Line & Area Chart Maker

A line and area chart combines two visualization styles: a filled area that shows volume or magnitude, and a line that shows a trend or comparison metric. The area fills create visual weight and emphasis, while the line provides a clear reference point. This combination is excellent for showing how two related metrics interact over time.

This chart type works best when comparing two metrics where one represents a baseline or context (the area) and the other shows a specific trend (the line). Examples include total website traffic (area) vs organic traffic (line), overall sales (area) vs a specific product line (line), or team capacity (area) vs actual utilization (line).

Use the Fill Opacity slider in the Area Series section of the Data tab. Lower opacity values make the area more transparent, allowing the line and grid to show through more clearly. Higher values create a more solid, prominent fill. Adjust based on whether you want the area or line to be the primary focus.

Absolutely. This chart type is perfect for comparing team performance. The default example shows exactly this use case. You can track one team as an area to show their cumulative progress and another as a line to compare against it. Its visual design makes it easy to spot when one team is outperforming the other at a glance.
