Perform Variance Analysis Using Area Charts in Power BI

Area charts are a powerful way to visualize project performance over time.

In project controls, the data date is often placed on the x‑axis, making it easy to track planned vs. actual progress across updates.

With an area chart, you can:
• Plot planned cost against earned value cost to see where you are ahead or behind
• Compare relative differences in performance visually, not just numerically
• Add small multiples (e.g., Detailed Scope Levels) to break the chart into multiple views
• Create both an overall project chart and detailed multiples for deeper analysis
• Scale breakdowns by floors or other levels in seconds — saving days compared to manual methods

This flexibility allows teams to quickly identify trends, isolate problem areas, and present both high‑level and detailed views side by side.

Good dashboards visualize progress in ways that reveal the story behind performance.
