Smoothed line chart

Smoothed line chart

A smoothed line chart shows how quantitative data is changing over equal time intervals, such as months, quarters, fiscal years, and so on. The lines that connect the data points are rounded to avoid jagged edges. Values are represented on the y-axis, whereas categories (time intervals) are displayed on the x-axis.

When to use

Use a smoothed line chart to view trends and relationships in a high-density dataset. If you use this chart type for normal or low-density datasets, the data may be distorted and misinterpreted.

  • Tooltip – (Optional) One or more measures
