Linking charts with a shared legend control

Oakmark’s Fraud Analytics team needs consistent visuals to compare merchants across different fraud reports.

You’ll build two charts both colored by Merchant Name:

• A stacked area chart to show monthly call volume by merchant
• A bar chart to show how much of that activity involved fraud-flagged calls

To keep the colors consistent across charts, you’ll convert one chart’s legend into a Legend Control and configure it to control both visuals.
