1786).
