1. Choose a chart for the question
April is EUR 600 and May EUR 590: a EUR 10 decrease. Bars start at zero, labels identify completed line value and the table gives exact values. Two months do not establish a durable trend.

2. Build visual hierarchy and accessible alternatives
A useful description is: completed line value was EUR 600 in April and EUR 590 in May 2026, a EUR 10 decrease in a fictional snapshot. The table carries the same values; neither colour nor an image alone carries the finding.

3. Audit misleading comparisons
AOV rises from about EUR 54.55 to EUR 59, but completed value falls EUR 10 and order count falls by one. This descriptive comparison cannot establish why the mix changed or whether an intervention worked.
