A weekly chart needs consistent units before it tells a story

The chart shows a dramatic improvement

Suppose the weekly cash chart appears to show a strong recovery. Its vertical axis starts much closer to the latest balance than the previous chart did, making a modest movement look unusually large.

Check the display before drawing a conclusion. A chart can contain correct numbers and still make comparison difficult when scales, units or periods change without explanation.

Confirm the units and period

Identify whether the chart uses dollars, thousands of dollars or percentages. Check whether it covers a week, a month or another period and whether the latest period is complete.

Make those details visible in the chart or accompanying note. A familiar title is not enough if the underlying measure changed since the last meeting.

Compare with the source table

Match key plotted points to the supporting figures and investigate an unexplained difference. Check whether a missing value was treated as zero or whether a category was omitted from the display.

business.gov.au's cash flow statement guidance provides a structured view of incoming, outgoing and closing cash amounts. Keep that underlying numerical view available so the chart can be checked rather than accepted only on appearance.

Use scales that support the question

Choose a consistent display for period-to-period comparison, or explain clearly why the scale changed. A detailed view of a small movement can be useful when labelled appropriately.

Do not assume every axis must follow one universal rule. The practical requirement is that the audience can see the size and context of the movement without being misled by an unexplained presentation choice.

Separate visual movement from business meaning

Ask what caused the underlying change and whether it affects a decision. A prominent upward line may reflect a one-off receipt, while a small-looking movement may matter because it crosses a critical cash level.

Keep the explanation tied to the actual figures and obligations. The chart should help the discussion, not substitute for the reasoning behind it.

Check one chart before the next meeting

Review the units, dates, scale and source values of the chart management relies on most. Add a short note for any change from the previous version.

Retain the underlying table with the meeting pack. A clear visual backed by traceable numbers makes the weekly review easier to understand and reduces the risk of a presentation change being mistaken for a business result.
