Choose a representation
Use a table for exact values, a bar chart for categories and a line chart for a series over time. Keep units and time periods visible and identify the source near the figures.
Build and check the data
Insert a chart or table, enter the real labels and values, and compare them with the original file. Preview the longest label and check how the scale affects the story.
Explain what changes
Use a live forecast block when the audience needs to change an assumption. For a fixed chart, state the observation and the limits of the data in the surrounding copy.
Example brief
How do I make a comparison fair?
Keep units and periods consistent across categories. Convert weekly and monthly figures using an agreed rule or label them separately. Check the source again after sorting the categories.
