The deck is due at noon. Slide 7 is the chart that took you two days, the one where you finally saw it. And in the meeting, after four seconds of silence, someone asks the question that erases all two days: "So... what am I looking at?"
The tip
The title is the most-read ink on any chart, so spend it on the finding, not the filing label. "Return rate by branch (W1–W12)" describes the data. "Maadi's return rate doubled in six weeks; every other branch held flat" delivers the analysis. Write the claim; make it the title; then make the chart keep the title's promise.
The how
1. Write the sentence first. Before touching the chart: the one sentence you'd say to the decision-maker if you had four seconds. If you can't write it, stop; the chart isn't ready because you're still exploring. (Exploration charts are for you; claim charts are for them. Different animals, see the Catch.)
2. Promote the sentence to the title. Plain words, sentence case, numbers welcome. The variable description doesn't die; it demotes to a small subtitle: "Weekly return rate by branch · W1–W12 2026." Everything the old title did is still there; it just stopped hogging the headline.
3. Make the ink keep the promise. A claim title is a contract, and the chart pays it: the series the claim is about gets the accent color; everything else grays into context; the moment of the claim gets an annotation on the data ("packaging change, W6"); and if direct labels can replace the legend, the legend dies—a legend is a puzzle, labels are answers.
4. The two-way cover test. Cover the chart: does the title alone tell a stranger what to conclude? Cover the title: does the chart alone point at the same conclusion? Pass both; ship slide 7.
The before/after pair above is the whole argument in one glance: identical data, and only one of the two can survive four seconds of executive attention.
The Catch
A claim title converts your chart from exhibit to testimony, and testimony carries a higher burden of proof. Two boundaries, same root. Never claim-title an exploration chart: while you're still analyzing, a headline conclusion anchors your own eyes, and you'll stop seeing what disagrees with it, in the notebook, descriptive titles are correct. And the claim must not outrun the ink: if the title says "doubled," the axis had better show doubling honestly, no truncated y-axis theatrics and no cherry-picked window. The moment the title argues, the chart is under oath.
File this for the next deck. Slide 7 deserves a verdict, not a caption.
