Check Labels First

Start with three pinned rows for daily orders. Before reading the bar heights, check that the chart says what it shows: title Daily Orders, x label day, y label orders, and units orders. Then the value 8 means 8 orders on Tuesday, not 8 dollars, 8 visits, or an unlabeled number.

A tiny chart-label readout: check the title, x label, y label, and units before reading values from a chart.

Read values after labels

Read values only after the labels say the bars are order counts.
