Which chart is ‘right’?


Twitter’s lighting up today over this remake of a Reuters chart. Which version is right?

Alberto Cairo takes the view that the y-axis should be topped at 25%, the better to view the fine-grained changes.

But JK Keller, creator of the remake, says that the distance from the 100% ceiling is entirely the point.

Which version is ‘right’? The answer is, ‘it depends.’ Are you telling the story of how far gender equality in the corner office has come in the past few years? Then you want to top that axis at 25% to preserve that detail. If, on the other hand, you want to show how far we still have to go, drawing the chart up to 100% paints a striking picture of that message.

Neither version is ‘right,’ making a great case study for how you can tell two very different stories with the exact same data.
